Last night at the Spokane Chess Club, we had a game/29 tournament. I like this time control because the USCF rates it only as quick, while game/30 is dual-rated. I was the third seed, and the first round went as expected: my opponent hung his queen early, making the game easier than it should have been. In round two, I played Phil Weyland--the second seed--and blundered into a theoretically lost game. But, as they say, the hardest thing in chess is to win a won game. He got into time trouble looking for the best plan, and I very nearly equalized. He offered a draw when he had one minute to my five and was only one pawn ahead in what looked to soon become a rook and pawn endgame.
In the final round, Phil played the top seed while I had White against Judge Korsmo. My oversight created opportunities for some tactics that Korsmo played in the wrong sequence, missing his chance for an upset win.

I thought about grabbing the pawn, but decided if I could get the queens off the board, the moves required for my opponent to get the bishop back into the game might give me time to create a passed pawn. I was wrong.
Here my opponent offered a draw. Objectively the game is probably drawn despite his one pawn advantage, but I have some forcing moves. He must defend accurately.

29...g5 and Black has the edge
This obvious looking move loses.
I wanted to play 32.h4, but thought the black queen could just snap off the pawn because I overlooked the winning skewer.

Both of us had two minutes left and checkmate is imminent. My opponent let his clock run out looking for the escape that is not there.
