'King of the Kebab' Match!

by Davide Nastasio
12/2/2018 – Can a master level blitz match be more exciting than an elite level match? Are amateurs or semi-pros able to showcase their creativity, imagination, dazzling combination and sacrifices as well as the big guns? Is over-the-board (OTB) chess more exciting than online chess and streaming? The answer two all these questions a resounding, yes, argues DAVIDE NASTASIO, who presents many positions from a recent match — Meruga vs Mbonu (pictured) — that he finds useful for training. Blitz rules like touching a piece or losing because of an illegal move don't exist in online chess. In OTB chess this makes the difference between life or death! So don't miss the chance to add some tactical ideas or endgame learning to your arsenal!

Master level blitz

Last month, at a local restaurant in Duluth, Georgia, two masters challenged each other to a 12-game blitz match for the title of 'King of the Kebab'! When two National Masters cross swords the air electrifies and the fight is to the final clock press.

David Mbonu [pictured before the beginning of the match] became a NM (in the USA that means reaching a 2200 USCF rating) in May 2017. His long time-control rating now is 2166, while at blitz he's rated 2054.

Shanmukha Meruga became an NM in July 2016. His rating for long time controls is 2305, and his blitz rating 2183. If one were to make a prediction based on the rating alone, clearly Meruga should be the winner.

Mbonu describes himself as the most aggressive (on the board) National Master in the state of Georgia. And he also teaches this berserk attacking style to his students.

I got a text message on a beautiful Saturday afternoon. That morning I'd gone for a run in the park, in order to prepare myself physically for the future match I'll play in December — a brutal affair comprised of six long time-control games, and ten blitz games played over Saturday and Sunday.

Shanmukha Meruga asked me if I was interested in recording a blitz match against another Master-level player. I decided to do it because I knew both players are dedicated and passionate about the game and I would witness a unique show.

We are now in the habit of often watching these matches at GM-level online, but the online experience cannot compare to a real game over the board. Let me tell you why.

First of all: the pieces. I have a good collection of chess sets and boards, and for this match, I lent one of my sets, called Fierce Knight, valued around USD $250, and wood board (around $100). I believe playing on wood pieces, especially some nice ones, can enhance the chess experience.

Those are some fierce knights!

Then, of course, there are other factors. When playing blitz over the board one cannot pre-move, like with online games. One cannot place a piece precisely at the intersection of three different squares (yeah the squares are 2½ inches and they can still put it in the middle of three different squares, not enough space for their pieces to actually place it in the centre of a square), begging the question as to which one it is exactly a few moves later, when nobody remembers.

Another factor is the adrenaline rush when there are only 20 seconds left and one could have a material advantage, yet be unable to physically move fast enough and hit the clock. And then there are the illegal moves, which terminate a game immediately! Yes, in blitz chess if one leaves the king in check, the opponent can take it and win the game. This doesn't happen online, because the software doesn't allow it. But what about promotion? Online, I choose to automatically promote to a queen, in real chess one must get to the queen, and in time scramble could have problems in placing it over the board. Again, this is one reason why I consider OTB chess more of a sport. While online chess is good enough to practice some openings, it's not quite the same level of intensity, in my view.

Before the match, I thought Meruga would win easily. He is a smart guy, quite passionate about chess, and generally keen to play as often as he can. Considering his priority is not chess but medical school and biochemistry, nowadays he cannot play chess as often as he did when he was in high school.

NM Mbonu on the left, NM Meruga on the right

Mbonu also had to give up part of the chess activity to finish his own degree. While other kids wanted to be firemen or astronauts when they grew up, Mbonu wanted to become a sophisticated electrical engineer. (If he was living in the former Soviet Union, he could have been working with Botvinnik and do both!) In any case, I thought Mbonu was rustier than Meruga, so I believed the match would be a one-sided story with Meruga winning 9 to 3.

Instead, the match was bitterly fought till the last pawn in the last game! The final result was a 6½ to 5½ win for Mbonu!

By the end, I felt the disappointment of Meruga for failing to win, I couldn't stop feeling a sense of elation for having witnessed an amazing match, worthy of those boxing matches of the past with Muhammad Ali and Joe Frazier, or other champions.

I'd like to share the games, with my own annotations. Please pay attention to the variety of openings they used to probe each other, and discover in which one there was a weakness. The endgames are quite interesting because most of the rook manoeuvers were played with only a few seconds on the clock, showing a big difference between a master player and the club player in the quality of the endgames.

Parnell Watkins was the Tournament Director officiating the match

And then, of course, there is the USCF rules component — quite worthwhile in my opinion. Today many tournaments are played over the year, and many young players are unclear on the rules.

In game 6 you'll witness a mess caused by White knocking over some pieces, and putting them back incorrectly over and over. The blitz rules, using the US Chess Federation's book, 6th edition, at page 311 rule 7d, defines the win as:

"Who, after an illegal move is completed by the opponent, takes the king, (if the king is in check) or claims the win and stops the clock, before the player determines a move and provided the player has sufficient mating material as defined in rule 7c."

When there were a few minutes break during games, I used them to gain some improvement tips like the following:

Davide Nastasio: NM Meruga could you give our readers a tip on how to become better players?

Shanmukha Meruga: Don't worry about your rating! You should never worry about your rating, just focus on your moves!

And then I asked the winner of the match:

Davide Nastasio: Can you give a tip to our readers, to tell them how you became so strong?

Mbonu David: Play a lot! A lot of tournament games, and a lot of online games against stronger opponents.

I grouped the first four games together because they were clearly a warm-up to the dazzling action and battle which came later. From game five, each game has some critical positions as exercises.

