10/18/2019 – On October 17th, the World Junior Championships 2019 had two rounds. After the final game ended we already had clarity on who has the early lead in the event. In the open section we have three players who are sharing the lead with 3½/4 — Miguel Ruiz from Spain, Evgeny Shtembuliak from Ukraine and the local favourite Praggnanandhaa. In this article IM SAGAR SHAH analyses one game of Praggnanandhaa and one game of Shtembuliak in great depth. While Pragg teaches you the art of exchange sacrifices, Shtembuliak shows you how to play positions in which you are winning. In the girls section we have Boldbaatar Altantuya from Mongolia who is on 4.0/4 and is the sole leader. A detailed report from New Delhi. | Photo: Niklesh Jain
The positional exchange sacrifice is one of the most powerful and fascinating strategic weapons in chess. On this DVD Sergey Tiviakov explains why the positional exchange sacrifice is such a strong weapon and how to use it.
From Mating with a queen; a rook; two bishops; a knight and a bishop; to the basics of pawn endgames – here you will gain the necessary know-how to turn your endgame advantages into victories!

Praggnanandhaa's exchange sacrifice
A rook is worth five pawns and a bishop's worth is three pawns. This is taught to us right from the initial stages of our chess journey. However, material as a concept in chess is not static. It is dynamic in nature. A better placed bishop may well be more valuable than a rook. A rook without open files can often be quite useless. The more experienced and knowledgeable a player becomes, the better is his understanding of the material imbalance in chess. In my opinion, in the fourth round of the World Junior Championships, Praggnanandhaa showed the positional understanding of the highest nature. He played an exchange sacrifice which would have made the master of exchange sacrifices Tigran Petrosian smile.
Petrosian would often sacrifice an exchange and not worry about doing something concrete immediately. This is exactly what Praggnanandhaa did in round four.
Praggnanandhaa - Batsuren, round 4
Position after 19...Qe7
White has maximized his position. Time for a plan. What do you think?
Praggnanandhaa took 15 minutes on his clock and came up with a very interesting one. He saw that the Black weaknesses are mainly on the queenside — the c6 and a6 pawns being the main ones. Hence, a knight on b4 would be ideally placed. How to get it there?

Pragg played the move 20.♕d2!? with the idea of ♘a1-c2-b4. His opponent at first didn't grasp what Pragg was up to, but when the youngster moved his knight to a1, Dambasuren was jolted into action.
Position after 21...h5
The Mongolian IM played the move 21...h5!? His plan was to attack the queen with ♝h6. The normal move would be to move the queen or the rook. But Pragg boldly went ahead with 22.♘c2!?
Position after 24.♕xc1
White is a complete exchange down. But Pragg is not looking for immediate returns. He would like to build up his position and at the appropriate moment, open up things with f4.
Position after 27.dxe4
Black's decision of resolving the tension in the centre with 27...dxe4 28.dxe4 was incorrect as now the bishop comes to b3 and becomes an extremely powerful piece. Also, the dark squared weaknesses around the black king will start to make itself felt when White goes f4!
Position after 31.f4
The f4 move finally comes in. Notice how Black's extra material is not at all important in this position. The quality of White's pieces is vastly superior.
Position after 36.e5
The final blow to open up the position. The picture says it all. Praggnanandhaa went on to win a very nice game!
Praggnanandhaa's opponent was no pushover. He is a strong IM with an Elo of 2454. But he was unable to sense the changing nature of the position and its dynamics as well as the 14-year-old could. This game is an excellent example to illustrate the talent of the youngster.
The Ruy Lopez is one of the oldest openings which continues to enjoy high popularity from club level to the absolute world top. In this video series, American super GM Fabiano Caruana, talking to IM Oliver Reeh, presents a complete repertoire for White.

