Let me share this nice memory with you, way back on the 4.11.2011:
A win with Black would have enabled me to jump over the magical border of 2200 FIDE-Elo, draw wouldn't have been sufficient.
So at first everything went smoothly, I had a good position and the better time. The opponent felt compelled to sacrifice which was unsound, too. Well then!
Unfortunately I messed up everything in the time-scramble before move 40 and emerged with an probably equal game, 3 connected pawns for a bishop. So what to do? I couldn't bring me to accepting the draw offer and made some moves mechanically.
If white hadn't pushed his pawns probably draw would have been the most natural result. After 62. ... Bf1!! my mood was rising steeply - the position became difficult out of a sudden.
