Surrey v Sussex (Correspondence)
[Best Game (Frank Parr Prize): Daniel Young]

Chess engines aren't omniscient! Slow-burning attacks still give them problems, and in this game they think Black is getting away with some appalling risks until it's far too late. 1.e4 e5 2.Nf3 Nc6 3.Bb5 a6 4.Ba4 Nf6 5.0-0 Be7 6.Re1 b5 7.Bb3 d6 8.c3 0-0 9.h3 Bb7 In the Zaitsev Black often gives up his pawn centre for piece play against e4, so the game can become very sharp. That suited both sides... 10.d4 Re8 11.Nbd2 Bf8 12.a4 This extremely complicated line, a staple of the Kasparov-Karpov matches, is only really suitable for correspondence. Black trades in his centre for a mobile queenside majority, so White must use his extra space to launch a kingside attack. This attack is a slow-burner, making it hard to understand this position even with an engine. 12...h6 13.Bc2 exd4 14.cxd4 Nb4 15.Bb1 c5 16.d5 Nd7 17.Ra3 f5!? Shooting for the moon: Black destabilises the centre, and White has to offer a pawn to keep up the pressure. But this weakens his own king and gives White's pieces access to e4. The older 17... c4 seems more consistent to me, and has a better theoretical reputation. 18.Nh2 Kh8 19.g4 ...h6 makes it easy to open lines, but Black now also has to hand over the e4 and g4 squares. [19.Rg3 is popular, but I didn't like 19...bxa4 20.exf5 Rxe1+ 21.Qxe1 Bxd5 22.Ng4 Nf6 and Black's kingside remains intact. White needs to include his g-pawn in the attack too!] 19...fxe4 20.Nxe4 Bxd5 [=20...Nxd5 21.g5 Re6 22.Rd3!? is awkward - Black dare not divert more kingside defenders, but the tricky 22...N5f6 (22...Nf4 23.Bxf4 Rxe4 24.Rxe4 Bxe4 25.gxh6 gxh6 26.Ng4! Bxd3 27.Qxd3+/- gives White an overwhelming attack for the exchange) 23.gxf6 Bxe4 24.Rde3 d5 25.f3 wins material; 25...Qxf6 26.fxe4 d4 27.e5! Nxe5 28.Re4+/= favours the piece in the middlegame.] 21.g5 bxa4 22.Rg3 White doesn't care about queenside pawns at all - his attack is all that matters. [22.gxh6? also helps Black, believe it or not, since he reaches f6, for example 22...gxh6 23.Bd2 Bb3 24.Bc3+ Bg7 25.Bxg7+ Kxg7 26.Qxd6 Nf6 27.Qg3+ Kh8 28.Qf4 Ra7 29.Nf3 Rg7+ 30.Kh2 Nbd5-/+ and White has lost the initiative.] 22...Bb3 23.Qh5 So Black has two pawns - but all of White's pieces are pointed at his king. He can only survive the next few moves by artificial means: 23...Re6 24.gxh6 g6 , driving White back (25. Rxg6? Qe8). 25.Qg4 Ne5 26.Qe2 Nbc6 27.Qf1 Nd4? A fatal loss of time, after which White's pieces soon flood in. [>=27...Qe7 Incredibly, it looks like Black can survive with perfect play - but who knows? I looked at 28.Bg5 Qf7 29.Bd2 Be7 30.f4 d5 31.Ng5 Bxg5 32.Rxg5 and was sure that Black's position is about to collapse, but was soon disappointed. 32...Nc4 33.Rxe6 Qxe6 34.Rxg6 Rg8 35.f5 Nxd2 36.Qf2 Qf6! Sneaky! When White regains his piece, 37.Qxd2 Ne5 forces simplification. 38.Rxg8+ Kxg8= The computer suggests perpetuals everywhere... which as often as not means it doesn't have a clue what's going on either.] 28.Ng5 Re7 [28...Re8 29.Rxb3! axb3 30.Rxe5 wins everything, whilst; 28...Rf6 29.f4 Nf7 30.Ng4 traps the rook.] 29.f4 It turns out that all this is recommended for Black in Solozhenkin's recent book, "The Spanish Main Road", optimistically evaluated as unclear. I'm sure no human would go near this with a bargepole - such are the perils of trusting published analysis! 29...Nec6 30.Bxg6 Bxh6 31.Rg4! Engines miss this evil little move at low depth, but once the big guns reach h4 White will have too many attackers. 31...Raa7 32.Be3 Kg8 [32...Bc2 loses prettily to 33.Bxd4+ Nxd4 34.Bxc2 Nxc2 35.Rxe7 Qxe7 36.Rh4 Kg7 37.Rxh6! Kxh6 38.Ng4+ Kh5 (Otherwise 39. Qd3(+) is crushing) 39.Ne4 Ne3 40.Ng3+ Kg6 41.Qd3+ Kg7 42.Nxe3 Qe6 43.Ngf5+ Kf8 44.Qxd6+ Qxd6 45.Nxd6+- , and the passed pawns promise White an easy win.] 33.Qf2 Qa5 Only a computer could suggest such a move. Sadly he never removed my b-pawn - then I would be 'all-in' on the kingside with every piece in play! 34.Ne4 Bg7 35.f5 Ne5 36.Bd2 36. f6? Qxe1+! 37. Qxe1 Nf3+ was Black's only idea. The rest is a rout. 36...Qd8 37.f6 Re6 38.Rf1 Nxg6?! Everything loses: [38...Nxg4 39.Nxg4 Bf8 40.Qh4+- threatening 41. f7+ and death; 38...Ndf3+ 39.Nxf3 Nxg4 , the computer effort, is smashed by 40.Bh7+ Kxh7 41.Qh4+ Kg8 42.f7++- bagging the queen; 38...Rxf6 39.Nxf6+ Bxf6 40.Qxf6 Qxf6 41.Rxf6 Nxg4 42.Nxg4+- wins a piece, with Black's pawns dropping soon.] 39.Rxg6 Rxe4 40.Qg2 (Even stronger than 40. Rxg7+) 40...Ree7 41.fxe7 Qxe7 42.Ng4 Kh8 43.Nf6 , and Black resigned, since there is nothing to stop White's heavy pieces flooding in. [43.Nf6 Qe6 44.Bh6 soon breaks in, say after 44...Ne2+ 45.Kh1 Bxf6 46.Rfxf6 Qd5 - White gets his revenge with 47.Bg7+ Rxg7 48.Rf8+ Qg8 49.Rh6+ Rh7 50.Qg6!+- , a curious echo of Black's exploits in the 27... Qe7 variation.] 1-0
