I've seen a few stories in threads from players who've had some strange experiences OTB (feel free to share some more here if you have some), and I had one last Sunday which I'd like to share.
It was the last round of the Bristol League Congress; a 5 round event over the course of a weekend, and all in all it was a very fun event. Some of the strong players were kind enough to give me some pearls of wisdom, and generally the feel of the occasion was quite amicable. In attendance was James Sherwin (of Fischer's 1st memorable game).
Anyway, back to my last game. I was on 2.5 pts (in the under 125 BCF) with 1 win and 3 draws and was quite of title contention and as an ungraded not in the running for any grading prize, much like my opponent. Earlier in the tournament this guy flew into a rage at the end of a game claiming his opponent had put him off during the game, but that's a whole different story.
I was white and attacked aggressively in a 6. Bg5 e6 7. f4 line in the Najdorf and in no time at all we found ourselves in an opposite bishops ending. Seeing this, I tentatively asked, "Would you care for a draw?" and calmly waited for a reply. My opponent, seeing that I was looking at him, snapped "I'm thinking!". Fair enough. He declined the offer and presumably wanted to check that I knew how not to lose it (I'd rather be in his position too). 30 moves later we arrived at this position.
Having read opinions on this in the forums before, I was somewhat hesitant about offering a draw again, but since the position had calmed to shuffling and many moves had passed, I asked, "Are you sure about that draw?". His reply was "F*** off! Stop getting so uptight!". People looked round. The arbiter came over and asked him to calm down. More moves were played; his king stayed near my bishop and I shuffled my king, his king came over to mine and I shuffled my bishop. People in the open came for a chuckle at the fiasco that was carrying on.
My flag looked like it was nearly falling, but I had an extra hour after that which the arbiter kindly pointed out after he threatened to play to time me out. (I asked if I could claim a draw there, but I was told I could only do that when I really did only have 2 minutes left). I played a move, maybe a king move or a bishop move, I forget and pressed my clock. He got a book out! Then he went for a little wander! Around move 80 he did finally agree to a draw, but refused the handshake and with another kindly f-word went on his merry way.
Anyway, if you read all that, thanks for letting me vent!
