| Artar1: A fascinating game, but White missed some important opportunities. <1.e4 c5 2.Nf3 d6 3.d4 cxd4 4.Nxd4 Nf6 5.Nc3 a6 6.a4 e5 7.Nf3 Qc7 8.Be3 h6 9.Be2 Be7 10.0–0 Be6 11.a5 Qc6 12.Nd2 Nbd7 13.Bf3 0–0 14.Re1 Rac8 15.Nf1 Rfd8 16.Re2> (Why not Ng3?) <16...Bf8 17.Rd2 Qc7 18.h3 Qb8 19.Na4 Nc5 20.Ng3 Nxa4 21.Rxa4 g6 22.b3 Rc3 23.Ne2 Rxe3>

However, the evaluation is still in White's favor. <24.fxe3 Qa7 25.Kf2> Also worth a try is <25.Rd3> Now if <25...h5 26.Qe1 Rc8 27.Nc3 Bh6 28.Ra2 g5 29.g4 hxg4 30.Bxg4 Qc5 (30...Nxg4 31.hxg4 Bxg4 32.Nd5 Kf8 33.Qf2> Makes Black's position vulnerable to attack.) <31.Nd5 Nxd5 32.exd5 Bxg4 33.hxg4> White's position not only holds but gives the first player a potentially winning endgame.

A passive move that hands the initiative to Black. Better is <34.Bxe4 Rc3 35.Rd3 (35.Bd3 Nf6 36.Re1 Nxd5 37.Qf3 Qc5 38.Re2 Nf4 39.Rd2 Nd5 40.Re2=) 35...Nc5 36.Kf3 Nxd3 37.Bxd3 Qc5 38.e4=>
