ChessBase Magazine 210: A Review by Nagesh Havanur

Even as I write these lines, the World Team Championship has drawn to a close, with China edging out Uzbekistan, Spain and India. A salutary reminder of the strength of Chinese chess players. It’s a pity that two of the best chess teams in the world, China and Russia could not compete in the recent Chess Olympiad. As is known, China did not field its players on account of Covid restrictions and Russia could not participate on account of the FIDE ban with the invasion of Ukraine.

With the absence of Russia and China the main battle was between other contenders, the USA, India, Armenia and Uzbekistan.  As it happened, the experienced USA and Armenia Teams received  setbacks in their matches with young Indian and Uzbek Teams. Thus the scene was set for the decisive encounter between India and Uzbekistan.

India being the host had fielded two teams, "India I" and "India II". Uzbekistan had only drawn the match with "India I" Team. While Vakhidov had prevailed over Sasikiran and Abdusattorov had lost to Harikrishna:

1.e4 This game was played in round 6. At this point the young Uzbekistan team was playing exceptional chess and on board 1 Nodirbek was on 100% score. In this game he did not hide his intentions and went for a highly complicated battle. e5 2.Nf3 Nc6 3.Bc4 Bc5 4.d3 Nf6 5.Bg5 In the Italian game, trends keep changing. What was once considered harmless becomes quite scary with the help of engines and a fresh perspective. I have anticipated his choice of 5.Bg5 as he is on 100% score and recently became very popular. There are various move orders white can choose between the quiet 5.c3 or 5.0-0. 5.c3 d6 6.0-0 0-0 7.a4 a6 Quite a popular choice by many top players. 5...h6 6.Bh4 d6 7.0-0 a5 8.c3 Ba7 9.a4 This was the first new move for me. White can play either 9.Re1 or 9. Nbd2 which would transpose to a variation I looked at. g5 10.Bg3 Ne7 I quite liked the idea as White is not able to play d4 as he pawn on e4 is hanging. Having the knight on g6 helps to launch the attack on White's king. 11.Qb3?! Forcing me to play 0-0. I was suprised by this decision as I would have played 0-0 in any case. After Qb3, I am able to play ...Nh5 without any issue. 0-0 12.Nbd2 Ng6 13.d4 Nh5 14.dxe5? A serious error. Even though White has wasted a couple of moves in the opening, ot is the d4 pawn which restricts the activity of my bishop on a7. 14.Kh1!? The idea of Kh1 is to reroute the knight via g1 and e2. Sacrificing the d4 pawn is not a big issue as White would be able to generate a lot of counterplay. Qf6 Of course I would not take the pawn on d4. 14...g4 15.Ng1 exd4 16.cxd4 Bxd4 17.Ne2 15.Rad1 Kg7 14...Nxg3 14...g4! This is more precise as it forces White's knight to retreat to the unpleasant e1 square. 15.Ne1 Nxg3 16.hxg3 dxe5 17.Rd1 h5-+ White is totally lost here thanks to the bishop on a7 and the advancement of g and h pawns. 15.hxg3 dxe5 16.Rad1 g4 17.Nh2 Qg5 17...Qf6! prevents the white rook on f1 from moving. White's knight is also stuck on h2 as the square on f1 is occupied by rook. 18.Rfe1 Kg7 19.Re2 h5 20.Ndf1 h4 21.Rd3 After this move the game is over. 21.gxh4 This move puts up lot of resistance and Black is only marginally better. Qxh4 22.g3 This move might have skipped Nodirbek's attention. It is unusual to give away the g3 square which is usually occupied by the knight. It is slightly scary for White in view of a possible black trippling on the h-file and delivering a checkmate. In fact White has pretty good counterplay on the d-file. Qg5 21...hxg3 22.Rxg3 22.Nxg3 Nf4-+ 22...Nf4 23.Nxg4 Bxg4 24.Ne3 Bxe3 25.Rexe3 Ng6 Here 25...Kf6 and 25...Kh8 are winning as well. I simply decided to safeguard my king and continue the attack on the h-file by bringing both my rooks. 26.Be2 Be6 27.Qb5 Qf4 Protecting the e5 pawn. 27...Qf6 28.Ref3∞ 28.Qc5 Rh8 29.Qxc7 Rh6 30.Bf3 Rc8 31.Qxa5 Rch8 32.Kf1 Rh1+ 33.Ke2 Bc4+ 34.Kd2 Rf1 I was quite happy to win against Nodirbek in such a fashion. We managed to hold the match against the young Uzbekistan team who went on to win the gold medal at the chess olympiad. 0–1

Abdusattorov,N2688Harikrishna,P27200–12022C50Olympiad-44

 

It’s to the credit of the Uzbek Team that it remained in the race for the first place till it faced "India II" Team in the penultimate round.  Here unfortunately, Sindarov lost to Praggnandhaa and games on other boards were drawn. So only the first board encounter, Abdusattorov-Gukesh remained and it was watched with bated breath by spectators all over the world. Before this round Gukesh rode at wave with (+7,- 0, =1)) vanquishing Shirov, Caruana and Sargissian among others. But anything could happen in a game and coaches, R.B. Ramesh and Ivan Sokolov were understandably anxious.