1.e4e52.Nf3Nc63.Bb5Praggnanandhaa likes to play the Italian but today
goes for the Ruy Lopez. It's quite nice to see that he is ready to play
different openings and has good preparation in almost all lines.a64.Ba4Nf65.d3d66.c46.c3is the main line.6...g67.Nc3Bg78.Nd5h68...0-09.Bg5is a line that Pragg had prepared.9.Nb4The move h6 stopped
Bg5, but the drawback is that it allows Nb4.Bd710.Nxc6bxc610...Bxc6
It's an open question as to what is better. While taking on c6 with the bishop
means that Black has more space to place his queen on d7, the remaining bishop
on the board - the g7 one is not a great one for Black.11.Bxc6+bxc612.0-011.c50-012.0-0In this position Pragg felt that the best way for
Black to continue would be place his knight on h5 and then break in the center
with f5. However, Batsuren had no such active plans in the game.Re813.Nd2!?The plan is to place the knight on a5 via c4 or b3.d514.Qc2Re6
The rook is not so well placed on e6. Black should have played something
active. Moves like Re6 mean that Black is ready to play the waiting game.15.Nb3Kh716.Bd2Qe817.Rac1Improving his pieces!Rd818.Ba5Rc819.Rfe1!?The rook is better placed on e1 than on f1.Qe7White has maximized his
position and now it is time to come up with a plan.20.Qd2!Pragg's idea
is quite deep. He sees that Black has two weaknesses - one on a6 and the other
on c6. In order to attack them both, the white knight should reach b4. How
does his knight reach that square. Na1-c2-b4!Qd821.Na1Only when
Dambasuren sees that things are becoming quite serious, does he try to do
something concrete. His idea now is Bh6.h522.Nc2!A powerful decision.
It is quite reminiscent of Petrosian's exchange sacrifices, where the former
World Champion would give up his rook for a minor piece, and then continue the
game as if nothing had happened.22.Qb4is a natural move trying to save
the exchange, but Pragg doesn't cling on to his rook.22...Bh623.Qd1Bxc124.Qxc1The resulting position might be complex, but it is easier to
play as White. The reason is that White has quite a lot of ideas in the
position to create play on the queenside. At the same time he can open things
on the kingside with f4 at an appropriate moment. On the other hand what
should Black do? It is really not so clear.Be825.Bc3Rb826.b4dxe4?!
A bad decision by Black as now the bishop on b3 will be a complete monster.27.dxe4±Nd728.Bb3Re729.Qe329.f4Already was pretty strong, but
Pragg didn't want to get into any complications just as yet.a5!?30.Rd130.a3?Nxc5-+29...Nf630.h3Ng831.f4exf432.Qxf4Slowly but
steadily white pieces are getting closer to the black king!a5Too late!33.Nd4axb433...Rxb434.Nf3!+-34.Bb2f635.Nf3Rg736.e5g537.Qc1g438.exf6gxf339.fxg7Now Black doesn't event have a material advantage!Bg640.Re6Qh441.Qe341.Bc2+-41...Bf541...fxg242.Rxg6Kxg643.Qe6+Kh744.Bc2++-42.Qxf3Bxe643.Bc2+Kh644.Qe3+A beautiful game
by Pragg. The idea of Qd2 followed by Na1-c2-b4 was an excellent idea. It
propelled his opponent to take some action. And when Black tried to do
something, Pragg sacrificed an exchange and won his game! What a nice game.44.Qe3+Qg545.Qxe6++-1–0
In round four Evgeny Shtembuliak played on the top board against Miguel Ruiz and the game ended in a draw. However, in round three Evgeny Shtembuliak (left) played a wonderful game against Sergey Drygalov.
Evgeny Shtembuliak (left) vs Sergey Drygalov | Photo: Niklesh Jain
After the game ended we caught up with Evgeny and he gave us great advice on how to win winning positions:
When you are winning, you must try not to hurry.
You must calculate each and every possibility carefully so that your opponent cannot surprise you.
You must have the energy to sustain throughout the game. In this respect it is important that you are physically fit.
In a nutshell to become a better converter of winning positions into full point you must be patient, you must be a good calculator and you must be physically fit!
Let's have a look at how Shtembuliak managed to show all of this in his game.
Shtembuliak vs Drygalov, round 3
Position after 26.♗c5
White attacks the rook on f8 and also the bishop on f5 is hanging.
Position after 27.♖be1
White did not hurry here to take on f8 and instead stopped Black's plans of 27...e3 with 27.♖be1
Jacob Aagaard teaches in six lectures important principles of positional play.
Position after 27...e3
It is important here not to be too materialistic. Your bishop on g2 and the protected passer on a5 already guarantee you an excellent position, so why would you want the rook on f8? White just took on e3 with his bishop and was clearly better.
Analysis
Position after Qe3
One of the variations that Shtembuliak considered reached this position. It is easy to say White is winning here. But a good converter of better positions always looks at opponents resources. Here Shtembuliak saw that Black can play ♜xg2+ and after ♔xg2 ♛a8+, he can pick up the a6 pawn. Yes, White is still better, but the win is greatly complicated. If you are able to see such resources for your opponent, you can convert better positions more frequently.
Analysis
Position after 37.Bxa8
This is one position which I simply fell in love with. Black to play. What do you think is the evaluation of the position?
White is a rook up, so he must be better, right? Well, Black plays the move 37...f6! here and...
The third part of the endgame series tackles queen endings, rook against minor pieces, queen against rook and queen against two rooks. Queen endings are not nearly as mysterious as they appear at first sight. Knowing a few rules of thumb and principles will make things very much easier for you. Over 7 hours video training.
Analysis
Position after 37...f6
...the queen on e8 is greatly overloaded! It cannot defend both the bishop on a8 and the rook on e1. The game ended in a draw!

