As I write these lines, the Candidates’ Tournament has drawn to a tumultuous close. Fabiano Caruana has deservedly emerged as the Challenger. It is only appropriate that the review of this issue should begin with a game by him.

Readers may recall, Nepomniachtchi was leading in the London Chess Classic last year. With a last-minute sprint, Fabiano finished with the same number of points as Ian and the two had to play a blitz match to resolve the tie. This issue of ChessBase Magazine includes all games from the tournament and I found the mini-match very interesting. Soon after the tournament, Caruana was interviewed by ChessBase and Fabiano’s response was revealing, both for his modesty and candour.

1.e4 c5 2.Nf3 d6 3.Bb5+ These Anti-Sicilian systems are a pain for Black players who prefer standard lines like the Najdorf. Bd7 3...Nd7 4.d4 cxd4 5.Qxd4 a6 6.Be2 Ngf6 7.0-0 Qc7 is also played here. 4.a4 An idea of Bent Larsen who loved to move rook pawns After 4.Bxd7+ Nxd7 is a popular reply. So is 4...Qxd7 that gives the knight the option of coming to c6. 4...Nc6 4...Nf6 is more usual. 5.0-0 g6 6.c3 6.Nc3 Bg7 is another line. 6...Nf6 7.d4 cxd4 not 7...Nxe4?! 8.Re1 Nf6 9.d5 Na5 10.Na3 Bxb5 11.axb5± 8.cxd4 Bg7 9.Nc3 0-0 10.h3 preventing...Ng4 so that play Be3 a6 11.Bc4 Rc8 12.Re1 12.Qe2 with the idea of Rd1 followed by e4-e5 is perhaps a better idea. After Qc7 the position is level. not 12...Qb6? 13.e5 Nh5 14.Rd1± 12...Ne8?! This move disrupts the co-ordination of pieces on the back ranks. What is more, it takes quite some time to acivate the knight. Instead Black can play the sober 12...Qc7 neutralising the threat of e4-e5. 13.Bd3 would have prevented counterplay with ...b7-b5. 13.Bb3 Na5 14.Ba2 In retrospect it appears that the bishop should have been placed on 14.Bc2 14...Nc4 15.Qd3 b5 sacrificing the b-pawn in search of counterplay 16.axb5 axb5 17.b3 Na5 18.Nxb5 White is a pawn up, but the fledgling on b3 is too weak. What is more, the bishop on a2 is awkwardly placed. Qb6 19.Na3 Nc6 20.Nc2 The knight hopes to reach d5 via e3. Unfortunately, he is never able to make it. 20.Nc4 preparing e4-e5 was good enough. 20...Nc7 crawling back to activity 21.Be3 A necessity. 21.Bb2 leaving e3 free for the knight does not work on account of d5! 21...Qb5! 22.Qd2 After 22.Qxb5 Nxb5 the knight becomes a force to reckon with. If 23.Rad1 Nc3 22...d5 23.e5 Bf5 24.Rec1 White has other ways of freeing his queenside. But not everything works. The advance 24.b4? costs the pawn his life. Bxc2 25.Qxc2 Nxb4 The problem with 24.Na3 is that the knight has no prospects on the queenside after Qb4 24.Rac1 deserves attention, after Ra8 25.Bb1 Ne6 Black is going to try and free his bishop on g7. 25...Qxb3? 26.Na1 Rxa1 27.Bxf5 Rxc1 28.Rxc1± 24...Ne6 25.Nce1 preparing to play Nh2 followed by N(e1)f3 and Ng4 Be4 25...f6 appears tempting. But Black has to be mindful of his d-pawn becoming a target after the advance, b2-b4. 25...Nb4 26.Bb1 Be4 transposes to the game continuation. 