I can't see how white can convert this to victory.

Re: #40 according Ottó Bláthy
It is a helpmate and not a direct mate problem.

Re: #40 according Ottó Bláthy
why should white allow being mated when a stalemate is possible?

Re: #40 according Ottó Bláthy.
Hello Andreas:
It is like suicide chess or giveaway or whatever you name it. Why losing when you can win? As I said before: there are different targets. The 'lose is win' concept is not exclusive of chess and can be found in other games such as draughts/checkers (is it a draw in English/American variation?) and Russian draughts (poddavki, which is very popular; as well as the normal 'a win is a win' shashki).
Why do not have these versions? It is a rhetorical question. However, ChestUCI 5.2 found a solution in one second but in 38 moves:
Regards from Spain.

Helpmates are a sort of problems with their own targets. So are selfmates and both of them are supported by ChestUCI mate solver. Currently, Wikipedia talks about colours but either colour is suitable for these kind of problems.styx wrote:Why should white allow being mated when a stalemate is possible?
