[D]8/6pp/3k4/3P1PP1/p2K4/8/8/8 b - - 0 51 This is from my correspondence game. I am going to play 51...a3 mate in 24 and if 52.Kc3 then Kxd5 and if 53.g6 hxg6 and if 54.fxg6 Ke4 and if 55.Kb3 Kxf5 and if 56.Kxa3 Kxg6 I think that this time I can say mate in at most 18 in my next move even if my opponent declines the condition and the only thing that I need to be careful is not to do a mistake in writing the moves and not to be dead. I need to use full notation in numbers and it means 51...a4a3(1413) 52.Kd4c3(4433) Kd6xd5(4645) 53.g5g6(7576) h7xg6(8776) 54.f5xg6(6576) Kd5e4(4554) 55.Kc3b3(3323) Ke4f5(5465) 56.Kb3xa3(2313) Kf5xg6(6576) I already posted the previous position 1-2 weeks ago but nobody responded about the mate so I post it again [D]8/4k1pp/8/3P1PP1/p1K5/8/8/8 b - - 0 50 I played 50..Kd6 mate in 26 with the condition 51.g6 hxg6 52.fxg6 a3 53.Kb3 Kxd5 54.Kxa3 Ke4 My opponent replied 51.Kd4 The interesting question is how many cards I need to win the game(I do not expect my opponent to resign). I can post only a condition of one line and if I send my opponent a tree of more than 1 line then he has the right to ignore it in his reply. Here is part of the analysis of yace under chessbase of the position after 51...a4a3(my last move that I am going to send to my opponent tomorrow) and of the positions after it when my opponent avoid 52.Kc3 (I deleted lines at small depth except lines with mate score and it happened when yace showed a mate score in the root only to forget about it later) 8/6pp/3k4/3P1PP1/3K4/p7/8/8 w -