Game 1 1.e4 d6 2.d4 e5 Black is trying to enter an endgame, after the exchange of queens. 3.Nf3 Now we could be in a Philidor defense, depending on how the two players continue. 3.dxe5 dxe5 4.Qxd8+ Kxd8 To evaluate the position as better for White, due the enemy king is in the center, is wrong. Yes, dangerous-looking attacks can be undertaken, but if one watches enough games with this line, he would discover the Black king is not in danger. 5.Bc4 Be6 This move is quite counter-intuitive, so one does need to study the theory! 6.Bxe6 fxe6= 3...Nc6 4.Nc3 exd4 5.Nxd4 Bd7 6.Be2 g6 7.0-0 Bg7 8.Be3 Nge7 9.Qd2 0-0 Finally Black castled and now White can attack! 10.f4 Nxd4 11.Bxd4 Bxd4+ 12.Qxd4 Now Black has a complex of weak dark squares around his king, which can be exploited by White. Nc6 13.Qd2 Qf6?! Maybe not the best move to stop White from opening the position with e4-e5. 14.e5± Qe6?! 15.Nb5 Attacking the c7 weakness. Rac8 16.exd6 cxd6 17.Nxd6 White has a great position, and a slight material advantage. Who can ask for more? Rc7 18.Bc4 Now we see why e6 wasn't a good square for the queen. Qe7 19.f5 19.Rae1! Probably a better move. After all after 18 moves the rook was stuck on a1 doing nothing. 19...Bxf5 20.Nxf5 gxf5 21.Rxf5 Black has some king safety issues. Ne5 22.Bb3 Ng6?! 23.Raf1 Qe8? 24.Qf2 24.Qh6! This seems quite strong with the threat of Rh5, the f7-pawn is pinned, so Black can only play one move. Kh8 25.h4 f6 26.h5 Ne7?? 26...Rg7 Strange as it sounds, this is the best defensive move for Black. White is winning no matter what. 27.hxg6 Rxg6 28.Qh4+- 27.Rxf6 Rg8 28.Rf7 And Black is lost. 24...Re7 25.h4 Kh8?! White took nearly 20 seconds to decide on the next move. 26.Rxf7?! 26.Bxf7 This is the best move for White. Rfxf7 27.Rxf7 Rxf7 28.Qxf7 Qxf7 29.Rxf7 Nxh4 30.Rxb7 Now White wins thanks to the rook mobility, the slowness of the knight, and three pawns which cannot be stopped! 26...Rexf7 27.Bxf7 Qe5 28.h5 The h5-pawn cannot be touched! Ne7 29.Re1 Qd6 30.Rxe7 Qd1+ 30...Qxe7 31.Qd4+ Qf6 32.Qxf6# 31.Re1 Qd6 32.Rf1 Kg7 White was thinking of playing Qg3, and picked up the queen, but in moving it from f2 to g3 he realised g3 is under control of the Qd6, and kept the queen in his hand trying to find a better place. At the moment both players are short on time. White has 32 seconds, Black 34. 33.Qf5 33.h6+! Kxh6 34.Qe3+ Kg7 35.Qc3+ Kh6 36.Rf6+ White wins. 33...Qd4+ 34.Kh2 Qh4+ 35.Qh3 Qe7 35...Qxh3+ 36.Kxh3 Rxf7 37.Rxf7+ Kxf7 38.Kg4 And White wins easily in the pawn endgame. 36.h6+ Kh8 37.Qc3+ 1–0

1.d4 d5 2.c4 c6 3.Nf3 Nf6 4.g3 The Catalan, a very interesting opening. e6 5.Bg2 Nbd7 6.Qc2 Bd6 7.0-0 0-0 8.Rd1 Ne4 9.Nc3 f5 Cementing the grip over e4! This is a Stonewall formation, like in the Dutch Stonewall. 10.b3 Ndf6 11.Bb2 Nxc3 12.Qxc3 Ne4 13.Qc2 Bd7 14.e3 Be8 15.Nd2 Qg5 16.Qd3 Bh5 One can feel it. Like a thunderstorm in Summer, something bad is going to happen on the kingside, if White doesn't start to bring troops in! 17.f3 Nxg3! 18.hxg3 Bxg3 19.Nf1= 19.Ba3! White probably didn't play against the Dutch Stonewall. This is a typical move, because the exchange hub, f8, is where the rooks come to go to attack the kingside. Controlling f8, gives Black problems. 19...Rf6 Black decides to bring more troops in! Now for the next move White burned 50 seconds!! 20.Nxg3 Qxg3 21.Rf1 Rg6 22.Qd2? Now Black is better. White needed to play Qe2 to support the f3-pawn. 22.Qe2 The support of f3 was essential to keep defending. 22...Bxf3 23.Rf2 Rf8 24.Ba3 Rf7 25.Bd6!= Qh3 Black spent about 20 seconds on this move. 26.Bf4 Rg4 27.Raf1?? Now Black has a decisive advantage. 27.Rxf3!= Qxf3 28.Rf1 Qh3 29.Rf2 g5 30.Bd6 f4 31.exf4 gxf4 32.Bxf4 Qh4 33.Be5= 27...Be4 28.Be5 h5??= White has only 50 seconds left at this point, and Black 2 minutes and 9 seconds. 29.Re1 29.Re2! h4 30.Rff2 g5 31.cxd5 exd5 32.Qa5 Rd7 33.Qxa7 Rxg2+ 34.Rxg2 Bxg2 35.Rxg2 Qxe3+ 36.Kh2 g4 37.Qb8+ Kf7 38.Qc8 Qh3+ 39.Kg1 Qe3+ Draw. A long line which unfortunately doesn't give a win to Black. 29...h4 30.Ree2 g5 31.Kf1?? And White put himself in checkmate! Bxg2+ 32.Rxg2 Qh1+ 33.Kf2 Rxg2+ White gave up knowing the checkmate would soon follow! 0–1

Mbonu,D2040Meruga,S21830–12018E01Blitz Match5

Game 6: one needs to watch this game to better understand the blitz rules! It is also important to better understand what a match is. When one is playing a match, there is a constant testing the opponent not only in opening theory and preparation but also on the type of positions he likes or dislikes. In this game, Meruga tested Mbonu on closed positions.

We must always be aware of possible tactics in the opening. Black played 14...Nc7 a blunder, how would you continue as White?

 
How would you continue as White?

White is winning but just blundered with 57.Kd1. It is always important to keep our minds alert to possible drawing chances, so try to find the continuation which helps Black to draw:

 
Can you find a way to draw for Black?

