After 28.Kxg2 Nxe3+ 29.Kf3 Nxd1 30.Bxd1 d4 31.Bd2 Rb8 32.b4 Rb7 33.Ke4 Diagram black has his two pawns for the two minors, but the fact again that these two minors are both bishops makes me wonder. In my endgame studies I have seen that certainly this battle between rook and two bishops requires compensation for the rook side, and by the way at this juncture Fritz finally agrees with me.33...Rd6 34.Bb3 Re7+ 35.Re5! not fearing a fight between merely two bishops and a rook, even down two pawns, this bucket of bolts says! 35...Rxe5+ 36.fxe5 Rd8 a) 36...Rg6 37.Kxd4 Rg2 38.Be3; b) 36...Rd7 37.e6 Re7 38.Bg5 Re8 (b) 38...f6 39.Bf4 Kf8 40.Kxd4) 39.e7 h6 40.Ba4 Rc8 (b) 40...f5+ 41.Kxf5) 41.Bf4 f5+ 42.Kxf5 Kf7; 37.b5 h6 38.h4 Rb8 39.Bc4 Diagram The big issues in this position, I would say, is white's active king and ability to blockade black's passer. For the time being, black's kingside majority is held up. The bishops are extremely deft at controlling squares and make the clumsy ox rook look silly. Fritz scores white up 84 hundredths of a pawn here, believe it or not.] 28...Be4 29.Rxa7 d4 30.exd4 Nxd4 31.Bg4 Rb8 32.Bd7 Bf5 33.Bxd4 Rxd7 34.Rxd7 Bxd7 35.Rxg7+ Kf8 36.Rxh7 Rb4?? 37.Rh8+ Ke7 38.Bc5+ 1-0