1.d4 Nf6 2.c4 e6 3.Nf3 d5 4.Nc3 Bb4 5.Qa4+ Nc6 6.e3 0-0 7.Bd2 a5 8.a3 Bxc3 9.Bxc3 Ne7 10.Qc2 b6 11.b3 Ba6 12.a4 Ne4 13.Bb2 Nc6 14.Ba3 Nb4 15.Bxb4 axb4 16.Bd3 Nf6 17.0-0 c5 18.dxc5 bxc5 19.e4 dxe4 20.Bxe4 Ra7 21.Ne5 Qd6 22.Rfe1 Nxe4 23.Qxe4 Rd8 24.Qf3 Qc7 25.Rad1 Raa8 26.Rxd8+ Rxd8 27.Rd1 Rc8 28.Qg3 h5 29.h3 Rd8 30.Rxd8+ Qxd8 31.Nd3 h4 32.Qe3 Bb7 33.f3 Qd6 34.Kf1 e5 35.Nxc5 Bc8 36.Ke1 Bf5 37.a5 Qc7 38.a6 Bc8 39.Nd3 Bxa6 40.Qxe5 Qb6 Time control has been reached. White played an excellent technical game and has an easily won position. He is a pawn up and has positional domination. To compound the damage, two games were drawn, while Sindarov had a losing endgame vs Pragg. Needless to say our chances to survive the match (at this moment) I rated below zero! 41.Nc5 Qa5 42.Kd1 This does not throw away anything, but it's the start of a wrong plan. It's important to mention that White does not have an immediate win with 42.Qe8+ Kh7 43.Qe4+ Kg8 44.Qa8+ Kh7 45.Nxa6?? as Black starts checking with Qa1+= and saves a draw. In my opinion the easiest plan was to hide the king from checks. 42.Kf2! Qb6 43.Kg1 Qh6 44.Kh2+- and White wins. 42...Qd8+ 43.Kc2 Bc8 44.Ne4 Be6 45.Kb2 Qa8! Creating counterplay. 46.Nc5 Qa3+ 47.Kb1 g6!= Black is no longer worse and should save the game! 48.Kc2 Qa2+ 49.Qb2 Bf5+ 50.Ne4 Qa7 51.Kd3 Qg1 White cannot make progress. I was happy that Nodirbek had saved the game ... but in essence much did not change as Sindarov had lost to Pragg and we were losing the match ... 52.Qc2 Qc5 53.Qd2 Qg1 54.Kc2 Qa1 55.Kd3 Qg1 56.Qe2 Qa7 Honestly, I expected a draw agreement. Gukesh was running low on time, it's obvious that he has ruined his advantage, a draw is enough for India to win the match ... Unfortunately for Nodirbek he cannot play for a win ... 57.Qe3? This does not lose the game, but psychologically, it's a huge blunder! The game is now double- edged, with Black having more time on his clock. Your computer engine would be still giving you 0-0 evaluation, but (in a higher sense) this decision was a losing blunder. Qa2 White now loses his pawn on g2, and the position is sharp. It's now easy to makea mistake and lose the game. 58.Kd4 Qxg2 59.Ng5 f6 60.Qe8+ Kg7 61.Qe7+ Kh6 62.Nf7+ Kh5 Now White can make a draw. 63.Kc5 Your computer engine would tell you, 63.Qe3! g5 64.Qe8 Bd7 65.Qh8+= (or even 65.Qe4) led to a level position. But Gukesh was in time trouble and in this kind of position all three results are possible. This time around I was convinced that Nodirbek would win and the match would be saved! 63...Qxf3 64.Qxf6 Qe3+ 65.Kxb4 Bxh3 66.Ne5 Qd2+ 67.Kb5 Bd7+ 68.Kc5? 68.Nxd7! Qxd7+ 69.Kb6 h3 70.c5= Here my engine gives 0-0 evaluation. But in human play it's is still easy to go wrong ... 68...Qe3+ 69.Kb4 Bf5 70.Qh8+ Qh6 71.Qd8 Qg7 72.Nf3?? A blunder in a difficult position. Qb7+! and the match has been saved! 0–1

Gukesh,D2684Abdusattorov,N26880–12022D3844th Olympiad 2022

Now let me draw attention of the readers to a video that they have all seen before:

Gukesh was devastated by this loss, holding himself responsible for India’s descent down the Olympiad Cross-table.  In a subsequent interview he was to narrate how Anand spent time with him after this disaster, sharing his own experience of loss and defeat, bringing him back to his senses.

To return to the Olympiad, I have one reservation. The host nation is allowed to field two teams, a courtesy and privilege conferred by rules. This system gives unfair advantage to the host nation.  In the circumstances it’s a wonder that Uzbekistan survived its matches with Indian I and India II and went on to win Gold.

Anyway, the Ukraine Team won the Women’s Olympiad. Readers may recall that in the previous issue, CBM 209 ran a Special on Anna and Mariya Muzychuk from Ukraine. The sisters did their beleaguered nation proud by leading their team to victory. Both have annotated a game each.