Game 6 1.c4 c5 2.g3 g6 3.Bg2 Bg7 4.Nf3 Nc6 5.0-0 Nh6 Keeping the diagonal open for the g7-bishop. 6.Nc3 0-0 7.d3 d6 8.Rb1 a6 9.a3 Rb8 10.Bd2 b5 11.Ne1 On this move, Meruga thought for nearly 30 seconds. Nd4 12.e3 Ne6 13.cxb5 axb5 14.Nd5 Nc7?? 15.Bc3?= 15.Ba5‼ White missed this strong pin. Clearly he needs to work more on his tactics! Now in order to avoid losing the piece, Black needs to use pieces to protect the c7-knight. This will result in about 14 points worth of pieces blocked on c7, while White can improve his pieces up to the moment the position opens, and White wins a lot of material. Rb7 16.b4 16.Nxc7?! Notice how White doesn't need to take the knight right away, but at the right moment, when everything is in the right place, he can take to increase his advantage. Otherwise it is better to keep the pin, because it is keeping three pieces immobilized! Rxc7 17.b4 Bd7 18.a4 bxa4 19.bxc5 dxc5 20.Rb7 White is better. 16...Nf5 17.Qc1 Be6 18.Nf4 Rb8 19.bxc5 dxc5 20.Nxe6 fxe6 21.Qxc5 White has a great game. 15...Nxd5 16.Bxd5 Bxc3 17.bxc3 Bh3?! 18.Bg2= Bxg2 19.Kxg2 On this move, Meruga took at least 5 seconds, showing that it is important to think with which piece to recapture. 19.Nxg2 The engine would have preferred this move. 19...Qa5 20.Qb3 Nf5?!= 20...c4! 21.dxc4? bxc4 22.Qc2 Rxb1 23.Qxb1 Qa8+ 24.Kg1 Rb8 Black is better. Now we see why the engine favored Nxg2, because the Rf1 is out of the game, while this rook will enter in White's territory threatening the isolated pawns. 21.Nc2 e6 22.e4 Ne7 23.Ne3 Nc6 24.Ra1 Ne5 25.d4 c4 26.Qb4 Qxb4 27.axb4 Nd3 This is a good outpost for the knight. However it would be stronger if there were pawns and bishops on the second and first rank. At this moment in time, White is better thanks to the control of the a-file, which can create some real threats. 28.Ra6 Rfd8 29.Rfa1 Rd7 30.R1a5 Kf8 31.Nc2 Notice how all White's pieces are converging toward attacking b5. Nb2 32.Na3 Rdb7 33.Rxd6 White's attack on b5 made the d6-pawn fall! White is better. Nd1 34.Nb1 Ke7 35.Rda6 Nb2 36.f4 f5 37.e5 Nd1 38.Kf3 Nb2 39.Rc6 Na4 40.Raa6 Rb6? Now White is winning. 41.Rc7+! Kf8 Here Black placed the king nearly on 'f9' -- yeah, you read that right -- it was half out of the board! 42.Raa7 h5 43.Rh7 43.Rg7! Everything is falling down after this move. 43...Kg8 44.Rhg7+ 44.Rag7+! Kf8 45.Rxg6 Re8 46.Rf6+ Kg8 47.Rxh5 White is picking each of the Black pawns like cherries, then once the rooks will be exchanged, the game will be over. 44...Kh8 45.Rxg6 R6b7 46.Rh6+ Kg7 47.Rxb7+ Rxb7 48.Rxh5?! 48.Rxe6 This was stronger, the f5-pawn could fall too. Rd7 49.Ke3 Rd8 50.Rf6 Rf8 51.Rxf8 Kxf8 52.d5 And the two central pawns are unstoppable. 48...Nb2 49.Rg5+ Kf7 50.h4 Nd3 51.h5 Ra7 52.Nd2 Ra2 53.Ke2 Nc1+ 54.Kd1 Nd3 55.Ke2 Ra1 56.Nf3 Ra2+ 57.Kd1??= Ra1+?? Here things are becoming hot! White has 37 seconds left, and Black 21. And as we can see in the line I give, Black missed an easy draw. I'm sure in a long time control game it wouldn't have been missed. 57...Nf2+ 58.Ke1 58.Kc1 Nd3+ 59.Kb1 Rb2+ 60.Ka1 Rf2 61.Nh4 Rf1+ 62.Ka2 Rf2+ 63.Ka1 63.Ka3?? Nc1 64.Rxf5+ exf5 65.e6+ Kg8 66.Nxf5 Ra2# 63...Rf1+= 58...Nd3+ 59.Kf1 Rf2+ 60.Kg1 Rxf3 61.h6 Re3 62.h7 Re1+ 63.Kg2 Re2+ 64.Kg1 Re1+= 58.Kc2?? White missed again the right move! One of the most exciting games! Rc1+?? Black missed again the draw! 58...Ra2+ Now if White plays Kd1, we see the line shown above for drawing. 59.Kb1 Rb2+ 60.Ka1 Rc2 61.h6 Rc1+ 62.Ka2 Rc2+ 63.Ka1 63.Ka3?? Nc1 And then checkmate on a2 once White has finished sacrificing pieces. 63...Rc1+ Draw. 59.Kd2 Ra1 60.Rg6 Ra2+ 61.Kd1??= Ra1+?? 62.Ke2 Ra2+ 63.Nd2 Nc1+ 63...Nxb4! Maybe not totally correct, but in a blitz game it would have big value! 64.cxb4 c3 65.Kd3 cxd2 66.Ke2 d1Q+ 67.Kxd1 Ra1+ 68.Kc2 Ra2+ 69.Kb3 Rg2 Unfortunately White is still winning. 64.Kd1 31 seconds left for White, 15 for Black. Nd3 65.Rf6+ Kg7 66.h6+ Kh7 67.Rxe6 And here White makes a mess, he makes pieces fall, and put them in a new position, which is not what was actually on the board. The Re6 magically goes to d5, the e5-pawn magically going to e6. And White pushed the clock. Then Black gave check with 67...Nc1; White answers Kf3 (I don't know how the king was on e2), and now White adjusts the pieces, and the Rd5 goes to e5!! This is a new level of active pieces! White then moves the Re5 (which has moved three times) to e3, but he doesn't release the grip and then puts it back to d6, and in the end plays Rd7. At this point Black realised there was something wrong (LOL), and tries to pause the clock, but in the scramble and excitement the clock resets to 5 minutes!! As we can see over the board chess is totally unpredictable, real chess, not like the one played online! Then Black calls the Tournament Director, and they both ask to see the video I was shooting, which shows the sleight of hands made by White. White didn't do it on purpose -- unfortunately time scrambles can make a mess of everyone's mind. But the rules are clear, White committed several illegal moves, he was called on by Black, and he lost the game. 0–1

