CBM #203 Special: Ian Nepomniachtchi
1.e4 c5 2.Sf3 d6 3.d4 cxd4 4.Sxd4 Sf6 5.Sc3 a6 6.Tg1!?
This rare move became famous when Ivanchuk used it in a rapid game to defeat Kasparov. From all White's options this move is ranked 12th by number of games played, but it's certainly more dangerous as the current game proves.
6...b5 Another remarkable game in this line went 6...Sc6 7.g4 g6 8.g5 Sd7 9.h4 Sxd4 10.Dxd4 Se5 11.Kd1!? Van Foreest,J-Firouzja, Wijk aan Zee 2020.; Other critical options are the typical moves 6...e6; 6...e5; 6...g6
7.g4 Lb7 8.g5 8.Lg2 has been played more frequently, but that's not why Ian decided to give 6.?g1 a try!
8...Sxe4 Carlsen deviates from the previous game which went 8...Sfd7 9.a3 g6 10.h4 Lg7 11.h5 Sc6 12.Le3 Sc5 was seen in Nepomniachtchi-Carlsen, chess24.com 2020, and now strong would have been 13.h6! Lxd4 14.Lxd4 Sxd4 15.Dxd4 e5 16.De3 followed by 0–0–0. The pawns on g5 and h6 remain quite unpleasant even in the long run.
9.Sxe4 Lxe4 10.a4!?
A new idea which poses Black some serious practical problems. In previous games White exclusively opted for 10.Dg4
10...e5 One month after the present game the only other GM game saw 10...b4 which is at least a safer continuation for Black. 11.De2 d5 12.f3 Lg6 13.f4 e6 (13...Le4!?) 14.Le3 (14.f5?! Lc5! 15.fxg6 Lxd4 16.gxf7+ Kxf7?) 14...Ld6 15.h4 0–0 16.0–0–0 Sd7 (16...b3!) 17.h5 Le4 18.Lg2 Sc5 19.Lxe4 dxe4? (19...Sxe4!) 20.Kb1 Sxa4 21.f5 exf5 22.Sxf5 Sc3+ 23.bxc3 bxc3 24.Txd6 Tb8+ 25.Kc1 Da5 26.Sh6+ gxh6 27.gxh6+ Kh8 28.Dxa6 Db4 29.Tb6 1–0 Lagarde-Brunello, Trieste 2020.
11.axb5! Le7 The critical move is accepting the challenge with 11...exd4 12.Dxd4 d5 13.Tg3!? though it's understandable one isn't eager about entering this position as Black. For the piece, White has one pawn, ideas to regain the piece with ?e3 (pinning the bishop on e4), while it's not simple for Black completing development as the queen on d4 is eyeing the pawn on g7.
12.Tg4! axb5 12...Lg6 13.Lg2 d5 14.Le3! 0–0 (14...Lh5 allows 15.Sf5! Lxg4 16.Dxg4 0–0 17.Lxd5 and the rook is trapped.; 14...exd4 15.Txd4 0–0 16.Lxd5 and White will regain the material with interest.) 15.Se2 is great for White.; 12...Lb7 13.Sf5 0–0 14.Tga4! and White obtains a very annoying pawn on a6.; 12...d5 allows 13.Txe4! dxe4 14.Sf5 Dxd1+ 15.Kxd1 when Black is still in deep trouble.
13.Lxb5+ Sd7 In hindsight, 13...Kf8 is the best option for Black, though also in that case after 14.Ld2 White retains the better prospects.
14.Ld2!
A great move, which forces Black to take a decision about his bishop on e4. 14.Txa8 Dxa8?; 14.Txe4? Txa1–+
14...Lb7 If Black intends to retain control over the f5–square with 14...Lg6 then White obtains a totally dominant position after 15.Sc6 Dc8 16.Txa8 Dxa8 17.Ta4 Db7 18.Dg4 followed by ?a7; Black is busted.
