Chess960: Nakamura flags Carlsen to keep match close

by Macauley Peterson
2/13/2018 – In a truly bizarre turn of events, Magnus Carlsen turned a match that should have been all but over into an exciting blitz battle on the final day, with Nakamura just two points behind. The World Champion literally threw away a half point, evidently disgusted that he did not manage to convert his clearly winning position earlier. One of the stranger spectacles you will ever see. Both games are analysed by GM Daniel Fernandez. Eight blitz games are played Tuesday beginning at 17:00 CET (11:00 AM EST). | Photo: Maria Emelianova / chess.com

Nakamura's new lease on life

After losing game seven, and trailing 9 : 5, Hikaru Nakamura was in a must win situation if he had any hope to close the gap in the blitz session, where wins only count for one point. But as game eight unfolded, that looked increasingly unlikely. Magnus was in the driver's seat and commentators Yasser Seirawan and Anna Rudolf were predicting almost certain defeat for the American.

Yet, as the second time control ticked by, the players traded down into a rook-and-bishop-versus-rook ending which is notoriously difficult to win, even with ample time on the clock. Carlsen was trying to do it with under two minutes on his. Nakamura kept moving quickly, until at some point everyone thought that surely Magnus would give up and offer a draw. There was just no time left to keep playing. Amazingly he continued moving and as his clock approached zero both players heartrates spiked — Magnus' pulse was over 100, a rare occurrance in this match.

The final position is a theoretical draw, but also came 50 moves after the last pawn move or capture, such that Carlsen could have simply claimed a draw and been leading the match 10 : 6 heading into the blitz. Then, he would have needed just 2½ in the eight game blitz match to ensure overall victory. Instead his margin remains at two points, which gives Nakamura real chances to catch up in the blitz.

Games 7 and 8

Position 558 in Chess960 — Play through the moves on the live diagram!

1.f4 f6 2.e4 e5

Both players have abandoned any kind of hypermodern approach — when there is no theory, or you don't know the theory, you can't go for the equivalent of a Gruenfeld, there is simply no choice but to play classically as that is the most reliable style. Put pawns in the centre, and pieces behind them.

3.fxe5 fxe5 4.Nbc3 Ne6 5.Nd5 It's not clear to me what White wanted to acheive by this knight leap, except if he wanted c3 and
d4 (and if so, then why his 4th?) (5.Bc4 was a good 'classical' move.)

5...c6 6.N5e3 d6 7.g3 Nd7 The initial position used this time was quite an equal one, and White has played a bit lackadaisically, so maybe Black is more comfortable already. 8.Bh3 O-O-O

 
Nakamura vs Carlsen, game 7
Position after 8.O-O-O

9.d3 Kb8 =/+ 10.Qf2 Ndc5 11.Nc3 Nd4 Thinking of ...d5. 12.Ne2 (12.O-O-O g6 doesn't really help; here Black probably changes tack and plays without ...d5.) 12...Nxe2+ 13.Qxe2 d5 14.exd5 cxd5 15.Ng4 (15. O-O-O could have been a good try with the centre opening up, though Black is better after say Qa4 !? =/+)

15...d4 16.Bg2 Bd6 17.h3 Rc8 18.Bf2 Trying to evacuate the king, which in this case is quite a creative defence! (18.Nf2 was consistent, but too slow: Qb5 with the idea of ...Na4 forces major concessions and Black is close to winning.) 18...h5 19.Nh2 e4! (19... Qb5 20. O-O !! is the point, and while Black's position is still more pleasant he has no real attack as such. 20.O-O