Game 7 1.e4 d5 2.exd5 Qxd5 3.Nc3 Qd8 4.d4 c6 5.Bc4 Nf6 5...Bf5 This move makes sense, because one plays the Scandinavian because he wants to develop the light-squared bishop. In this position, the g4 square is not available, but f5 is! However it can be dangerous! 6.Bxf7+! Kxf7 7.Qf3 e6 8.g4 Nf6 9.gxf5 exf5 10.Bd2 White is slightly better for the engine, from a human point of view, to expose the enemy king in this way is a good advantage. 6.Nge2 This move closes the diagonal, so the sac on f7 we have seen above doesn't work anymore, and Black can actually develop the c8-bishop to f5. b5 7.Bd3 Bb7 8.0-0 Nbd7 8...e6!? Maybe this was more important at this point, because Black needs to remove the king from the center. 9.a3 a6 10.Bf4 e6 11.Qd2 c5 Strangely White thought a lot on the next move, and by this point White had three minutes on the clock, and Black had four minutes and 26 seconds! 12.Bg5? h6? 12...c4! Black... and White, missed this move. 13.Bf5 13.Be4?? Bxe4 14.Nxe4 Nxe4 15.Bxd8 Nxd2 16.Rfd1 Nf3+ 17.gxf3 Rxd8 Black is winning. 13.Bxh7?? Rxh7 14.h3 Qc7 Black has a decisive advantage. 13...exf5 Black is better. 14.Ng3 Be7 15.Rae1 0-0 16.Nxf5 Black is still better, but White can try and attack on the kingside, once the b7-bishop is blocked. 13.Bxf6 Nxf6 14.dxc5 Bxc5 15.Rad1 0-0 16.Qf4 Qb6 17.Ng3 Rad8 18.Nce4 Be7 19.b4?

We switch from Black is better to White is better! Obviously the problem is the unprotected queen on c3, and the king on g8, a light square. 23.Nh5 White missed the tactic. 23.Bh7+! Kxh7 24.Qxc3 Rxd1 25.Qc7 Bd4+ 26.Kh1 Rxf1+ 27.Nxf1 White is better. 23...Bg5?? And Black missed it too! 24.Bh7+ Kxh7 25.Qxc3 Rxd1 26.Qxg7# 1–0

Game 8: This is the real deal. In today's chess world a warrior must be always ready to fight! Meruga switches to 1.e4 to keep his opponent on his toes while probing the enemy preparation.

Black just played 15...Qc5 which is a blunder, however, one must feel out the combination which will give a better position and some material advantage. Take your time and then play it against the engine:

 
Can you feel the combination?
White to move

Then there are also important rook endgames one should know how to play. Here White played 48.Rxf7. How should Black continue? In the game, Black blundered but, if one finds the right continuation, it is a draw!

 
Can you draw this endgame?
Black to move

This game was really instructive for the endgame. Don't miss the annotations.

Game 8 1.e4 c5 2.Nf3 d6 3.d4 cxd4 4.Nxd4 Nf6 5.Nc3 g6 6.Bc4 Bg7 Shhhh nobody tell Black the Dragon has been refuted! Sac, Sac mate! 7.0-0 0-0 8.Bg5 Nc6 By this point Meruga was out of theory, because he began to think. 9.Bb3 Bd7 Mbonu was also out of theory -- it took him 20 seconds to play this move. 10.f3 Nxd4 This is a move Black thought for a long time, 30 seconds. 10...Qb6 The engine would prefer this. 11.Be3 Ng4! 12.fxg4 Bxd4 13.Bxd4 Qxd4+ 14.Qxd4 Nxd4= 11.Qxd4 h6 12.Bh4 a6 13.Rad1 Here Black should have understood that the c-file doesn't mean much, if the enemy king is not castled there. Rc8 13...g5!?= 14.Rfe1 14.Qa7 White also missed some subtle differences in the position. 14...Qa5?! 15.Kh1 This move, needed because White fears future exchanges in the centre with possible gain of a tempo by Black if he can give check on d4, creates a back-rank weakness. 15.e5! dxe5 16.Rxe5 White has a centralised position, with active pieces. 15...Qc5?? 16.Bf2?= 16.Qxc5! Rxc5 16...dxc5?? 17.e5 g5 18.exf6 Bxf6 19.Rxd7 White is winning. 17.e5 Ne8 18.Bxe7 Rxe5 19.Rxe5 Bxe5 20.Ne4 White is better. 16...Qxd4 17.Bxd4 Bc6 18.Re2 b5 19.Nd5 Nxd5 20.exd5 Bd7 21.Bxg7 Kxg7 22.Rxe7 Again White is slightly better, thanks to activity of the pieces, and the isolated d6-pawn. Bf5 23.c3 Rfe8 24.Rde1 Rxe7 25.Rxe7 b4 26.Re3 bxc3 27.bxc3 Rc5 28.Kg1 Kf6 29.Kf2 Bd7 30.g3 a5 31.a3 Bb5 32.Ke1 Bc4 33.Bxc4 Rxc4 34.Kd2 Ra4 Here Black offered a draw. White had 1 minute 40 seconds, Black 1 minute 19 seconds. 35.Kd3 Rxa3 36.Re2?! 36.Kc4!? Ra2 37.Kb5 Ra3 38.Kc6 a4 Definitely difficult to calculate in blitz if this is worthwhile or not. 36...Ra1 37.f4 a4 38.Rb2 a3 39.Rd2 Kf5 40.Kc4 Ke4 41.Re2+ Kf3 42.Re7 Rb1 43.Ra7 Rb2 44.Rxa3 Rxh2?! 45.Ra6 Kxg3 46.Rxd6 Kxf4 47.Rf6+ Ke5 48.Rxf7 Rd2?! Komodo 11 64-bit: 48...g5 49.Re7+ Kf5 50.Kc5 g4 51.Rf7+ Ke4 52.Re7+ Kf5 49.Re7+ This is definitely an interesting endgame to analyse. Kf6? 50.Re6+?= Kf7?! Komodo 11 64-bit: 50...Kf5 51.Kc5 h5 52.Re8 g5 53.c4 h4 54.Rh8 Kf6 55.d6 Kg7 56.Rh5 Kg6 57.Rh8 Kg7 51.Kc5 h5 52.c4?!= h4 53.Re4?? Now Black is winning! g5??= 53...h3!-+ 54.d6 h2 55.Rh4 g5 56.Rh8 g4 57.Kc6 g3 58.d7 Rd1 59.Kc7 g2 Black wins. This endgame is very complex, everyone should play it against an engine, and see what happens with different moves. 54.d6? h3 55.Re7+ Kg6 56.d7 h2??= 56...Rxd7! 57.Rxd7 g4 58.Rd6+ Kg5 59.Rd5+ Kh4 60.Rd8 g3 61.Rh8+ Kg4 62.Kb6 g2 63.c5 Kf4 64.Rf8+ Ke4 65.Rg8 h2 66.Rxg2 h1Q This is a typical endgame one should know. 57.Re2?? Here Black is clearly winning, but how should he continue? h1Q??+- 57...Rxe2! 58.d8Q h1Q 59.Qg8+ Kf5 60.Qf8+ Kg4 61.Qc8+ Kg3 62.Qc7+ Kf2 Black wins. 58.Rxd2 Qg1+ 59.Kc6 Qe1 60.d8Q By this point White has 34 seconds, and Black 16, and Black resigned. 1–0