As  Mariya Muzychuk  acknowledged, no less a role was played by their team mates,  especially, Anna Ushenina, 14th Women’s World Champion who scored 7.5 out of 9 points.

This issue also gives games from Sinquefield Cup including the well-known encounter, Carlsen –Niemann that led to the world champion’s exit from the tournament and the controversy that followed. Now that the matter is in court, let the law take its own course. One unfortunate outcome of the unsavoury development was that the rest of the tournament lost public interest. Not fair to the players, though.

Ding Liren : A star in waiting

This issue also carries a special feature on Ding Liren with 18 annotated games, commentary on his play in middlegame and endgame. The opponents include such illustrious names as, Aronian,  Caruana,Duda,  Mamedyarov and Nepomniachtchi.

1.d4 Nf6 2.c4 e6 3.Nf3 d5 4.Nc3 Be7 5.Bf4 0-0 6.e3 b6 At the time this game was played this variation had become very popular at the top level. 6...c5 and 6...Nbd7 are still more popular, but both moves were already heavily explored. 7.Bd3 The second most played. 7.cxd5 is the most popular, as well as a typical reaction to b7-b6 by Black. The drawback is that Nxd5! proved to be a reliable way of solving Black's opening problems in many games. White has many options to fight for an advantage: 7.Rc1 7.Be2 7.Qc2 7.a3 all these moves were seen in grandmaster practice. 7...dxc4 7...Bb7 is also possible. 8.cxd5!? can be played under better circumstances than in the previous move, although the position is very interesting and offers chances for both sides. 8.Bxc4 Ba6 This is Black's main idea: the exchange of bishops is a nice way of relieving his slightly cramped position. 8...Bb7 is a more fighting option, keeping more pieces on the board. 9.Bxa6 In an earlier round of the same tournament, 9.Qe2 was played by Carlsen. Still, after Bxc4 10.Qxc4 c5 11.dxc5 Bxc5 12.0-0 Qc8 13.Rfd1 Nbd7 Carlsen,M (2882)-Karjakin, S (2750) Sinquefield Cup 7th 2019 (5) 1/2-1/2 Black eventually was able to equalize. 9...Nxa6 10.Qe2 Qc8 11.0-0 Qb7 This was a new move introduced by Caruana. The direct 11...c5 is more often seen. I've faced this move once in a rapid game, which went 12.Rac1 12.e4!? has given some pressure for White in recent games. 12...Qb7 13.h3 Rfd8 14.Rfd1 Rac8 15.a3 h6 16.Nb5 Nd5 17.Bg3 cxd4! Quintiliano Pinto,R (2484)-Bindrich,F (2590) Wch Rapid Doha 2016 (3) 1/2-1/2 Finally, Black solves the problem of the knight on a6 and equalizes. 12.a3 with the very logical idea of cramping Black's queenside. c5 13.Nb5! I like this move, as the knight keeps an eye on the newly-weakened d6-square. 13.Rac1 would transpose to 11...c5, but as we shall see Ding has different plans for this rook in mind. Seizing space in the centre with 13.e4 was another option. However, after Rfd8 14.Rad1 cxd4 15.Nxd4 Rd7 Black seems fine. 13...Rac8 13...Ne4 Carlsen,M (2835) -Nakamura,H (2746) Wch Blitz St Petersburg 2018 (17) 1/2-1/2 was played by Nakamura in a blitz game. Although it worked well in practice, White's play can be improved by means of 14.Ne5! as in case of Nd6 this idea doesn't works so well as in the game: 15.Nxd6 Bxd6 16.Rfd1 Rfd8 17.dxc5!? Bxc5 17...Nxc5? loses material due to 18.Nxf7!+- 18.b4 Bf8 19.e4 when White's position still seems a bit easier. 13...cxd4 is a natural attempt of solving Black's problems by releasing the tension in the centre. 14.Nfxd4 Nd5 In case of 14...Rac8? there is the strong reply 15.Qf3! when the queen's exchange would lead to the loss of the a7-pawn. On the other hand, after Nd5 16.Nd6 Bxd6 17.Bxd6 Rfd8 18.Bg3± Black remains under unpleasant positional pressure. 15.Be5!? aiming to provoke further concessions on Black's camp. Nc5 16.Rac1 Rac8 17.b4 Nd7 18.Nd6! Bxd6 19.Bxd6 Rxc1 20.Rxc1 Rc8 21.Rc2 The position seems balanced. White still enjoys a bit more space and can try some ideas, like improving the structure in the centre by means of e4-f3 or to put some pressure on the queenside, but with correct play Black should be able to keep the control. 14.b4!? This interesting idea was the reason Ding preferred to keep his rook on a1. 14.Bd6 14.Rac1 14.Rfd1 14.Rad1 14.h3 all these moves are suggested by the engine, with a more or less balanced game. Nevertheless, Ding finds a creative way of forcing an unbalanced game and to try to pose practical problems for Black. 14...Nd5 After 14...cxb4? 15.axb4 White has an obviously unpleasant initiative. An important point is that Bxb4? loses on the spot in view of 16.Qa2 Nb8 17.Bd6!