Chess Suicide
Sort:
Clever.
Wait, I still don't get the purpose of the rook's moves. Can anyone explain?

I can explain.
If the Bishops are face-to-face (zero squares seperating them) then the Rook cannot be on c8, d8, e8, f8 or g8; because Black can then (after creeping the face-to-face Bishops back to b7 and c6) play BxB, forcing the Rook to recapture (or block) and spoiling the mate.
If the Bishops have one square seperating them, the Rook cannot be on d8, e8, f8 or g8; for the same reason.
If the Bishops have two squares seperating them, the Rook cannot be on e8, f8 or g8; for the same reason.
... and so on.
So: since White cannot "pass" (ie: he must make a move each time it's his turn) you can make up a table of which square the Rook MUST be on if the Bishops are seperated by a certain number of squares:
zero squares: h8
one square: c8
two squares: d8
three squares: e8
four squares: f8
Example: Why can't White start by playing Rh8 on move 1? Because that's the square that he needs to play the Rook TO if Black moves his Bishop to a square that leaves zero squares between the Bishops.
So if White started with 1. Rh8, Black would reply 1. ... Bf3! and now White is SUPPOSED to play Rh8, but he can't because his Rook is ALREADY on that square!
Ah, I see. That's an impressive composition, and we here don't see selfmates often. Is that yours?

This was fun to play through and see there were just no choices left.
Still a cool puzzle. First suicide puzzle I've ever seen. Would love to see more!
...
usually i come to forums to make fun. alas, this one deserves credit. nice work.
That is what real suicide looks like!
Oh the horror!
No, I think my discription is more accurate

Try searching for selfmate problems. I see a good stash of them here, and googling should yield even more results.

Some selfmate problems are cooperative though... both sides cooperating to set up the mate. In this one, the roles are reversed: one side trying to GET mated, and the other side trying to avoid doing it.
No matter, i liked also
Those that are cooperative are called helpmates, not selfmates.
White to play and FORCE Black to mate him. Black will try to avoid delivering mate.