Meruga,S2183Mbonu,D20401–02018B70Blitz Match8

Volume one of the DVD deals with 9.Bc4, White's sharpest option, and shows how Black can counter this ambitious try by White with the main lines of the Soltis variation (12.h5), which was played by Magnus Carlsen regularly as well.


Game 9: Meruga definitely felt the Scandinavian failed him, so he switched to the Sicilian.

1.e4 Mbonu trying to even the score returns to his favorite e4, the 'best by test'. At this point in the match we are 4.5 to 3.5 in Meruga favor. c5 2.Nf3 d6 3.d4 cxd4 4.Nxd4 Nc6 5.Nc3 Bd7 6.Bc4 Nf6 7.Bb3 Nxd4 8.Qxd4 e5 The different pawn structures one can have with the Sicilian are quite fascinating. Each one with different weaknesses and advantages. 9.Qd3 Be7 10.f3 White is signalling this game will be a live or die fight. The message delivered with this move is to expect castling on the queenside, where Black has a semi-open file, and a wild attack on the kingside. a6 Black is in no rush to tell White where he is going to put his own king. 11.Be3 Rc8 12.0-0-0 12.g4 also playable. 12...Qa5 13.g4 Be6 14.Nd5?! 14.Kb1 removing the king from the line of fire of the c8-rook was definitely better! 14...Bxd5 15.Bxd5 Nxd5 16.Qxd5 Qxd5 17.Rxd5 Kd7 18.Rhd1 Ke6 19.b3 Rc6 20.Kb2 b5 21.c3 Rhc8 22.R1d3 g6 23.g5 f5 24.exf5+? 24.gxf6!= 24...gxf5 25.h4 h6 26.g6 h5 By this point White had 1 minute on the clock, and Black had 3 minutes. 27.Bg5 Bxg5 28.hxg5 Rg8?! 28...f4! This was better, because it fixes the f3-pawn and gives space to the Black king if he wants to attack the enemy pawns, or support the kingside. 29.f4 exf4 30.R5d4 Rxg6 31.Rxf4 Rxg5 32.Re3+ Kf6 33.Re8 Rc5 34.Rd8 Ke5 35.Rf1 Rd5 36.Ka3 h4 37.Rf8 Rh5 38.Rh1 h3 39.Rh2 Rd3 40.Kb4 Rg3 41.Re8+ Here the rook was giving check from the middle of the line between f8 and e8. Kf4 42.Ree2 Kg4 43.a4 f4 44.axb5 axb5 And here White with only 25 seconds on the clock (Black had 1 minute and 44 seconds) played Kxb5, something which online is impossible to play, and his king got taken by Rxh5 winning the game. However Black is winning, since it is impossible to stop the two passed pawns. 0–1

Mbonu,D2040Meruga,S21830–12018B57Blitz Match9

Before going to Game 10, we need to understand the situation in the match. Meruga has 5½ points. If he just wins one more game he has won the match. If he draws, Mbonu still has a chance. From the outside, both players were cool and didn't show signs of nervousness which would betray their real feelings.

Game 10 was interesting for how, in a blitz game, the evaluation can change. For example, Black has just played 51...Rgg8, a big mistake. Can you win against the engine?

 
Black just blundered...
White to move — can you win against the engine?

Another exercise: After 56...Kd7, do you see the checkmate in two?

 
Can you see the checkmate in two?

