It's the "split-personality problem". It's title is: "Help me with this self, mate."
What about: 1.Nb1+; Kb2 2. Qd4#
No, that doesn't create the SelfMate and ..Kb2 is illegal . Anyway, I figured it out but it goes against my definition of SelfMate where there is only 1 way to mate yourself. The answer is: 1. Bd1; b3 2. Qd4; b2#.
I don't like this answer because black could also have played 1. ..b4xc3
Solution: 1. Bc2-d1! waiting 1. ... b4xc3 2. Qb6-b2 ... c3xb2# 1. ... b4-b3 2. Qb6-d4 ... b3-b2#
Isn't problem software wonderful : )
I didn't know what self mate meant. Thanks rooperi
There seems to be some confusion.
A selfmate is a special type of problem where white has to force Black to mate White in the stipulated number of moves.
In other words, White is trying to mate himself.
Thanks rooperi, I did not see your first iteration so I didn't consider it a pure selfmate (but now I do!).
