After my first one was solved so quickly, it's time for the next meal! It's another one that I created for the same mentioned site. Warning: this is a fairly long one, even with its simple strategy!

White Selfmates In How Many Moves?

enter image description here


1 Answer 1


Thanks to @retudin for pointing in comments to the subtelty I was missing before

White selfmates in

24 moves.

The plan is pretty straightforward :

White plays only the king while Black marks time with Kd5-d6-d5, captures Pc3, captures Pg5, go to e4, restricts the bK by playing c4, force Black by zugzwang to play ...g5 and ...Bg6#.


1.Kh2 Kd5 ... 9.Kb3 Kd5 10.Kxc3 Kd6 ... 20.Kh6 Kd6 21.Kxg5 Kd5 22.c4! Kd6 23.Kf4 g5 24.Ke4 Bg6#

This nice problem is crystal-clear, with no dual and no way to change to move order.