20...e3 21.Be1 Ne6 22.Nf3 g5 With so much of a space advantage, Black finds that his forces re-route themselves easily. 23.c3 Basically obliging Black to at least sacrifice a pawn for his attack. g4 24.Nxd4 24.hxg4? hxg4 25.Nxd4 Qh5 is of course close to mate 24...Nxd4 25.cxd4 gxh3 26.Be4 h4 27.Qxe3 Bh7 27...Bd5 28.Rf3 Qg8 is better implementation, just because d5 is a better square for the bishop. 28.Rf3 28.g4!? Qe6 29.Qxh3 Rcg8-+ doesn't seem like a fully conclusive attack just yet, but Black is of course close to winning. 28...Qh5 29.Bf2 Rhf8 30.Rxf8 Rxf8 31.Bxh7 Qxh7 32.g4 The best practical chance. h2+ 33.Kh1 Qg8 34.Bxh4 34.Re1 Qxg4 35.d5 might oblige Black to do more work, since he doesn't have obvious attacking moves now. 34...Qxg4 35.Bf2 Qg8 36.Bh4 Qd5+ 37.Qe4 Qf7 38.Qg2 Qf4 39.Bg5 Qxd4 Restoring the material parity, not that that has mattered for a while. Eventually, White's chronically insecure g5-bishop and long diagonal will combine in some decisive way. 40.Bh6 Re8 41.Rd1 Qxd3 42.Rf1 Ka8 43.Rc1 Bb8 44.Qd2 Qe4+ 45.Qg2 Qe1+ 46.Qf1 Qe6 White didn't see a point continuing with the dance; at any rate, ...Rg8-g3 will force the White queen off the long diagonal.

Game 8

Nakamura really did need to win this game to keep the excitment factor high in the final day of the match, but nobody would have predicted that he would score the point in the manner that transpired!

1.d4 f5 2.f4 g5!? An interesting 'Benko Gambit'! 3.fxg5 h6 4.Ndc3 4.g6!? It is interesting, perhaps, to see how far we can take the analogy to the Benko. Qxg6 5.h4!? e5! Here Black doesn't need to get involved in the struggle for the squares g5 and g6- a theme which reminds me of the American puzzle game 'connect 4'. Instead, he can hit back in the centre, using the fact that in this Benko, the kings are already more or less safe. 6.Nbc3 6.dxe5?! Nbc6 6...Nbc6 7.d5 4...d5!? An ambitious and maybe not entirely correct move. 4...hxg5 5.e4 f4 gives Black play of full value. 5.g4! The centre is much more important than some flank pawn. 5.gxh6 e5! Here, since e3 is not possible, the White centre instantly loses all its solidity. 5...fxg4 6.e4 White seems to have won the opening battle, but of course the position remains messy and unstereotyped enough that almost anything can happen on short notice. dxe4 7.Nd2 hxg5

8...Nd7 9.Ndxe4 Nf7 10.d5 a6 10...Nfe5 immediately deserved attention. 11.Bd4 Rh6 12.Be2 12.Qg3 Qxc8 13.Be2 Nd6 14.Nxd6 exd6 15.Bxg4 was another way to consolidate the advantage, but probably that chosen in the game was better. 12...Nfe5 13.Nxg5 Rg6 14.Ne6 14.h4 would likely have ended up winning a pawn, since Black cannot really take en passant. White can continue Be3-f4, Qg3, etc, and take on g4 with a position that must be close to winning. 14...Bxe6 14...Nf3?! 15.Bxf3 gxf3 16.Rf1± looks like it makes the position interesting, but in fact the clarification is only to White's advantage. 15.dxe6 Rxe6 Logically, the only way Black can try and hang on is to take a pawn for his troubles. 16.Bxe5 Rxe5 17.Qg3 Bh6+ 18.Kb1 Re3 19.Qxg4

