Tim Delaney: This game was played in the final round of a six round Swiss. I had (for me) a good record, and Tibor had (for him) a poor record. Tibor was a much better player than I was, so I had nothing to lose.I played 7...e5 with the idea of exploiting the weakness created at c3. This might not be completely sound, as it results in an isolani at d5, but it gives black active play.
In my opinion, white exchanging twice on d5 right away is dubious as it opens the c file, which black can exploit more readily than white.
With 12...Rc8 black seizes the initiative.
I think 15 Bd2 had to be tried. 15 Kf1 simply concedes to black very much the better game.
16...Rc2 paralyzes white. From here on, white is fighting for a draw.
After 26...Ke5 white is in zugzwang, and must surrender material. the rest is fairly simple.
Tibor Weinberger is perhaps the most sportsmanlike player I have ever met. He stayed for a while to explain the game to kibitzers, even though this was the last round of the tournament. Even going into this game, I was an admirer of his, having seen his demeanor in several other tournaments.
