Hi guys, today I blundered my queen but my opponent sidn't see it. He continued with the game... Until today, I resigned immediately when I made a blunder :) But now I know that I must wait. Notice that I was playing bullet and I am 1900.
Garry Kasparov made a similar mistake in Game 2 of his 1997 match against Deep Blue. He resigned right after Deep Blue made a blunder that allowed him a draw by perpetual check. He was so trusting of the machine's ability to calculate that he did not even bother to look for a perpetual check.
