Oops, this isn't a win, but it is a time thing I once got down to 1 minute around move 40 and lived off of my 30 second increment till move 110. Although the last 50 moves were me proving I had a fortress... it took some care at that point but wasn't anything too tough. Still, that's a lot of moves for such low time.
My opponent was in a similar situation, around move 40 we were both very low.
... never won a big tournament game with literally 1 second left on the clock. This weekend some of my students and I competed at the Central Florida Class Championships. DC_cookie_G's (his nick here) Saturday morning g/60 Class "D" 1st round match was about as exciting as chess can get... he was almost hyper-ventilating exiting the playing hall and had to walk around the hotel to calm down. What made it laughably worse was that he kept writing down his moves almost to the one second mark!... notation I like to call "panic squiggle".
Both players had Queens and other major pieces left on the board so it wasnt one of those easy King+ Queen vs. lone King type ending, but a real find the forced mate in 3 at the last second kinda mate.
Great job DC!... with that win and a solid tournament (3-2).
Anyone else have a last second tornaament chess win?
