Задача 191: Steven Dowd - Selfmate

dowd(17.05.2013) Парадоксална и трудна идея в Обратен мат от Steven Dowd от САЩ!


Set: 1…d4#
Sol: 1.Bh6! (unpin) f5! 2.Qf4+ Kf6 3.Qd6 (pin) d4+ (3…f4+ transposes)

4.Kf3 f4 5.Se4+ Kf5 6.Sg5+ Kf6 7.Bb1 d3 8.Sh7+ Kf5

9.Rg2 e5 (d3 is pinned and e6 no longer) 10.Ref2 e4#

I have been composing FM pawn mates in which the idea is to take a position in which one pawn (of three) mates in the setplay but in the end all three pawns take part in a model mate. These have been very difficult to construct, and take days to proof, often ending up cooked.

I have been working for some weeks on an idea of unpinning a back pawn and then pinning a front pawn to allow for this attractive mate. Here is the only one that ended up sound, with a second pinning as well, giving a pin on all three black pawns throughout the solution. (Author)