20.Nd5 Re5 21.Bxa6 21.Qg3!? is a hard move to spot. The point is e6 22.Nxc7! Kxc7 23.Rxd7+ and White emerges with an extra pawn. 21...c6 21...bxa6 22.Qc4 Rxd5 23.Qxa6+ Kb8 24.Rxd5 Nb6 25.Rxd8+ Qxd8 is not curtains, but White would likely have enjoyed this a fair bit. 22.Nb6+ Kc7 23.Nxd7 Rxd7 24.Rxd7+ Qxd7 25.Qxd7+ Kxd7 26.Bxb7! Maximalist and... correct. 26.Bd3 is more conservative and White could have tried to press here instead, although in fairness it does seem to me that Black can hold the balance with active play. Kd6 27.a3 Re3 and next there may follow ...e5 and ...Bf4 26...Ra5 27.Re1 27.Rg1! was playable immediately, based on Bxc6-type tactics. Bf4 28.Rg4! 28.Rg6 Bd6 is less clear 28...Bxh2 29.Rc4± White has managed to extricate the bishop. 27...Bg5 28.Rg1 Now White still gains a tempo, but it is the wrong one, and ...Rb5 will gain it back later. Bf6 29.Rg8 Rb5 30.Bc8+ Kc7 31.b3 Re5 32.Kc1 Re2 The idea of ...Bc3 means that White's pieces are still just about tactically unfortunate enough to generate some counterchances for his opponent. 33.h3 33.Bg4 Rxh2 34.a4 is of course a try but not really what White wants to do if there is a choice 33...e6?! 33...Bc3 leads to White holding both pawns, even if the resulting position looks nearly impossible for him to win: 34.Bg4 Re1+ 35.Bd1 Rh1 36.Rg3 Be5 37.Rd3 34.Ba6 34.Kd1! Re3 35.Kd2 Rxh3 36.Bxe6± 34...Re3 35.Kd2 Rxh3 36.Bd3 Rh2+ 37.Ke3 Bc3 38.a4 White has played slightly inaccurately and had to give back one of the pawns, but his king is now out of any danger. Kd6 39.Rg6 Rh3+ 40.Ke4 Rh4+ 41.Kf3 Rh3+ 42.Kg2 Rh7!? Trying to swap rooks, even at the cost of a pawn. 43.Rg4 43.Rxe6+ Kxe6 44.Bxh7 Kd5 45.Kf3 Kd4 46.Be4 c5 47.Bd3 Ba5 48.Kf4 Kd5= is a draw: Black meets Ke2 with ...Kd4 and Ke8 with ...Kd6, then White has no way in. 43...Rg7 44.Bg6 c5 45.Kf3 Ba5 46.Ke2 c4 Reasonable active defence, although it was also possible to sit and ask White what he intends to do about the pin on the g-file. 47.Rd4+ Ke7 48.Be4 cxb3 49.cxb3 Rg3 50.Bf3 Rg1 51.b4 Bc7 52.Rc4 Bd6 53.Be4 53.b5 and I suspect the position is now technically winning. 53...Rg3 54.Kd2 Rb3 55.b5 Be5 56.Bc2 Rb2 57.Rc6 Kd7 58.Ra6 Bd6 59.Kc3 Be5+ 60.Kd3 Bf4 61.a5 Bc7! Avoiding the cheap tactic; now sooner or later White has to consent to the swap of two pawns for a bishop. 62.Ra7 Kd6 63.Ra6+ Kd7 64.b6 Bxb6 65.axb6 Kc6 66.Ba4+ Kb7 67.Ra7+ Kxb6 68.Re7 Kc5 69.Rxe6 Now, White tried for 50 moves to win with rook and bishop against rook, but it didn't exactly work out! Rb4 70.Bc2 Rd4+ 71.Ke3 Rd8 72.Be4 Rd6 73.Re5+ Kb6 74.Bd5 Kc5 75.Ke4 Rd8 76.Bf7+ Kc6 77.Rh5 Rd1 78.Bb3 Rd2 79.Bd5+ Kc5 80.Bf7+ Kc6 81.Bb3 Kd6 82.Ke3 Rb2 83.Bc4 Rg2 84.Bd3 Rg1 85.Kd4 Rd1 86.Rh6+ Ke7 87.Ra6 Kd7 88.Ke4 Ke7 89.Bc4 Rd6 90.Ra7+ Rd7 91.Ra5 Rd1 92.Ke5 Re1+ 93.Kd4 Rd1+ 94.Bd3 Kd6 95.Ra6+ Ke7 96.Ke4 Rd2 97.Ke3 Rd1 98.Ke4 Rd2 99.Bc4 Rd6 100.Ra5 Rd1 101.Ke5 Re1+ 102.Kd5 Rd1+ 103.Kc5 Kf6 104.Ra6+ Kf5 105.Re6 Rc1 106.Re2 Rd1 107.Bb3 Rd8 108.Bc2+ Kf4 109.Re4+ Kf3 110.Rc4 Rf8 111.Kb4 Ke2 112.Kc3 Ke3 113.Re4+ Kf3 114.Rd4 Rc8+ 115.Rc4 Re8 116.Rb4 Re3+ 117.Kb2 Re2 118.Rb3+ Kf2 119.Rc3 Re7

Carlsen flags

GM Jonathan Tisdall, writing on the official site called it "a miracle":

"Watching this, my only thought was that I had witnessed the flip side of the secret of Carlsen’s success — a will to win so extreme that it just could not be physically disarmed...To me it looked like a man in the grip of his basic urge."