+- 15.bxc5 Another idea was 15.Bd6 when after Rfd8 16.Bxe7 Qxe7 17.e4 Nf4 18.Qe3 Ng6 19.e5 it seems that White has a pleasant advantage due to the beautiful outpost on d6 for the knight. Still, after cxb4 20.axb4 Nxb4 21.Rxa7 Rd7= Black also gets a strong knight in the centre, with a balanced game. 15...bxc5 The insertion of 15...Nxf4 16.exf4 bxc5 only gives more ideas for White, for example: 17.Rab1 Rb8 18.f5! and Black is already under unpleasant pressure. For example: Qd5 If 18...exf5?? 19.Nc3!+- Black loses a piece. 19.Nxa7 Rxb1 20.Rxb1 Nc7 21.Qe5! Qxe5 22.Nxe5 cxd4 23.a4 exf5 24.Nac6 and White keeps the better chances thanks to the distant passed pawn. 16.Rab1 This is a critical moment for Caruana, as White's initiative already seems very threatening. Rc6? This seems a natural way of neutralizing White's threats and to fight for the b-file, still it is the move that allows Ding to take the initiative. 16...Nxf4 17.exf4 transposes to the previous note. It's worth noting that the game's defensive idea Rc6 is tactically refuted now by means of 18.Ne5 Rb6 19.Nc4! Rxb5 20.Na5! Rxb1 21.Nxb7 Rxb7 22.Qxa6 when Black has a long and unpleasant defense ahead. 16...Nb6? 17.a4!± is also a difficult position for Black. 16...Qa8! was the right move to avoid problems. The best attempt for White now is 17.Bd6 17.Nd6? is bad in view of Nxf4 18.exf4 Bxd6 19.Qxa6 Bxf4 17.Be5 now can be met by cxd4 18.Nfxd4 Nc5= and Black is ok. 17...Rfd8 18.Bxe7 Black is also fine in case of 18.e4!? Bxd6 19.exd5 Qxd5 20.Nxa7 Rc7 21.Qxa6? Ra8 regaining the piece. 18...Nxe7 19.Rfc1 cxd4 20.exd4!? 20.Nfxd4 Nc5 is simply harmless for Black. 20...Nd5 21.Ne5 White is trying to keep some pressure, but with correct play Black is able to neutralize it: Nac7 But not 21...f6? 22.Nd3!± when Black has too many weak point in his camp. 22.Qf3 f6 23.Nxc7 Rxc7 24.Rxc7 Nxc7 25.Nc6 Re8 26.Rb7! Nd5! 27.Qb3 a6= and Black keeps the control, although he still needs to be a bit careful in the next moves. However, I think it's hard to criticize Caruana's move in the game. After all, it seems a very logical idea, and it wasn't easy to see that Black's position would become so unpleasant in advance. 17.Be5! Starting from this point, Ding makes a series of strong moves, exploiting Black's mistake in a very precise way and getting an easier game. The analysis shows that Ding was very aware of the subtleties hidden in the position. For instance, in case of the the less precise 17.Bg3?! Black is totally out of danger if we follow the same path as in the game: Rb6 18.a4 Nac7 19.dxc5 Bxc5 20.Rbc1 Nxb5 21.Rxc5 Nbc3! and the initiative is already with Black. This is why the bishop should go to e5. 17.Nd6? Qd7= is also harmless for Black now that the knight is defended on a6. 17...Rb6 17...Qa8!? still could be considered, but this time it wouldn't be enough to solve Black's problems. The position after 18.e4 Nf6 19.Bxf6 Bxf6 20.d5! exd5 21.exd5 Rb6 22.d6± is clearly better for White. 18.a4! Creating the obvious yet annoying threat a4-a5. Nac7 Black loses material in case of 18...cxd4? 19.Bxd4 Nc5 20.a5 Rc6 21.Ne5 Rcc8 22.Nd6+- 19.dxc5! Now Ding turns his attention to the c-file. Bxc5 20.Rbc1 Nxb5 21.Rxc5 Nd6 21...Nbc7?! seems even worse: 22.e4 Na6 23.Rcc1 Ndb4 24.Nd4 White has many annoying threats here. Nc6 seems a nice way of forcing exchanges, but after 25.Nxc6 Rxc6 26.Rxc6 Qxc6 White still has the strong idea 27.Qb5! when despite the material balance, Black is on the verge of collapsing. For example: Rc8 28.Bd4+- 22.a5 The pawn continues its annoying march. Rc6 23.Bxd6! The culmination of Ding's last moves, assuring he gets the control over the c-file.. The engine also likes White's position after 23.Rxc6 Qxc6 24.Nd4 Qd7 25.Rc1 Rc8 26.Rxc8+ Nxc8 27.Qg4 f6 28.Bg3 Kf7± but I think the game's continuation is much more unpleasant for Black in practice. 23...Rxd6 24.Rfc1± At a considerable depth, my engine evaluates the position as only slightly better for White. However, in practice things are considerably harder for Black. In first place, the pressure on the c-file forces Black's pieces to remain in the defensive, since the invasion of the white rooks could be decisive. By this reason, White has a lot more freedom to improve his pieces and think about active ideas, such as Nd4-c6(b5) or e3-e4 followed by Rc7. Such positions tend to be very unpleasant for the defending side, especially when you're facing a strong technical player like Ding, even when you are a great defender like Caruana. h6 25.h3 Both sides take a breath to take measure against back rank motifs. Rfd8 26.Ne5 Now it's time to advance. Nf6?! This allows Ding to improve his position further. Surprisingly, Überraschenderweise war 26...Ne7! was the right retreat. The analysis show that this move allows Black to keep the balance, but the lines don't look obvious to me: 27.Qh5 27.Rc7 is the most direct, but Black has the nice resource Rd1+ 28.Kh2 Qb8! keeping the control, for instance: 29.R1c4 R1d7!