Obviously there is no reason White should give up a pawn and ruin his position
in three moves!Probably it has something to do with time situation. It happens
sometimes especially when you are not satisfied with thw course of the game
and you don't know exactly what you are doing on the board!} Nxc3 29. Rc2 Ne4
