Wow, crazy game! Very well played under the circumstances!

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.

that looked hard. Good job keeping your cool.

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.

Ya, you are right. After the exchanges, my opponent could have got a passed h-pawn.

No, We would still be equal.

 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.

Nice! I never had a game with 4 queens activelly roaming the board.

This game looks very interesting. I have to admit that I also have never had more than the usual 2-3 queens on a board before. Good job keeping your cool.

Wow. A total of 5 different queens.

I think you mean "your opponent did blunder by not taking that h3 rook and drawing the game" on move 52. Yep.