= 27.Rb5 Qa6 28.Rc7 also looks very strong for White. The right defence now is Rd1+ 29.Kh2 Qd6 30.Rxa7 Ng6! when after 31.Qh5 Nxe5 32.Qxe5 Qxe5+ 33.Rxe5 R8d2= the endgame is drawish. 27...Rf8 28.Rc7 Qb2 Although White's pressure seems always unpleasant, the following line shows that Black always has a move to keep the defence: 29.R1c5 g6! 30.Qf3 Rd5! 31.Nd7! Rxc5 32.Rxc5 Rd8 33.Ne5 Nf5 34.e4 Qd4! 35.Nxf7! Kxf7 36.Rc7+ Rd7 37.Rxd7+ Qxd7 38.exf5 exf5= This long variation illustrates how difficult is to defend in chess sometimes. Many of Black's moves were not so obvious and require a great precision to keep the game going on. It's also a nice example of how much easier is to find the moves for White. 27.Nc6 Maybe Caruana intended to meet 27.Rc7 with Rd1+ 28.Kh2 Qe4!? although after 29.Qb2! R1d2 30.R7c2 Rxc2 31.Rxc2± White keeps the advantage. 27...R8d7 28.a6!? When I was watching the game live, I remember of thinking this was a risky decision by Ding, in the sense that it would require a lot of precision to preserve White's advantage, since the pawn becomes vulnerable on a6 sometimes. As we will see, he has an active plan in mind. 28.R5c2!? was a nice alternative, preparing the same Ne5 idea seen in the game. On the other hand, the direct 28.Ne5 could be met by beantwortet werden durch Rd2! 29.Qc4 R7d5 and Black resists. An important detail is that 30.Rc7? Qb2 is already bad for White actually. 28...Qb6 Black could try 28...Qb3 29.Ne5 Rd1+ but the endgame after aber das Endspiel nach 30.Rxd1 Qxd1+ 31.Qxd1 Rxd1+ 32.Kh2 Ra1 33.Rc8+ Kh7 34.Nxf7 Rxa6 35.Rc7 still seems easier for White. 29.Ne5 Rd8 The engine shows a bizarre defense for Black here: 29...Rd1+ 30.Rxd1 Rxd1+ 31.Qxd1 Qxc5 32.Qd8+ and now Kh7! But not 32...Qf8? 33.Qc7+- 33.Nxf7 Kg6! when the king's activation suddenly gives Black enough counterplay to keep the balance. 30.Rc8! The point: Ding aims to transform his positional pressure into initiative. Qa5 Caruana, by his turn, tries to disturb White's strong coordination. 30...Rxc8? 31.Rxc8+ Rd8 would be very bad due to 32.Qc2! when White's pressure becomes overwhelming. For example: Rxc8 In case of 32...Qd6 White has the strong idea 33.Qc7! Qxc7 34.Rxc7+- with a winning endgame. 33.Qxc8+ Kh7 34.Nxf7 Qb1+ 35.Kh2 Qf5 36.f4! Ng4+ 37.hxg4 Qxf7+- and the endgame should be a technical win for White. 31.f4 A natural reaction, which nevertheless gives Black a chance of equalizing. According to the engine, the right path to keep White's advantage was 31.Qb2! Qxa6 32.Qb8 Qb6 33.Qa8!± but this seems a bit inhuman to me. 31...Rd2?! In difficult positions - and I assume with time trouble already present - even the best players can go wrong. Now Ding is back in the driver's seat. 31...Nd7! seems a bit strange, but it would have solved Caruana's problems. For example: 32.Rxd8+ 32.Nc6? Rxc8 is simply bad for White. 32...Qxd8 33.Nc6 Qb6! and White has problems to keep everyting under control. 34.Nd4 34.Ne7+ Kh7 35.Nc8 Qxa6! Black is safe thanks to this resource. 36.Qc2+ Rd3 37.Rd1 Nc5! 38.Nxa7 Qxa7 39.Rxd3 Nxd3 40.Qxd3+= 34...Qxa6 35.Qxa6 Rxa6 36.Rc8+ Kh7 37.Rc7 Rd6= 32.Qf3 32.Qf1! was more precise. The point is that R2d5? now can be met by 33.Nc6 Rxc8 34.Nxa5+- since the Rc1 is defended. 32...R2d5! Avoiding the invasion of the White queen. Black would be in a very difficult position after 32...Qxa6? 33.Qa8 Qa5 33...Rd1+? 34.Kh2+- is even worse. 33...Qb6? is refuted by 34.Nc4!+- 34.Qb7!± when White regains the pawn and keeps the attack, with a clear advantage. 33.R1c7 The most logical way of increasing the pressure. Another option was 33.Rxd8+ Rxd8 33...Qxd8 34.Rb1!+- seems very unpleasant for Black. 34.Qb7! Ding probably rejected this variation in view of Qd2! when Black achieves dangerous counterplay. White probably still has an advantage, but the position becomes more unstable and potentially risky. 33...Kh7! 34.Kh2! Both sides push their kings to safer places, as far as possible from the enemy pieces. After the hasty 34.Nxf7 Black gets enough counterplay by means of Rd1+ 35.Kh2 Qe1! 36.Rxd8 Qg1+ 37.Kg3 Qe1+= 34...Rxc8 35.Rxc8 Qxa6 According to the engine, Black is completely out of danger at this point. However, in practical terms we still have a fight on the board. 36.Ra8! Ding finds the best practical try. 36.Rc7 was more natural, attacking two pawns. Now Black could defend by means of Kg8!? 37.e4 37.Nxf7? is a mistake in view of Qb6! 38.Nxh6+ Kh7!-+ and Black wins. 37...Ra5 38.Nxf7 Ra3! 39.Qf2 Qd3 and Black has enough resources to keep the balance, for instance: 40.Qh4 Rc3! 