1.c4e52.g3Nf63.Bg2Nc64.Nc3Bb45.e4Bxc36.dxc30-07.Qc2!?
Shtembuliak wants to develop his knight on f3 because it is well placed on
this square and can go to f3-d2. This knight can then be manoevured in a nice
way to move to d5 via f1-e3. That's the reason why the e4 pawn has to be
protected. Also possible was to play Qe2.d68.Nf3h69.0-0Be610.b3a611.a4Na512.Rb1Qe813.Nh4Shtembuliak changes his plans and now aims to
play more aggressively with f4.13.Re1!?was more prophylactic because
afterb514.cxb5axb515.b4Nc416.a5Now the move d5 is not possible.13...b5!?14.cxb5axb515.b4Nc416.a5The position is interesting here.
True the pawn on a5 is strong, but overall Black has a nice position because
his pieces are well placed.d5!17.exd5Bxd5If the bishops are exchanged,
the black knights will dominate on the light squares. Hence, White played the
next move.18.f3c519.Nf5cxb420.cxb4Rc821.Qf2Be622.Ne3!
Mission accomplished the knight on c4 is going to be removed.Nd523.f4e423...Nc324.Ra1exf425.gxf424.f5!24.Bxe4Nc324...Ndxe325.Bxe3Bxf526.Bc5!Bg627.Rbe1!Here we can see Shtembuliak's
excellent feel for chess. He could have simply grabbed the rook on f8 but sees
that there are issues related to the move ...e3. So he calmly moved his rook
to e1. The rook on f8 is not running away.27.Bxf8e3!?27...e328.Bxe3!28.Qe2Rxc528...Nxe329.Qxe3Yes the material is even in the
position. But the bishop on g2 combined with the a5 pawn give White a clear
advantage.Qd730.a6Rfe831.Qb631.Qf2Rc232.Rxe8+Qxe833.Re1Qd834.Qe3Rxg2+35.Kxg2Qa8+36.Qf3Qxa6This still has good chances in the
position for White, but you do not want to lose your a-pawn.31...Rxe132.Rxe1Qd233.Qe3Qxe3+?!33...Qxb4!would have given Black some
interesting fighting chances.34.a7Qa535.Qe8+35.h3!is better for
White. But why not the natural Qe8+35...Kh736.a8QRxa837.Bxa8
It seems like White is winning, after all he is a rook up. But next comes the
move ...f6!f6!=What a beautiful position. The queen on e8 is
overloaded because it cannot control both the rook on e1 and the bishop on a8.34.Rxe3Rc1+35.Kf2Ra136.Re8+Kh737.Bb7Ra338.Re5Bd339.Ke3f640.Re7f541.Kd4Kg642.Re3A very nice game by Shtembuliak.1–0
Every chess coach preaches that attacking a stranded king in the centre is the easiest thing to do, but how about attacking a king which has already castled? More often than not kings hide on the kingside, right? So, that’s a good reason for you to know how to attack a king which has castled short. FM Valeri Lilov is glad to help you in this tricky business! His DVD focuses on a number fool-proof plans and techniques for successfully destroying the enemy’s fortress to bring the opponent’s king to justice!
Altantuya - Katkov, round 4
Position after 14.dxe5
White has taken the pawn on e5. How do you recapture as Black?
It was important here to give up some material starting with 14...♞xe5 15.♘xe5 ♜xe5 16.♗xa8 ♛xa8. The resulting position is not so bad for Black, and he has very good compensation. In the game Black went 14...dxe5 and after 15.♘g5! it was all over. There were just too many things hanging - a8, d7 and also pressure on h7.

