Now that's one chess move I haven't seen before.
Polish National Chess Champion Falls Out Of Chair After Loss

In other sports bloopers, this is a video of Polish National Chess Champion Pawel Teclaf making a game-losing move during the World Blitz Chess Championship and instantly becoming so upset with himself he falls out of his chair. Who knew chess was such an action sport? For reference, I would have flipped the board and tackled my opponent instead, but that’s just me and I’m nothing if not a sore loser.