41.Rxa7 Qe3! 42.Rb7 Rc1 36.Rf8 directly would be met by Nd7! when all the lines lead to a drawish ending: 37.Nxd7 Or 37.Qe4+ f5 38.Rxf5! Kg8! 39.Rh5 Nxe5 40.Rxe5 Rxe5= 37...Rxd7 38.Qe4+ f5 39.Rxf5! exf5 40.Qxf5+ Qg6 41.Qxd7 a5= The distant passed pawn gives Black enough counterplay, and the ending after 42.Qb5 Qe4 43.Qxa5 Qxe3= is likely a draw. 36...Qb7! Caruana is up to the task and also finds the best reply. There is no time to look for a counterattack with 36...Qa1? 37.Nxf7 Rd1 as Black loses first: 38.Rh8+ Kg6 39.Ne5+ Kf5 40.e4+ Nxe4 41.Rf8+ Nf6 42.g4# 37.Rf8! Regaining the pawn in a better version, as Black doesn't have the resource Nd7 now. Although the engine keeps saying the position is equal, I have no doubt that things look more tense and more unpleasant for Black, as White's initiative is still alive. Rb5? In a tense situation and after a tiring battle, Caruana makes a mistake. This time, Ding won't let it slip out. 37...Nd7?? obviously doesn't work now due to 38.Rxf7 Nxe5 39.Qe4++- To be fair, Black's path to the draw was very narrow and difficult. He had to start with 37...Qb4! forcing the rook to leave the 8th rank. Then 38.Rxf7 and only now Qb1‼ setting the counterplay. The main line still contains some fireworks, and forces Black to part with all his pieces except the queen: 39.Qg3 Nh5! 40.Qg4 Rd1! 41.Qxh5 Rh1+ 42.Kg3 Qe1+ 43.Kg4 Qe2+ 44.Kh4 Rxh3+! 45.gxh3 Qf2+ 46.Kg4 Qg2+ 47.Kh4 Qf2+= Indeed, chess is a very hard game. Sometimes we are too close, yet too far... In case of Im Falle von 37...Qb1? 38.Nxf7+- the white attack comes first. That's why it's so important to force White to capture with the rook on f7. 38.Qf1‼ A brilliant retreat. I wouldn't be surprised if Caruana simply missed this move, since queen's retreats are not so natural to consider. The queen does a wonderful job on f1 keeping an eye on both g2 and on the enemy rook, and getting ready to attack the black king from d3. Qd5 Caruana still try to defend by keeping the enemy queen under control, but his position is already very difficult. In case of 38...Rb2 White gets an important tempo as g2 is defended. 39.Nxf7 Qe4 40.Rh8+ Kg6 41.Ne5+ Kf5 and now 42.Nc4!+- forces Black to give an exchange, as there is no way to prevent the check on d6. 38...Rb1? would be even worse: 39.Qd3+ Qe4 40.Qd8+- with unavoidable mate to come. 39.Nxf7 Nd7 Otherwise the game would be quickly decided by Rh8 and Ne5. 40.Rd8 Rb8 Again the only move, in view of the threat of Ne5. 41.Rxb8 Nxb8 42.Qb1+ Qf5 43.Qb7! Of course not 43.Qxb8?? Qxf7= 43...Nc6 44.Nd6! Even in this simplified endgame, White still can play for the initiative. Qc5 44...Qd5? loses on the spot due to 45.Ne8!+- and there is no way to defend g7. 45.Ne4! Now 45.Ne8? is met by Ne7= 45...Qc2? The decisive mistake. Black's best chance was to look for chances in the endgame after 45...Qxe3 46.Qxc6 Qxf4+ 47.g3 Qe5 48.Kg2 when White will certainly try for a long time, but I think Black has decent practical chances. The distant passed pawn prevents White from achieving the ideal coordination of his pieces and it's not easy to find active ideas for White because the white king could be exposed to many checks. In any case, this definitely would have offered better chances than the game continuation. 46.Nf6+ Kg6 47.Ne8! Qc3 Caruana was likely counting on this move to keep everything defended. However, with his next move Ding poses new problems for Black: 48.e4! The advance e4-e5 basically decides the game, as after losing the g7-pawn Black's position quickly collapses. a5 49.Qd7! a nice touch of precision by the Chinese GM. 49.e5!? directly also wins, but Ding's move seems even simpler for me. Kf5!? maybe he didn't want to allow this king's running. Anyway, White also wins here: 50.Nd6+! Kxf4 51.Qf7+ Kxe5 52.Qxg7++- 49...a4 50.Qxe6+ Kh7 51.e5! Back to the mating ideas. Nd4 52.Qd7 Kg6 The desperate attempt 52...Nf3+ only gives a few checks for Black: 53.gxf3 Qc2+ 54.Kg3 Qg6+ 55.Kh4+- 53.Qxg7+ Kf5 The king runs anyway, but now Ding has got a powerful passed pawn on the e-file. 54.Nd6+ Kxf4 55.Qf6+ Ke3 56.e6 Kd3 57.e7 A great fight between two players who I've always admired and followed the games, as we have the same age. I find impressive how Caruana managed to hold the pressure and find the right moves in many difficult moments. That makes even more impressive that Ding was able to keep pressing for the whole game, always looking for moves which gave him practical chances and kept his opponent under pressure and busy with problems to solve. After all, this game shows how tough is to play chess at the top level, where a couple of mistakes at critical moments can be enough to decide the game. 1–0

