Black needed to try Kc8} 48.Qc6+ Ke7 49.Bg5+ Kf8 {JW: White has a mate in 4 starting with Qc8+ or Qa8+} 50.Qd6+ {JW: This is mate in 5} Kg8 51.Qd8+ Kg7 52.Qf6+ {JW: Correct was 52.Bf6+ which is mate in 3} Kg8 53.Bh6 {JW: Correct idea but overlooking blacks defense. White still could have mated by going back to 53.Qd8+} Qf5+ 54.Qxf5 gxf5 55.Bc1 c4 56.Bb2 Kf8 57.Kg2 {K} Ke7 58.Kf3 Ke6 59.Ke3 {JW: 59.Kf4 would put black in zugzwang 59.Kf4 h6 (h5 60.h3) 60.h5 so instead black needs to move the king right away 59.Kf4 Kd5 60.Kxf5 Kc5 61.Ke4 Kb4 62.Kd4 and wins.} Kd5 60.Kd2 {JW: White can win numerous ways by maintaining control of the e4 sqaure for example 60.f3 Kc5 61.Bc3! the key point in all lines is that white wins by keeping black out of e4 and black will eventually be in zugzwang} Ke4 61.f4 Kf3 62.Kc3 {JW: Blacks pawns aren't going anywhere. white should just continue making moves with his bishop until black runs out of useful moves. blacks only try would be to run the h pawn down the board but this will eventually allow white a passed h pawn and comfortable win.} Kg2 63.Kxc4 Kxh2 64.Kd5 Kxg3 65.Kd6 h5 66.Ke7 Kxf4 67.Kxf7 h4 68.e6 h3 69.e7 h2 70.e8=Q h1=Q 71.Qe5+ Kg4 72.Qg7+ Kf4 73.Qe5+ Kg4 74.Qg7+ {JW: An interesting game throughout} {#d}
