A very strange game.


I've calculated that type of thing before. The idea of having 4 queens on the board scares me immensely, so I will avoid it.
Nice game. Four queens are always a mess to deal with and you handled the challenge admirably.
That being stated, black missed a win on move 40: ... RC5! exchanging down to a won king and pawn endgame. Instead, said opponent went for the rook check and ended up playing into a drawish, and later, losing game.

wow. crazy game. your opponent did blunder by not taking that h3 pawn and drawing the game. I am going to look at this one some more.