Opening videos and surveys

There are 3 opening videos in this issue. The first offers an introduction to a new gambit in the English Opening by Daniel King.

1.c4 e5 2.Nc3 Nf6 3.Nf3 e4 4.Ng5 c6!?

Currently it has no proper name. As it was introduced by the Indian GM, Adhiban, it makes sense to call the line after him. Note that the game, Vakhidov-Adhiban, Chess Olympiad 2022 with the same line is also analysed by Ivan Sokolov, the coach of the Uzbekistan team. However, his analysis begins only after White is a healthy pawn up on the 23rd move.  No matter, Black was still able to draw with some dangerous counterplay. The second  presents  an analysis  of a line in the Modern Benoni by Mihail Marin. The third is a lecture on the Classical Variation of the Nimzo- Indian by Jan Werle.  Take your pick.

There are as many as 12 opening surveys ranging from the Sicilian to the semi Slav. Among them, I would single out two articles, one on the Dilworth Variation by Robert Ris and the other on the Botvinnik System by Evgeny Postny. Vernon Dilworth (1916-2004) a great chess amateur has not always received his due for his remarkable line in the Ruy Lopez. By way of historical interest here is the game in which it made its debut in correspondence chess. I have also provided an over view of the Open Spanish for readers not familiar with current theory.