26.Nh2 Nb4 27.Rxc8 Rxc8 28.Bb1 h5 Bullet for bullet. White has not allowed...Nd3. In turn Black is not going to allow Ng4. 29.Nhf3 Nc6 30.Bc2 Bxc2 An impercetible error. The exchange of bishops simplifies the position and helps White. 30...Kh7!? deserves attention. If 31.Ng5+? 31.Rc1 is preferable. 31...Nxg5 32.Bxg5 Nxd4! 33.Qxd4 Bxc2 34.Bxe7 Be4 White is still a little better, however, Black pieces have become active. 31.Qxc2 Rb8 32.Nd3 Bf8 33.Rb1 Ng7 34.Nc5 Nf5 If 34...e6 35.Nd7 Rc8 36.Nf6+± 35.e6! Bg7 36.exf7+ Kxf7 37.Nd7‼ "A star move"-Seirawan. Caruana, however, was modest about it, "A standard tactic. I thought may be he had misssed Qxc6 and then comes Ne5." Ncxd4!? Desperate situations demand desperate remedies. But is this the right one? 37...Rd8? would have revealed the point of White's combination. 38.Qxc6! Qxc6 39.Nde5+ Bxe5 40.Nxe5+ Ke6 41.Nxc6+- A tougher defence is 37...Rc8 38.Rc1 Bf6 39.g4 hxg4 40.hxg4 Nd6 though this should also lose in the long run. 38.Nde5+ Bxe5 39.Nxe5+ White is threatening 40.Bxd4 Nxd4 41.Qxg6+ Ke6 40.Bxd4 Nxd4 41.Qxg6+ Kxe5 42.Re1+ Ne2+ 43.Kf1!+- The point. Now the knight is lost. Kd4 44.Rxe2 e5 Admirable courage! The king and and the humble pawns march even as the rook and the queen await orders. He cannot get the rook into play with 44...Rc8 45.Qg7+ Kc5 or 45...Kd3 46.Qg3+ Kd4 47.Qe3# 46.Qc3++- 45.Qg3 e4 46.Qe3+ Ke5 47.Kg1 Freeing the rook and ready to move to h2 in case of checks on the back rank. Now White threatens both f2-f3 and also Qg5+ winning the pawn. Qxb3 47...d4?? 48.Qxe4++- 48.Qg5+ Ke6 49.Qg6+ Kd7 50.Rd2 h4 51.Qf5+ Kc6 52.Qf6+ Kc5 53.Qd4+ Gaining time on the clock. Otherwise 53.Qxh4+- was available. 53...Kc6 54.Qf6+ Kc5 55.Qxh4 Rb7 Covering the second rank against queen checks. 56.Qd8 Rb6 57.Qc7+ Rc6 58.Qa5+ Kd6 59.Qd8+ Kc5 All of it played in fierce time scramble by both sides. 60.h4! Finally, White produces his trump card. e3? "I panicked a bit when I saw this move"-Caruana. But everything is in order. 61.Qe7+ 61.fxe3 Qxe3+ 62.Rf2 Qe1+ 63.Rf1 Qe3+ 64.Kh1+- also looks good. 61...Kb5 62.Qb7+ This gives Black a few chances and complicates the task. 62.Qxe3 Rc1+ 63.Kh2 Qxe3 64.fxe3+- is good enough. 62...Rb6 63.Rxd5+ Kc4 64.Qf7 exf2+! 65.Kxf2 He is not going to fall for 65.Qxf2?? Kxd5-+ 65...Qb2+ 66.Rd2+! An admirable finish. 1–0

Caruana,F2799Nepomniachtchi,I27291–02017B529th London Classic TB4

A terrific encounter in which the loser deserves as much credit as the winnner. One can only admire the fighting spirit of the Black monarch who marched through enemy territory (with two pawns for company) under a hail of bullets. "Nepo’s" admirers can also check out his annotations to his win over Anand in this issue.

Magnus suffered in this tournament, though he still managed to beat Adams and Aronian in the end. As noteworthy is his fighting draw with Nakamura. The game is annotated by Yermolinsky and also commented on in a video by Daniel King.


