Does that lose the queen to g5+, or am I looking at this too fast?

Originally posted by Paul Dirac II57.c8=Q was the final mistake for White. He should have first played 57.Qf7+ and then 58.c8=Q because the stalemate is eliminated. No, there would be a mate for Black then because he can play 57...Kh6, so to also eliminate the mate, White would have to move 58.Qf8+ to drive the black King back to h7, then White could promote the pawn with advantage.
May I violate the letter of the law of this thread by putting up a game that I was not involved in? I have been randomly selecting public games by others to look at. The ending of Game 9573569 is spiffy. Black’s king move at 55 is evidence he already had up his sleeve a way to avoid the loss even though he is down by a bishop and three pawns. At 7 56. c7 Qe4xe3 57. c8=Q g5 58. Qf6xg5 Qe3xh3 59. Kh4xh3 1/2-1/2[/pgn]
White has a winning advantage.

[pg xt move} 2. Qf8+ Kh7 3. c8=Q g5+ 4. Kh5 Qxh3+ 5. Kxg5 [/pgn]

57. Qf7+ Kh6 (not Kh8 because of 58.c8=Q+ and mate next move) 58. Qf8+ Kh7 59. c8=Q g5+ 60. Kh5 Qxh3+ 61. Kxg5
White has a winning advantage

Originally posted by chessicleHow badly did it hurt to give up your advanced passed pawn at 63? Were you able to see at that point how to get the win?

Fun Finish:
When I learned to play chess (ie learned to play (to the extent that I can) rather than learned the rules of the game) twenty years or so ago, it was in a chess club where the game was a social thing. There were lots of us playing five minute chess and chatting as we did so, and competitive chess was very much not the focus for us. This has carried on into my play on here, because I tend to make my moves very quickly, and only occasionally pause and make any sort of analysis of a position - so my games on here are, largely, played to the time (on my side) of a five minute game. And in that situation, seeing the stalemate trap and avoiding it, with an easy win, is enough, and so I didn't look for the fun. Maybe I need to slow down, play fewer games, and aim to play to a higher standard.
Originally posted by Paul Dirac IIThere was no way to improve the position on the Queen-side and promote that pawn, so all I could do was use it to hold up Black while I optimized my pieces, then sacrifice it to get everything I could on the King-side. I thought it would be enough (I could see I would have K+N+4P vs K+R+P), but I certainly didn't calculate it all the way to a win.

Gratified by the response to my last game on here, I thought I'd post an interesting pair of games. The Exchange Variations of the French and Slav Defences don't give pawn structures which generally lead to interesting games (major piece exchanges down the e-file or c-file make for a lot of simplification), but that's what I played in these two games, and I think both games were quite interesting. They make a nice pair, not only because of the openings, but because of the endings, which have exactly the same material, including pawns on the same files at the very end.
I am sure there are lots of mistakes in the middle-games to be found.

Hope you enjoy!
Another game I was NOT involved in is the longest game I have seen at this site.
Game 9490830
At 72 it becomes knight + bishop vs. nothing. Does theory say a win can be forced? Or does it take a mistake? Checkmate is achieved at 168. I would love to know if white was offering a draw during the second half of the game.
Originally posted by Paul Dirac IIYes, it is a forced win, although you have to make sure you do it in under 50 moves. I dont know why white didn't claim a draw?