1.e4 e5 2.Nf3 Nc6 3.Bb5 The Ruy Lopez or the Spanish is one of the oldest openings in chess. a6 4.Ba4 Nf6 5.0-0 Nxe4 The Open Spanish advocated by Dr. Tarrasch. In modern times Viktor Korchnoi was its greatest exponent. Currently Fabiano Caruana is its leading exponent and he has played it on both sides of the board. 5...Be7 6.Re1 b5 7.Bb3 d6 8.c3 is the standard line of Closed Spanish. 6.d4 b5 The Riga Variation runs 6...exd4 7.Re1 d5 8.Nxd4 Bd6!? 9.Nxc6 Bxh2+! 10.Kh1! 10.Kxh2? Qh4+ 11.Kg1 Qxf2+ 12.Kh2 Qh4+= only results in a draw with perpetual check. 10...Qh4 11.Rxe4+! dxe4 12.Qd8+ Qxd8 13.Nxd8+ Kxd8 14.Kxh2± White has two pieces for Black's rook and two pawns. Results have favoured White and the engine indicates a win for Whte in the long run. 7.Bb3 d5 If 7...exd4? 8.Re1 d5 9.Nc3! Be6 Not 9...dxc3?? 10.Bxd5+- 10.Nxe4 dxe4 11.Rxe4± 8.dxe5 Be6 Both the White pawn on e5 and the Black knight on e4 look menacing. However, they can be undermined and become a source of weakness rather than strength. For now Black has the freer position as White is yet to develop the pieces on the queenside. White can play Rd1 and exert pressure on Black's d-pawn and also open the queenside with a2-a4. 9.c3 9.Qe2 making room for Rd1 piling pressure on d5 is the Keres line. 9.Nbd2 Nc5 10.c3 d4 11.Ng5! Introduced by Igor Zaitsev and played by Karpov against Korchnoi in the World Championship 1978. The idea is also attributed to Tal. Qxg5 12.Qf3 0-0-0 Not 12...Kd7? 13.Bd5! Nxe5 14.Bxe6+ fxe6 15.Qxa8+- 13.Bxe6+ fxe6 14.Qxc6 Qxe5 15.b4 Qd5 16.Qxd5 exd5 17.bxc5 dxc3 18.Nb3 d4 19.Ba3 g6 20.Bb4 Bg7∞ 9...Bc5 10.Nbd2 0-0 11.Bc2 Nxf2!? The Dilworth Variation makes its debut. 11...Bf5 12.Nb3 Bg6 is standard. 11...f5 12.Nb3 Bb6 13.Nfd4 Nxd4 14.Nxd4 Bxd4 15.cxd4 and the ensuing complications have a chequered history with some of the greatest players participating, Botvinnik, Boleslavsky, Reshevsky, Smyslov and Tal to mention a few. 15.Qxd4 c5 16.Qd1 f4 17.f3 Ng3 18.Rf2 18.hxg3 fxg3 19.Qd3 Qh4 20.Qxh7+ Qxh7 21.Bxh7+ Kxh7 22.Bg5 18...Nh5∞ a quieter line. 15...f4 16.f3 Ng3 17.hxg3 fxg3 18.Qd3! Bf5 19.Qxf5 Rxf5 20.Bxf5 Qh4 21.Bh3 Qxd4+ 22.Kh1 Qxe5 23.Bd2 Qxb2 24.Bf4 d4 25.Bxg3 c5 26.Rae1 d3 27.Be6+ Kh8 28.Be5 All known so far according to theory and practice. Now the engine suggestion is Qa3! followed by ...c5-c4. The position still remains unclear. 12.Rxf2 f6 The pinned rook would not go away. Meanwhile this move opens up the f-file. Its drawback is that Black has only one centre pawn after White's next move. In the other line Black has two centre pawns joining the attack. 12...Bxf2+ 13.Kxf2 f6 14.Nf1 fxe5 15.Kg1 is currently in vogue. 13.exf6 Bxf2+ 14.Kxf2 Qxf6 Black has given up two pieces for the rook with powerful pressure on the f-file. If White can develop his own pieces on the queenside, he can meet Black on his own terms. 15.Nb3? White intends to offer more support for the knight on f3 by bringing the other knight to d4. However, the knight is needed on the kingside. 15.Nf1! Ne5 16.Be3 Rae8 is the modern line. 15...Ne5 16.Nbd4?? 16.Kg1! Rae8 17.Be3 Nxf3+ 18.Qxf3 Qxf3 19.gxf3 Rxf3 20.Bc5 Bh3 is preferable. 16...Bg4-+ 17.b4 This move prevents...c7-c5 that would have dislodged the knight. Rae8 17...Qb6! 18.Kg1 Nxf3+ 19.gxf3 Rxf3-+ is faster. 18.Bd3 18.Bb2 fails to Qg5 19.Qc1 18.Bd2 Qb6! 19.h3 Bxf3 20.gxf3 Nxf3 21.Kg2 Nxd4 22.cxd4 Qxd4 23.Kh1 Re5!-+ 18...Qh4+ Or 18...Nxf3 19.Nxf3 Qh4+ 20.Kg1 Bxf3 21.gxf3 Re1+-+ 19.Kg1 Nxd3 19...Nxf3+ 20.Nxf3 Bxf3 21.gxf3 Re1+-+ transposes to the previous line. 20.Bd2 If 20.Qxd3?? Re1+!-+ The attack on the king continues even after the exchange of queens. 20.Nxh4 Bxd1 21.Bd2 Rf2 22.Rxd1 Rxd2!-+ 20...Qf2+ 20...Qf2+ 21.Kh1 Rxf3 22.gxf3 Bxf3+ 0–1

The other article on the Botvinnik System offers analysis of a rare move 12.h4!? It’s a dangerous move as the pawn threatens to roll forward to h8. However, Black has to take strong measures to create counterplay.  Here is an illustration hidden in Evgeny Postny’s annotations:

An old  classic remembered

One more feature deserves  mention. It’s the commentary on the game, Fischer – Petrosian Candidates’ 1971 (7) by Dorian Rogozenco. It may be recalled that this game was also discussed in a recent article on the news page.

Besides opening surveys, this issue has standard features on tactics, strategy and the endgame. A new feature continued from CBM 208 is a video lecture on time management by Jan Markos. A practical lesson for serious tournament players.

Summing up

The main database of the issue has 7578 recent games of which 45 are deeply annotated. There is much else in this DVD that deserves to be explored. Apart from the GMs I have already mentioned, the commentators include Anish Giri, Ajun Erigaisi, Gabriel Sargissian,  Luke McShane,  Pragganandhaa,  and Wesley So among others.  A major contribution is made by Ivan Sokolov who has made a commentary on the decisive phase in 8 games. It may be noted that there are more annotated games in the sections on opening theory and training.

Well, practice makes perfect.