Play like Carlsen, avoid theory but without being passive or losing the initiative.


Azeris conquer Europe!

This issue also includes games from European Team Championship (won by Azerbaijan ahead of Russia and Ukraine) FIDE Grand Prix Palma 2017 (won by Aronian with Jakovenko and Nakamura following behind) and the Russian Championship (won by Svidler for the record eighth time). From the sporting point of view, the Azeri victory at the European Team Championship is perhaps the most important event reported in this issue. Few expected the Azeris to recover from the disastrous match with Italy when they were taken down with the score of 1½:2½. That defeat spurred them on to fight with fierce determination round after round. The turning point came in the decisive duel with Russia in the penultimate round. Here they beat their rivals with the score of 3-1. Mamedyarov prevailed over Grischuk and Radjabov downed Nepomniachtchi. There still remained the last round and they sailed through with an even score, 2:2 against Ukraine. At last, they had made it.

Among all the games I found the Grischuk-Mamedyarov encounter very fascinating. In this issue, it is annotated by Mihail Marin. Meanwhile, I happened to find a commentary on the game by Mamedyarov himself in “64 Review”, not to mention analysis by Anish Giri in “New in Chess” Magazine. I have made judicious use of all the three here.

1.e4 e5 2.Nf3 Nc6 3.Bb5 a6 4.Ba4 d6 The Steinitz Defence Deferred 5.0-0 Bd7 6.Re1 g5!? An extravagant move, but not without logic as Marin puts it. Among other things it undermines the knight's position, disrupting White's development. Black has other options, 6...g6 followed by...Bg7 or 6...Nge7 and the more conservative 6...Nf6 7.Bxc6 7.h3 only allows h5 -Mamedyarov If 7.d3 g4 8.Nfd2 h5 -Mamedyarov again 7...bxc6 7...Bxc6 was seen in the stem game half a century ago! More about it in the next game-NSH 8.d4 g4 9.Nfd2 exd4 10.Nb3 Ne7! If 10...Bg7? 11.Bf4 and White prepares e4-e5 advance. 11.Nxd4 Now 11.Bf4 is met by Ng6 as rightly pointed out by Mamedyarov. 11...Bg7 12.Nc3N The tempting 12.Nf5 Nxf5 13.exf5+ Kf8 14.Qxg4 h5 15.Qf3 Qf6 seen in Chen-Dai, Shanghai 2017 favours Black. While the king is displaced, his superior development tells. 12...0-0 13.Bg5?! This move only helps Black to mobilize his forces. 