1.d4 Nf6 2.Nf3 d5 3.Bg5 c5 This move provides some pressure against the d4-pawn, while opening the diagonal to attack the b2-pawn. 4.c3 Qb6 5.Qb3 c4 6.Qxb6 axb6 While the engine gives the position as equal, Black is practically slightly better. He is already applying pressure on a2, and the pawn structure is typical of a reversed London, where Black can organize a minority attack on the queenside. 7.a3 e6 8.Nbd2 Nc6 9.Bxf6 gxf6 Black now has a grip on e5, preventing White from playing Ne5, and an open file to White's possible castling position. 10.e4 Rg8 Black took more than 20 seconds to play this move. Again, knowing the thinking time is important because it tells us about the problems in one's own game. In this case Black had to decide upon a plan. 10...Bh6 Another possible move. 10...b5 Also this move was playable. 11.g3 Bh6 12.Bg2 dxe4 13.Nxe4 Ke7 14.Nfd2? White didn't realise he cut the only retreat square for the e4-knight. Na5 Black noticed, but preferred to prevent any possible escape. Notice how important it could have been to play b5 to support the c4-pawn before. 15.Bf1? f5 Here Black took about 10 seconds to play this move, likely to check his calculations once more. 16.f3 fxe4 17.Nxe4 f5 18.Nf2 Nb3 Black has a decisive advantage, but the position is semi-closed, and kind of solid. But how to convert it into a win? Black has only 2 minutes and 49 seconds left. 19.Rd1 b5 20.f4 Bd7 21.Bg2 Bc6 21...Bxf4! This tactic would help a little to open the position. 22.Bxb7 Rab8 23.gxf4 Rxb7-+ And now Black should be able to double on the g-file, and penetrate in enemy territory. 22.Bxc6 bxc6 23.Ke2 Kd6 24.Kf3 Bg7 25.Rhe1 Bf6 26.Re2 Rae8 27.Rde1 Na5 28.Nd1 Nb7 29.Ne3 Kd7 30.Nc2 Nd6 31.Ne3 White doesn't want to open the position, and just wait for Black to find a way. Ne4 32.g4 Nd6 33.h3 fxg4+ 34.hxg4 At this point Black realised his king was precisely in the middle of the squares: c8-d8-d7 and c7, and decided to adjust it on d7... online we don't focus on adjusting pieces, or guess where our opponents placed theirs. Nf7 35.Rh1 Rg7 36.Reh2 h6 37.Nd1 Rf8 38.Nf2 Be7 Here White adjusted the c6-pawn, and Black thought to adjust too the king on d7, which now was back in the middle of the four d7-c7-c6-d6 squares. 39.Ke4 Nd6+ 40.Ke3 Nf7 41.Rh5 Rg6 42.R5h2 Bd6 Both sides have 1 minute left on the clock. 43.Rh3 Nd8 44.Rf3 c5 45.Ne4 cxd4+ 46.Kxd4 Nc6+ 47.Ke3 Bc7 48.Rd1+ Ke7 49.g5 Bb6+ 50.Ke2 e5?= 51.f5 Rgg8?? 51...Rxg5! 52.f6+ Kf7 53.Rd7+ Ke8 54.Rg7 Rg1 55.Nd6+ Kd8 56.Nb7+ Ke8 57.Nd6+ With a perpetual. 52.f6+! Ke8 53.Rd6? Now Black has only 38 seconds left, and White 45. The d6 square was important for the Ne4. 53.f7+! Rxf7 54.Nd6+ Kd8 54...Kf8 55.Rxf7# 55.Rxf7 Rg6 56.Nxb5+ White is winning. 53...Nd8 54.Rxb6+- hxg5 55.Rf5?! 55.f7+! Again White missed the kill shot! Rxf7 56.Nd6+ Kf8 57.Nxf7 Nxf7 58.Rxb5 White is winning. 55...g4 56.Rxe5+ Kd7 57.Rg5?? Here White missed a checkmate in 2! 57.Re7+ Kc8 58.Nd6# 57...g3 58.Kf3 g2 59.Kxg2? Rxg5+ 60.Nxg5 Rg8 61.Kf3?? 61.Rxb5!± 61...Rxg5 Once more there is a change of fate, Black should have lost many times, and yet now he is the one winning! We can see how chess is definitely a sport. White is losing energy and focus, because of the sustained effort over hours of fighting. 62.Kf4 Rg8?= Here the rook went on the square 'g10', totally out of the board, White has 32 seconds left, and Black 25. 62...Rc5! Cutting the White king from entering enemy territory. 63.Kf5 Rf8 64.Ke5?! 64.Rxb5!= 64...Nc6+ 65.Kd5 Nd8 66.Ke5 Nc6+ 67.Kd5 Kc7??+- 68.Rxb5?= Rxf6 69.Kxc4 Rf4+ 70.Kb3 Kd6 71.Rh5 Rf2 72.Rh6+ Kc7 73.Rh7+ Kb6 74.a4 Rf3 75.Rh6 Rf5 76.Ka2 Rc5 77.Kb3 Rf5 78.Rh4 Kc7 79.Rc4 Kd6 Black has only 10 seconds left...madness begins... only one will emerge victorious! 80.Ka3 Na5 81.Rb4 Nc6 82.Rb6 Kc7 83.Rb5 Rf4 84.b4 Rf3 85.Kb3 Nd4+ And here White played Rc5!! And Black took the king on b3 winning the game! Real blitz over the board! At the end of the game Black had 6 seconds left, and White 11. 0–1

