Pawn and Two: At move 37, Fritz preferred (-.06) (20 ply) 37.Rb1 Bd4 38.Kh2 Bf7 39.Rfd1, with an approximately equal position.After 37.h5 Bxe1, Stahlberg's 38.hxg6, was a better choice than 38.Rxe1, although the later move also gave drawing chances: 38.Rxe1 Bf7 39.h6+ Kxh6 40.f3 Qe7 41.fxe4 Re8, (-.69) (22 ply) 42.Kf2 fxe4 43.Bxe4 Bg6, (-.79) (21 ply) 44.Rh1+ Kg7 45.Qb2+ Qf6+ 46.Qxf6+ Kxf6 47.Bxg6 Kxg6 48.Rd1, or 47...hxg6 48.Kf3.
After 38.hxg6 Bc3 39.gxh7 Rh8, Bronstein, in the tournament book, states that white should next play 40.Kg2 and 41.Rh1, and then he indicates, the draw would have been quite obvious.
After 40.Kg2 Rxh7 41.Rh1 Rxh1 42.Kxh1 Qe8 43.Kg2 Qg6 44.Bd1, (-.58) (21 ply) 44...b5 45.Qh5 Qxh5 46.Bxh5 bxc4 47.bxc4, and the result should be a draw.
After Stahlberg played 40.Qe3?, Kotov obtained strong winning chances with 40...Kg6!.
Bronstein pointed out that 40...Kg6! fulfills three tasks with one move: defending g5, clearing the queen's path to h7, and avoiding the check. Bronstein stated that suddenly, and unexpectedly, the white king is in trouble.
sac: 37...Bxe1
