Board 1. G/75+5 (delay). A48 King's Indian Defense vs. London System. 1.d4 Nf6 2.Nf3 g6 3.Bf4 Bg7 4.Nbd2 d6 This is okay but 4...c5! ∆5.e3 cxd4! 5...d6 was played in Alekhine - Euwe : London 1922 6.exd4 d5 , transposing into an Exchange Caro-Kann. 5.e4 Nbd7 This may be inaccurate. 5...0-0 C. Watson - Euwe : London 1922 & 5...Nc6 (Auffenberg - Chirkov : Weymouth, ENG 1968) are good alternatives. 6.Bc4 c6
A rare reply. Castling is usual & the engine recommends 6...c5 Sukandar - Richards : Melbourne 2014. 7.Qe2N Already a new move. Previously seen here were: 7.0-0 0-0 8.Re1 Vink - Kerstens : Hengelo 1997 7.Bb3 Wagle - Kirschner : Schoeneck 2002 & 7.h3 d5 8.Bd3 Qa5 9.c3 dxe4 10.Nxe4 Nxe4 11.Bxe4 Burch - Coburn : England 2010 7...d5 7...0-0 /\ ... Nxe4! & 7...Nh5 8.Be3 e5 were options. 8.Bb3 Now the game takes-on a Gurgenidze CK character. 8.exd5 cxd5 9.Bd3 9.Bb3 a5= 9...Nh5 10.Be3 Qc7 is of little or no improvement. 8...dxe4 9.Nxe4 Nxe4 10.Qxe4 Nf6 11.Qe2
11...0-0?! 11...a5 12.a4 Bg4 13.c3 13.Bxf7+ Kxf7 14.Ne5+ Ke8 15.Nxg4 Nxg4 16.Qxg4 Qxd4= 13...Nd5 14.Bg3 Qb6= 12.0-0 12.h3 preventing the following. 12...Bg4 Black is a tempo down vs. 1.e4 c6 2.d4 d5 3.Nc3 g6 4.Nf3 Bg7 5.Bf4 dxe4 6.Nxe4 Nd7 7.Bc4 Ngf6 8. Nxf6+ Nxf6 9.0–0 0–0 10.Qe2 Bg4 (D. Mann - Athens : correspondence, IECG 1998, with transposition) but White's extra move (Bb3) is of no benefit. 13.Rad1 Nd5 14.Bg5 h6 15.Bc1 ≤15.Bh4 Bf6! 16.Bg3 a5 15...Qc7 16.h3 Bxf3 17.Qxf3 e6 18.Rfe1 Rad8 19.c3 Rd7
20.h4 Qd8 21.h5 g5 22.Bc2 Nf6 23.Re5 Rd5? 23...Re8= 24.Bb3?! 24.Qe2 24...Rd7 25.Qh3 Nd5 26.Re4 Nf6 26...c5! 27.dxc5 Nf4 28.Qf3 Rxd1+ 29.Qxd1 Qxd1+ 30.Bxd1 Nd3 31.Be3 Nxb2 27.Ree1 Qc7 Time check: White has 26 minutes left vs. Black's 18. 28.Bc2 Rfd8 29.Rd3
29...c5 Black finally (some 25 moves late!) gets in his thematic break & eliminates White's space advantage. 30.dxc5 30.Be3?? cxd4 31.Bxd4? loses to Rxd4! 32.Rxd4 Rxd4 33.cxd4 Qxc2 30...Rxd3 31.Bxd3 Qxc5 32.Be2 Qa5 Black offers a draw. 33.a3 White declines but his outside majority & B pair are only illusory advantages. Qa4 34.Qf3 b6 35.Rd1 Rxd1+ 36.Bxd1 Qe4 This forces a Q trade. 37.Qxe4 Nxe4
38.Kf1 Bf8?! 38...f5! 39.Bf3 Nf6 40.Be3 Bd6 41.Bd4 Nd7?! 41...e5= 42.Ke1!? 42.Bc6 e5 43.Bxd7 exd4 44.cxd4 wins a P but creates an opposite Bs ending. 42...Bc5 This forces a trade of Bs. 43.Bxc5 Nxc5 43...bxc5! 44.Kd2 Kf8 45.Bc6
45.b4 Nd7 46.Kd3 Ke7 47.Kc4 but Kd6 48.Kb5 Kc7 49.Ka6 Kb8 gets Black to the Q-side in time. 45...e5? 45...Ke7 46.b4 Kd6 46...Na6!? 47.bxc5+ Kxc6 48.cxb6 axb6= was right. 46.Ke3 46.g4! Ke7 47.b4 Ne6 48.Ke3± would have given White winning chances. 46...f5! 47.Bd5? 47.b4= 47...Ke7? 47...Na4 48.g3?? 48.b4 48...Nd7? 48...Na4-+ 49.Kd3?? 49.Bb3 49...Nf6-+
Black offers a draw. White accepts. Game drawn by agreement. Time left - Kernighan 0:40, Moldovan 6:14. Estimated time used - Kernighan 78: 25, Moldovan 72:46. Longest thinks: White - 9 minutes for 3.Bf4. Black - 7 minutes for 6...c6. ½–½