13.Be3 preparing to play Qd2 and Bh6 or briniging him to d4 challenging the power of the g7 bishop makes more sense. 13...f6! clearing the e8-h5 diagonal "with gain of time"-Marin 14.Be3 In "New in Chess" Magzine Anish Giri recommends 14.Bf4 followed by Qd2. 14...Qe8! 15.Qd3? The queen can do precious little here. 15.Qd2 is more to the point. 15...Qf7 Black prepares ...f5. 16.Qd2 Qg6 Of course not allowing 17.Bh6 17.Bf4 Anish Giri suggests the sensible 17.f3! with a lifeline on the second rank. 17...h5 18.b4 18.f3! was still available-Giri 18...h4 19.a4 Qh5! 20.Be3 "Anticipating...Ng6" Marin White could have tried 20.Rab1 Ng6 21.Nce2 not 21.b5?? Nxf4 22.Qxf4 Bh6-+ 21...f5∞ -Mamedyarov. However, Black's position still looks menacing-NSH 20...h3 21.Nce2 21.g3?! f5 22.exf5 Nxf5 23.Nxf5 Qxf5 24.Bf4 Rae8 25.Rad1 d5 21...hxg2 22.Nf4 Qh7?! Sacrificing the exchange. But was it necessary? 22...Qf7! preventing the invasion of White knights on e6 was strong enough. Now 23.Nxg2 is met by f5 23.Nfe6 Bxe6 He could still avoid the sacrifice of the exchange with 23...Rf7 24.Nxc7 Rc8 25.Nxa6 Ng6 according to Marin. 24.Nxe6 Ng6 25.Nxf8 Rxf8 26.Bf4 26.Kxg2?? Qh3+ 27.Kh1 Qf3+ 28.Kg1 Nh4-+ Marin and Giri recommend 26.Ra3! f5 27.Bd4 f4 28.Bxg7 Qxg7 29.f3!∞ 26...f5 27.exf5 Sadly, it's too late for 27.Ra3 now. fxe4 28.Bg3 Ne5+- 27...Nh4 28.Ra3 After 28.Qd3 Bxa1 29.Rxa1 Nf3+ 30.Kxg2 Rf6! Not 30...Qh3+? 31.Kh1 Rf6 32.Qxa6 -Mamedyarov 31.Qe4 31.Qxa6? Qxf5-+ Mamedyarov again 31...Kf8! 32.Bg3 Qh3+ 33.Kh1 Rh6 34.Qf4 Black has to find a way of getting his rook to e1. Rh7! 35.f6 Rh5! 36.f7 36.Qe4?? allows Qxh2+ 37.Bxh2 Rxh2# -NSH 36...Rh6!-+ There is no way of stopping ...Re6-Re1+and Qg2 mate (Giri) not 36...Re5? 37.Qf6! 28...Qxf5 29.Bg5 Nf3+ 30.Rxf3 gxf3 31.Bh6 Qd5?! By now Grischuk was in serious time trouble and Mamedyarov trips up in rushing him. He points out that he missed 31...Qf6! If 32.Bg5 Qg6 33.Bf4 Re8 34.Re3 Re4!-+ -NSH 32.Qc1? The last mistake. 32.Qe3! Kh7! A modest move compelling the exchange of bishops. 33.Bxg7 33.Bg5 Rf5 34.Bf4 Qc4-+ 33...Kxg7 34.Qe7+ Rf7 -NSH 32...Bc3 33.Re3 33.Rd1 Qh5 with the threat of...Be5 would force the exchange of queens and a lost ending for White. 33...Bd4 34.Rd3 Re8 35.c3 35.Be3 loses to Bxe3-+ 35...Bxf2+! 36.Kxf2 Re2+ and a despairing Grischuk resigned.

