Not Without a Fight!
I recently lost my 1000th bullet game but NOT without a fight!
In the game below, after checking the opponent's king on the 27th move, I realized a few moments later that the game had suddenly stopped... Whether this realization was made in 2 or 3 seconds or in milliseconds I do not recall. What I failed to realize at the time was that my last move was actually checkmate...
Whatever the reason, a poor physical condition, a distraction or a concentration problem, 2 or 3 seconds in a bullet game can make a big difference. Good thing this fight ended in less than 30 moves!