15.Sf5 0–0 16.Txa8?! Ian is naturally playing for a mating attack and I doubt many people would have considered shifting play to the queenside with 16.Tga4!! when surprisingly Black's position is already collapsing as too many vulnerable points in his position require protection, e.g. 16...Sb6 (16...Txa4 17.Txa4 and Black is unable stopping both threats Ra7 and Ba5.) 17.Txa8 Lxa8 (17...Sxa8 18.Ta7 wins a piece.) 18.Lb4 Sd5 (18...Lxg5 19.Dxd6+–) 19.Txa8! Dxa8 20.Dxd5 Dxd5 21.Sxe7+ Kh8 22.Sxd5+–
16...Lxa8
17.Th4 With the idea of Qh5.
17...g6! The only move, as 17...Lxg5? 18.Lxg5 Dxg5 19.Lxd7 Dg1+ 20.Kd2 (20.Ke2?? Lf3+!) 20...Dxf2+ 21.De2 is just an extra piece for White.
18.Dg4 Sc5 18...gxf5 19.Dh5 leads to mate.
19.Dh3? Again, the most natural option chosen by Nepo is not White's best! The incredible 19.Kf1!! with the idea to prepare ?a5 wins for White after 19...Le4 (19...h5 is met by 20.Txh5! gxh5 21.Dxh5 Se4 22.La5!+–) 20.La5!! Lxf5 (Relatively best, since after 20...Dxa5 21.Sxe7+ Kg7 White gives mate by force 22.Txh7+ Kxh7 23.Dh4+ Kg7 24.Dh6#) 21.Lxd8 Lxg4 22.Lxe7 Tb8 23.Txg4 Txb5 24.Lxd6 Se6 25.Ta4 and the remaining endgame is pretty hopeless for Black, e.g 25...Sxg5 26.c4! and now 26...Txb2 27.Ta8+ Kg7 28.Lxe5+ even drops the rook.; 19.La5? simply fails now to 19...Dxa5+! check!
19...h5?
After this blunder it's game over, but probably the World Champion already didn't really like his position anyway, which may explain the reason he didn't go for the critical 19...Lxg5! 20.Txh7 Lxd2+! (20...Lf6? 21.Sh6+! Kxh7 22.Sxf7+ and White wins the queen.) 21.Kxd2 Dg5+ when the variations are becoming pretty insane, but certainly worth playing through! (21...gxf5? 22.Th8+ Kg7 23.Dh6#) 22.Kc3 (22.Kd1? is simply bad, on account of 22...gxf5 23.Th8+ Kg7 24.Dh7+ Kf6 25.Txf8 Lf3+! 26.Le2 Dg1+ 27.Kd2 Se4+ 28.Kd3 Lxe2+ 29.Kxe2 Dxf2+ 30.Kd3 Dd4+ 31.Ke2 Dd2+ 32.Kf1 Df2#; 22.Se3?! is an interesting alternative, though after 22...Se4+ 23.Kc1 Sxf2 24.Th8+ Kg7 25.Dh7+ Kf6 26.Txf8 Dxe3+ 27.Kb1 Ld5! only Black can be better.) 22...Se4+! (22...gxf5? 23.Th8+ Kg7 24.Dh7+ Kf6 25.Txf8 Se4+ 26.Kb3 Ld5+ 27.c4 and there no more any good checks as the black queen fails to join the counterattack against the white king.) 23.Kb4! - Robert Ris führt hiezu in CBM #203 eine Detailanalyse mit mehreren Untervariaten aus.
20.Txh5 gxh5 21.Dxh5 Se6 Withthout waiting for his opponent to execute the mating variation, the World Champion resigned, in view of 22.g6! fxg6 23.Dxg6+ Kh8 24.Dh6+ Kg8 25.Dxe6+ Kh8 (25...Tf7 26.Sh6+) 26.Dh6+ Kg8 27.Dg7# A wonderful prelude to their upcoming World Championship match in Dubai, November 2021!
1–0
