1.d4 Nf6 2.Nf3 e6 3.e3 b6 4.Bd3 Bb7 5.0-0 The prescribed response to a Queen's Indian set-up is for White to play Ne5 and follow it with f4. 5...c5 6.Nbd2 d5 7.c3 Bd6 8.Qe2 Ne4 To prevent e4. 9.Bb5+=/+ Nd7 10.Nxe4 dxe4 White thought this might have been a weak pawn, but past experience of similar positions has shown that it would be an asset for Black. 11.Nd2 Qc7= 12.g3?!=/+ [ 12.f4 Best (Hiarcs 9). 12...exf3 13.Nxf3 Be4 14.Bd2 0-0 15.Ng5 Bg6= ]

Again, White must take his chances in an inferior endgame that Black would probably find very difficult to win. 27...Qxc5 28.dxc5 g5 29.Kg2 Bd5 30.Rd4 b3 31.Rb4 Ra5 32.Na4 Bc6 33.Nc3 Rxc5 34.Rxb3 h5-+ ] Top 27...h6 28.Qf1 Bd5 29.Rc5 b3 30.Qc1?
