Incorrect puzzle

@Qveen_Sacrifice Well, moving the king just leads to Qxh7# immediately, and there's only one other legal move... So it's definitely not the king move.

@alt-nemo :-)
@TPP-Social, Stockfish says it's game over: white king can't take the bishop and can't move at all, so it's checkmate! Stockfish went crazy!

@Gogland The pawn can take. If we're talking about the same puzzle, you need your Stockfish checked. ;)

@TPP-Social, I am about this joke: lichess.org/analysis/8/8/7k/8/8/8/1pK5/8_b_-_-_0_1#1 Works with a bishop.

@Gogland Just says game over by insufficient material here on Lichess for me, and running locally, SF 11, just says Kxb1 with a dead even eval, then when I capture, it declares the insufficient material. I mean, it's obviously not checkmate. Just a check, where the king could capture or run around the board because a checkmate with a lone bishop and king against a king isn't going to happen. Kings move and capture one square in any of the 8 directions. That bishop is one square away and there are no other impeding pieces. I'm not sure what's wrong with your browser.

@Gogland + means check # means checkmate. It says game over because checkmate can't be delivered due to insufficient material. That's what you're seeing. It's a draw. Lichess just ends the game due to insufficient material before the capture because it doesn't matter.

@TPP-Social
OK Finally I've understood. Stockfish just doesn't allow to play further with insufficient material. :-)

My mistake on that previous puzzle but it's still weird.

Shouldn't try solving when I'm tired, lol