Quite an active move that immediately attacks one of White's pieces, obliging a retreat. This is quite an interesting interpretation of the Scandinavian. Generally the Scandinavian guys like to develop the Bc8 to f5 or g4, like in the Caro-Kann. 7.Bd3 e6 8.0-0 a6 9.b3 Bb7 10.Bb2 c5= The engine gives equality, but Black is doing well here, he has solved all the problems of the Scandinavian, especially on the queenside. 11.dxc5 Bxc5 12.Ng3 Nbd7 13.Nce4 Be7 14.Qe2 Rc8? 14...0-0! Definitely this was the moment to move the king from the centre. 15.Rad1 15.a4! White should have attacked the queenside. b4 16.Bxa6 Bxa6 17.Qxa6 White is better. Rxc2?! 18.Nxf6+ Nxf6 19.Bxf6 Bxf6 20.Rad1 Qb8 21.Qd3 And Black has some problems. 15...Qa5?! 16.Nxf6+ 16.Nf5‼ Quite difficult to see in a normal game, impossible in a blitz game. But still worth the discovery of such a gem! exf5 16...Qb6 17.Rfe1 Kf8 17...exf5?? 18.Nxf6+ Nxf6 18...Qxf6 19.Bxf6 Game over! 19.Qxe7# 18.Nxe7 Kxe7 19.Nxf6 gxf6 White is better. 17.Nd6+ Kf8 18.Nxc8 Bxc8 19.Bxf5 And White has a decisive advantage. 16...Bxf6 17.Bxf6 Nxf6 18.Nf5± This knight is amazing, Black's position is crumbling! 0-0??+- 19.Ne7+ Kh8 20.Nxc8 Rxc8 21.c4 bxc4 22.Bxc4 Qg5 23.f3!? I'm always doubtful of moves like this one, because the opening of the g1-a7 diagonal generally leads to a disaster. But in this position I don't think there was another way. h5 24.Bxa6?! 24.Qd2!? Qc5+ 25.Qd4 Qb4 26.Rfe1 White has a material and positional advantage. 24...Bxa6 25.Qxa6 Rc2 26.Rf2 Here we see why it is important to record the thinking time. White took over 40 seconds to play this move. This is a 5-minuted blitz game and 40 seconds is definitely a lot. Now we can only speculate. This is the 11th game -- is White tired and losing the grip of the match? Because if he would lose this game, the match was over. Hence the hesitation... Qe3 White has 1 minute 46 seconds, Black has 2 minutes 53 seconds. 27.Qf1 27.Rd8+ Kh7?? 27...Ng8 This is the best defense. 28.Qf1 Rxa2 29.Rd3 Qb6 30.Qe1 Nf6 31.Qe3 Ra1+ 32.Rf1 Qxe3+ 33.Rxe3 White should be able to win, but again this is a blitz game, and one can have a material advantage, and still lose on time. 28.Qd3+ Qxd3 29.Rxd3 White has a decisive advantage. 27...Rxa2 28.Rd8+ Kh7?? Black missed the problem of the light-square diagonal which is easily controlled by the white queen. 29.Qb1+ Ne4 30.Qxe4+ Qxe4 31.fxe4 Ra1+ 32.Rf1 Ra2 33.Rxf7 Rb2 34.Rf3 e5 35.h3 Kg6 36.Rd7 h4 37.Rb7 Kh6 38.b4 Kh5 39.b5 g5 40.b6 g4 41.hxg4+ Kxg4 42.Rb8 Komodo 11 64-bit: 42.Rf5 Rxg2+ 43.Kxg2 h3+ 44.Kh2 Kh4 45.Re7 Kg4 46.Rexe5 Kh4 47.Rf4# 42...h3 43.Rg8+ and realising there is checkmate next, Black extended the hand in resignation. 1–0

Mbonu,D2040Meruga,S21831–02018B01Blitz Match11

Game 12: This is the game which decided the match. And I'd like to outline some points, because in my opinion, they prove OTB chess is, in some sense, superior to online chess. Around move 29, Black had the kill shot, but for a moment, maybe due to tiredness, he saw a ghost, an illusion of something he thought White could do. It happens. These kinds of mirages appear at the board. But what is the difference between OTB and online? He already touched the bishop on b7, so that is the piece he must move. Online he would have put the piece down, and nobody would have noticed, but once he touched the piece, his mind was divided upon: "Oh wait, maybe I don't want to take on g2, but I cannot move the rook, or another piece because I touched the bishop", so he kept the bishop lingering in the air...

 
Can you see the kill shot?
Black to move

Another important point is to be able to convert a win, once one has a good material advantage. Try to play against the engine as Black and win! (Hint: the best continuation is Nc5!)

 
Try to convert the win
Black to move

Here is the final game which, again, decided the match!

