Weird checkmate contest
Happened once in a bullet game. I was black with 3 seconds left and I was playing only to prolong the game by capturing pieces before flagging. I would probably have lost in 7 more moves since I was not using premoves at all. Never did I expect the knight fork to be checkmate (I had intended to capture the other bishop).
