Still theory but rare. Black avoids any possible weakening of the
queen side with the more ambitious 11...b5 [11...b5 12.Ng5 Bb7 Was
if you
will forgive the pun - wants to play Nxh7 13.Nxh7 Bxg2 14.Nxf6+ Qxf6
15.Kxg2 Ne5 16.Qe4 Nc4 When Black has some compensation; 11...b5
12.Ng5 Ne5 Looks better 13.Qc2 Bb7 and Black is comfortably placed;
11...b5 12.Ne4 looks more natural 12...Nxe4 13.Qxe4 with similar play to
the game] 12.Ne4 [12.Ng5 Ne5 13.Qb1 Bb7 14.Nce4 Nxe4 15.Bxe4 Ng6
16.Bxb7 Qxb7 17.Qe4 Yielded White less than nothing in Szekely - Salov
Kotov Mem Leningrad1984] 12...Nxe4 13.Qxe4 Nf6!
14.Qh4 When you face a machine that sees nine moves ahead its best to
keep it simple [14.Qxa8 wins two rooks for a queen but Black gets lots of
activity for example 14...Bb7 15.Qxf8+ Kxf8 and the natural 16.Bf4 runs
into a) 16.Bd2 e5 17.Bc3 (17.Rad1 e4 18.Ne1 e3) 17...Ne4 18.Rac1 Nxc3
19.Rxc3 e4; b) 16.a3!? e5 17.b4 Bd4 18.Ra2 Ne4; 16...e5! 17.Nxe5 (After
17.Bxe5 Bxf3 18.Bxf6 Qxe2 19.Bxf3 Qxf3 20.Bc3 h5 Threatening g5 and
h4-h3 and if 21.h4 Qxg3+) 17...Bxg2 18.Kxg2 g5 wins a piece] 14...Bb7

19.Qh5 g6 20.Qh4 Qd4 21.Qxd4 Bxd4 22.Kxg2 Bxb2 23.Rab1 Rd2 Black is
better. White naturally prefers the endgame] 17...gxf6 18.Rfd1 Kf8
19.Ne1! Black must be deprived of the bishop pair 19...Bxg2 20.Kxg
20...f5! Fitting in with a dark squared bishop. At some point White might
consider g3-g4 fixing f6 21.Rxd8+ Rxd8 22.Nd3 Bd4 with the idea of
e5-e4 or Rc8-c2 23.Rc1 e5 24.Rc2 [24.e3? Bxe3 25.fxe3 Rxd3] 24...Rd5
25.Nb4 Rb5 26.Nxa6 The position becomes further simplified. White
has a faint hope that he can exploit the weakened kingside pawns but they
are easily defended 26...Rxb2 [26...Bxb2 27.Nc7 Rc5 28.Rxc5 bxc5 Would
give White some chances because of the a pawn; Also 26...Bxb2 27.Nc7
Rc5 28.Rxb2 Rxc7 29.Rxb6 Rc2 30.e3 Rxa2 31.Rf6 would be perfect for
white a pawn up in a rook and pawn ending] 27.Rxb2 Bxb2 28.Nb 4
Kg7 [28...Ke8 29.Nd5+/= x h7] 29.Nd5 Bd4 30.a4 Bc5 31.h3 black cannot really improve its position white may want to play g4 at
some point but this is something of a waiting move to see if black will
play some injudicious moves 31...f6 I think most players would consider
Kg6 32.f3 If allowed white would like to play e4 and g4 and fix the
black pawns but black sees this coming 32...Kg6 [for example
32...Kf7 33.e4 fxe4 34.fxe4 Ke6? 35.g4! followed by a king march to the
queenside would give white good chances to win] 33.e4 [33.Kf1!?]
33...h5 [33...fxe4 34.fxe4 f5 35.Kf3 Should also lead to a draw] 34.g4
[The king march to the queenside is comfortably met by 34.Kf1 fxe4
35.fxe4 f5 36.exf5+ Kxf5] 34...hxg4 35.hxg4 fxe4 36.fxe4 Kg5 37.Kf3
Kg6 white has been in control throughout but never threatened to win
although I would wager even a strong human player would have to sweat
as Black here. 38.Ke2 Kg5 39.Kd3 [39.Kf3 Kg6=] 39...Bg1 40.Kc4 Bf2!
Accurate play is still required [40...Kxg4? 41.Nxf6+ Kf4 42.Kd5 Bf2 43.Nd7