This is game 12, the decisive game of the match. Both players are on 5.5; the one who wins this game will win the match. The tension is palpable. Up to this point the gladiators have fought for 2 hours, and in this moment one must find the last ounce of energy. 1.d4 Nf6 2.c4 e6 3.Nc3 Bb4 4.Qc2 A classical Nimzo-Indian. 0-0 5.a3 Bxc3+ 6.Qxc3 b6 7.f3 As Nimzowitsch would say, now Black's light-squared bishop is going to bite granite. And White can also push and support the e-pawn. d5 A very important move. Black immediately fights for e4. 8.Bg5 And White pins the f6-knight, taking away an attacker/controller from e4. Bb7 9.e3 Nbd7 10.Nh3 A strange place to develop the Ng1, but clearly White still wants to fight for e4, and brings another piece into the fight. Re8 11.cxd5 exd5 This move seems to close the diagonal for the b7-bishop, cutting it out of the battle, but as we will see, Black will try to overcome such a blockade! 12.Nf2 12.Bb5 Probably at this point this move was better, because it allowed White to castle, while leaving the e1-h4 diagonal free for a retreat of the Bg5. c6 13.Ba4 h6 14.Bxf6 Qxf6 15.0-0= 12...h6 13.Bf4 13.Bh4 Probably he didn't play this move, for the fear of losing the e3 pawn. But it is playable and the favorite of our silicon friend. 13...c5! Attacking the centre, with the idea of opening the diagonal for the Bishop on b7. 14.Be2?! 14.Bb5!?= a6 14...Nh5 The enemy king is in the centre, so we are told to attack immediately. But in this case the king is able to escape. 15.0-0 Nxf4 16.exf4 Rc8= 15.Bxd7 Qxd7 16.0-0 Rac8 Black is slightly for choice. 14...Nh5! 15.Bg3?! Nxg3! 16.hxg3 Qg5 We must remember Bronstein who said: "Chess is a game of double attacks." And here it appears difficult to find the right move to defend the pawns on g3 and e3. By this point Black had used 25 seconds, while White used 1 minute and 3 seconds. Clearly White is in trouble. Why? Because he is thinking a lot on the next move, which means Black posed a problem he didn't think of, and doesn't know how to solve. 17.f4? To find this move White took nearly 30 seconds!! One must understand this is a 5 minutes game, no delay, no increment. It becomes particularly cruel when one player is able to gain a decisive material advantage but he doesn't have enough time on the clock to give checkmate. In this case White is losing material, and the position is going to get worse. 17.Ng4 The engine prefers this move. h5 18.f4 Qg6 19.Ne5 Nxe5 20.fxe5 Qxg3+ 21.Kd2 g6 Black is better. Notice the difference with the rest of the game, the engine has found a way to cover the e3-pawn from the pressure exerted by the Re8. 17...Qxg3 For the engine Black has a decisive advantage. 18.Bf3 Qxf4‼ White totally missed this continuation! The e3-pawn is pinned! 19.Kd2? Shocked White couldn't find the best defensive continuation. 19.0-0 For the engine this is the best try. However from a human point of view the situation is bad! Rxe3 20.Nh3 Qxd4 21.Qxd4 cxd4 Black is winning. 19...cxd4?! This is not the best move for the engine. 19...Qg3 This was the best move for the engine, because it keeps the pressure, and White doesn't have any counterplay, but from a human point of view, he decided to exchange material to win in the endgame. 20.Ng4 Rac8 21.Rac1 cxd4 22.Qxd4 Nc5 Black is winning. 20.exf4 dxc3+ 21.bxc3 Nc5 22.Rab1 Rac8 By this point Black has 4 minutes left, and White 2 minutes 51 seconds. 23.Nd3? Ne4+! 24.Bxe4 dxe4 25.Ne1? Being on the outside often makes finding moves easier. When I saw this move I thought it was bad for White, and I'd have preferred Ne5 or Nb4. e3+ Now finally the diagonal for the b7-bishop is open! 26.Ke2 White has a lot of problems. The h1-rook is out of the game, the b1-rook is not really attacking anything, and the king on e2 is under fire from the enemy artillery. Rxc3 27.a4 Ra3 28.Rb4 Ra2+ 29.Kf1 This is the proof that OTB chess is definitely superior to online chess. Here Black took over 25 seconds to move!! He touched the b7-bishop but doubted himself if it was correct to take on g2! And once the piece was touched, he couldn't change to another piece. Bd5? 29...Bxg2+‼ This is what Black wanted to play, but then he saw: 30.Kg1 and since Black is focused on getting the e3-pawn to promotion, psychologically the Ne1 is blocking it, so the Bxg2 move seems it doesn't work, but it does, since it is the winning move. 30.Nxg2 The better defence for the engine was this move. e2+ 31.Ke1 31.Kf2 e1Q+ 32.Kf3 Qxh1 And here Black checkmates in few moves. 33.Kg3 33.Rb2 Qh3+ 34.Kf2 Rxb2+ 35.Kg1 Qxg2# 33...Rxg2+ 34.Kf3 Qh3# 31...Ra1+ 32.Kd2 Rxh1 and the game is over. Black wins the game and the match! 30...Bxh1 31.Rb1 Now the point is that White has kept control of the e1 square, so Black is winning, but in his mind not winning like he wanted. Bb7 And Black is winning. 30.Rh3 Re6 30...Bxg2+ Now this move is not strong as before. 31.Nxg2 e2+ 32.Ke1 Ra1+ 33.Kd2 Rd1+ 34.Kc2 Rg1 35.Rb1 Rxg2 36.Re1 Black is still winning, but White blocked the pawn, and since this is a blitz game, Black can lose on time. 31.Rd4 Bc6 31...Bxg2+ Now this was the strongest move for Black. 32.Nxg2 e2+ 33.Ke1 Ra1+ 34.Kd2 Rd1+‼ 35.Kc3 Rc6+ 36.Rc4 Rc1+ 37.Kd3 R6xc4 Black wins. 32.f5? e2+?! 32...Rf2+! 33.Kg1 Rxf5 Black is winning. 33.Kf2 Rf6 33...Re5 34.Re3? Luckily White continues to find the wrong move, and help Black in winning! Rxf5+ 35.Nf3 Rxa4?! 35...Bxf3 This typical exchange/maneuver or pattern happens quite often. 36.gxf3 e1Q+ 37.Kxe1 Rh5 38.Kd1 Rhh2 39.Rc4 Ra1+ 40.Rc1 Rh1+ Black wins. 36.Rxa4 Bxa4 37.Rxe2 How brutal is chess? The pawn who thought would become a queen has just been killed! Bc6 38.Re7 Bxf3 39.gxf3 Black decided to go brute force, he will win materialistically. He can do it, because he has 1 minute and 58 seconds, while White has only 1 minute and 4 seconds. a5 and now again has become a pawn race! 40.Ra7 White clings to the hope his opponent doesn't have enough technique to convert the advantage into a win. Unfortunately for White, he has plenty! Rb5 41.Ke3 Rb4 42.f4 g6 43.f5 gxf5 Why is White still playing? Two reasons: 1. He can still end in a situation where Black mistakenly stalemates White. 2. Black can lose on time, even if that's unlikely. 44.Kf3 Kg7 45.Kg3 Kg6 46.Kf3 a4 47.Ra6 Kg5 48.Kg3 b5 49.Kf2 Rb3 Now the roles of White's pieces are reversing. White will try to block the queenside majority, while trying to find a way to give perpetual check on the kingside. 50.Ke2 a3 51.Kd2 b4 52.Ra4 Rb2+ 53.Kc1 h5 54.Ra8 h4 Already at this point the engine calculates a checkmate in 17 moves in a fraction of a second. 55.Rg8+ Kf4 56.Rh8 Kg3 57.Rg8+ Kh2 58.Rh8 h3 59.Rd8 b3 60.Rd3 Rc2+ White has 27 seconds left, against Black's 1 minute and 9 seconds. Yes, this is the essence of chess, like life, a fight till the end! 61.Kb1 a2+ 62.Ka1 Now before playing the next move, Black took a queen in his hand! Rc1+ 63.Kb2 a1Q+ 64.Kxb3 And here White gave up, because he realised he'd lose immediately. 0–1

Final thoughts

Often they tell us it is useless to analyse blitz games. What foolishness! Thanks to this article we have learned common tactical motifs, ways strong players activates their rooks in the endgame, play on the seventh rank, checkmate threats/patterns, and so on. We even learned the width of the opening repertoire a master level player has! Now it is up to us to incorporate this wealth of information and improve our own games. My main point was to share the excitement for a match which filled two hours of my life with excitement and wonder.