A very energetic duel was lived on the first board, where the Altantuya
player asserted her superiority and experience despite her young age.1.d4Nf62.Nf3e63.g3b64.Bg2Bb75.c4Bb4+6.Nc30-07.a3It is not the
main line, usually white prefers not to spend the time of a3 and wait for the

14...dxe5?He does not
lose instantly but in the short term the position of the Israeli player began
to collapse like a sandcastle. dxc6 seems the obvious answer but the activity
that gives to white pieces explains that even the possible exchange sacrifice
was more acceptable, for example:14...Nxe515.Nxe5Rxe516.Bxa8Now
accepting the exchage sacrifice does not seem too strong as the compensation
of the pawn and the bad bishop of the white pieces is enough for the black.Qxa815.Ng5Ra7What a sad move, was definitely better looking for
activity or contraplay but now is dificult to recover the position.16.Bc6Bc817.Bd5Re718.Bxe7Qxe719.Bxf7+Kf820.Bd5Nxd521.Nxh7+Kg822.cxd5e423.Ng5Qxg524.Qxe4Nf625.Qe7Bd726.Qd8+Kh727.Qb8Nxd528.Qxa7Bc629.Qa6Nf430.Rd4Ng631.Qd31–0

The Iran - Israel issue
In round four Iranian Aryan Gholami lost his game when he didn't show up for his game even past the walkover time. This is not a new incident in the chess world. We have seen a number of cases where the Iranian players did not turn up for their games when paired against Israeli opponents. Aryan Gholami did not just lose a point, but he got so depressed that he withdrew from the tournament as well. A medical certificate was submitted to the arbiters to show that the youngster was not feeling well and hence didn't play the round.

Another disappointing forfeit by an Iranian player against an Israeli, at the World Junior Ch. today. #FIDE is not prepared to tolerate chess being used for political purposes. Unless there are changes, strong measures will be taken. pic.twitter.com/bprcXMldlc
After reading this tweet, I wonder if we can blame the Iranian youngster for not showing up to the game. The boy if he plays the game would have to face dire consequences back home. As a player who has just become Iran's latest GM, he would have loved to play his fourth round and not throw away his point. But, it is quite possible that playing this game would put his entire chess career at risk. It seems as if this incident affected Aryan in a way that he has decided to withdraw from the event.
Spare a thought for the youngster. Being an Iranian chess player is not easy. Especially when you have guys like Firouzja, Maghsoodloo, Tabatabaei etc. who are always fighting for the top places in most of the tournaments they play. Whenever, they participate in a tournament they have to worry about being paired against an Israeli opponent and losing a full point. The Iranian government must do something about this or else these youngsters who can bring pride and glory to their nation, actually find themselves in a Zugzwang like situation, as Aryan faced at the World Juniors.
