Is this ethical ?
Yes, it's ethical. White failed to make sure the king was safe. Why should white win if he's unable to do this?
Perpetual check is accepted as a legit way to draw a game, I think, although it doesn't look like black had one here, so white shouldn't have accepted a draw.
In the position where white accepts a draw, he has no choice but to allow a repetition. Black will play Qd3+ and if Qg3 Qf1+ repeats. If the white king ever goes to h4, black plays g5+ Kh5 g6# checkmate. I think earlier white might have avoided this (8. Qg4 might have been a good choice).
Agree, completely ethical. 1...Bxf2 was an excellent last-ditch attempt at a draw, and White did not play accurately enough to earn the win (eg, 8.Kg2?! and 14.Qg3?).
hmm, I spose Qg4 would've been a lot better. : ) oops.
In any case, I was just wondering if perpetual check was legit or bush league. I guess it's legit. Thanks.
Not only is it ethical, it's a downright nice save after white missed 8. Qg4 (as has been pointed out). Well played by black.
I hate it, especially when someone starts doing it when the game is still fully open with no obvious advantage to either side, but I agree with the others that its a totally legitimate part of the game.
two moves more and black queen lost her ability and white paw would turn to queen, so white lost without necesity
