Qg4# {A very nice game by White although Black missed his one chance to play actively in the centre and show that White's pawn advances did in fact expose the White monarch somewhat. Missing this opportunity to distract the White pieces from the attack allowed White to advance in this game no less than two pawns to the sixth rank. Such a pawn advance produces a critical situation for the opponent as opening lines, and thus breaching the oppoents defences, cannot now be avoided. This seems to be a generally applicable rule that if pawns are able to advance so far without any distraction in the centre of the board then the consequences are usually fatal for the defender.}) 1-0