Grischuk,A2785Mamedyarov,S27910–12017C7221st European Teams8.1

The rivals spent quite some time analysing the lines after the game. At the board, it was not easy for Grischuk to find his bearings through a hurricane of complications.

The line was seen 50 years before!

In the analysis of this game, Marin mentions that it was Lajos Portisch who first played this line.

When I checked MegaBase I found, it was played way back in 1968 in Wijk aan Zee. The Hungarian veteran won it against Korchnoi who went on to win the tournament.

1.e4 It's unusual for Korchnoi to open with the king pawn. It was probably to sidestep the opening preparation of his opponent. e5 2.Nf3 Nc6 3.Bb5 a6 The old Steinitz Defence 3...d6 is met by 4.d4 Bd7 5.Nc3 Nf6 6.Bxc6 Bxc6 7.Qd3 with a superior position for White according to Portisch. 4.Ba4 d6 The Steinitz Defence Deferred, a great favourite of Paul Keres. 5.0-0 Every schoolboy knows the Noah's Ark Trap: 5.d4?! b5 6.Bb3 Nxd4 7.Nxd4 exd4 8.Qxd4?? 8.c3 dxc3 9.Nxc3 offers a little compensation for the pawn. 8...c5 9.Qd5 Be6 10.Qc6+ Bd7 11.Qd5 c4-+ 5.c3 f5 leads to the dangerous Siesta Variation, a line once favoured by Capablanca himself. 5...Bd7 5...Bg4 6.h3 h5 is a fun line that was once extensively analysed. However, after 7.Bxc6+ 7.d4 b5 8.Bb3 Nxd4 9.hxg4 hxg4 10.Ng5 Nh6∞ leads to terrific complications. 7...bxc6 8.d4 Bxf3 9.Qxf3 exd4 10.Rd1 results have been good for White. 6.Re1 g5!? It is incredible that Portisch, a player in the classical mould should be initiating this move. 7.d4 g4 8.Bxc6 Bxc6 A recent encounter saw 8...bxc6 9.Nfd2 exd4 10.Nb3 Ne7 and Black won in the game, Grischuk-Mamedyarov, European Team Championship 2017. 9.Nfd2 Qh4!? In his notes to the Informator Portisch recommended 9...h5 Both lines need more tests over the board. 10.Nc4 Bg7 11.dxe5 dxe5 12.Nc3 The aggressive 12.Na5 is met by Ne7 Now 13.Nxc6 Nxc6 would only ease Black's position a bit. 12...Rd8 13.Nd5?? A terrible blunder. 13.Qe2 would have assured him of a better position. 13...Bxd5 14.exd5 g3!-+ The point. White loses a piece. 15.hxg3 Qxc4 16.b3 Qxd5 17.Qg4 Bf6 18.Ba3 Ne7 19.Re4 Qe6 20.Qf3 0-0 21.Rae1 Bg7 22.Rh4 Ng6! obvious, nevertheless a beautiful move 23.Rc4 Rfe8 24.Qxb7 If 24.Rxc7 b5 25.Rc6 Qd7 26.Rxa6 e4-+ 24...Rd7 25.Rc6 Or 25.Rxc7 Rxc7 26.Qxc7 Rc8-+ 25...Qf5 26.Bc1 Necessary to prevent invasion of the second rank with....Rd2. If 26.Bb2 Rd2 27.Rf1 Red8 28.Qxa6 e4 29.Bxg7 Kxg7 30.Rxc7 Ne5-+ 26...e4 27.Qxa6 Ne5 28.Rc3 Ng4 29.Rf3! A neat attempt to defend the kingside that sadly comes to nought. Qh5 30.Rf4 Qh2+ 31.Kf1 e3 32.Bxe3 32.Rxg4? loses to e2+!-+ as pointed out by Portisch. 32...Qh1+ and Korchnoi resigned in view of 33.Ke2 Rxe3+ 34.fxe3 Qxg2+ 35.Rf2 Qxf2# 0–1

Kortschnoj,V-Portisch,L-0–11968C72Wijk aan Zee

In retrospect, this is a game in which Korchnoi would have preferred to play Black. This is how the old Viktor used to catch his opponents off guard in the middlegame.

As for Portisch, although he won the game, he was far from happy with his innovation and concluded, White was better. He never played it again. So it is to the credit of Mamedyarov that he revived it when everything was at stake.

To return to this magazine, there are as many as twelve opening surveys ranging from the Sicilian to the Catalan. Among them, Robert Ris’ treatment of the Benko Gambit and Evgeny Postny’s analysis of a rare line in the Reti deserve special mention.

How to beat Magnus  

Apart from these surveys, there are regular sections on opening traps, middlegame tactics and endings.There is much else in this DVD that deserves to be explored. In all, there are 1768 OTB games of which 157 are annotated. Among them, Anand’s analysis of his win over Carlsen in the World Rapid Championship* deserves special mention. I am sure, both Carlsen and Caruana would take a look at that analysis now that the world championship is due. Other annotators in the current issue include Radjabov, Wesley So and Bologan, to mention a few. A major contribution is made by Alexander Yermolinsky who has annotated 24 games. He is followed by Daniel Fernandez with 20 games.

Recommended.

* The rest of the games from the World Rapid and the World Blitz Championship are included in the next issue, CBM 182 Extra.


Enjoy the best moments of recent top tournaments (London, Grand Prix Palma, European Teams) with analysis of top players. In addition you'll get lots of training material. For example 12 new suggestions for your opening repertoire.
