A Nervous Opponent

Hi!

This is my 2nd game in the Icelandic Chess Club Champioships a few weeks ago. My opponent sat at the board, and he had an almost angry look on his face, which I could not read quite well- did not know what it meant. Again, I had White, but was going on 3 1/2 hours of sleep, so I was wondering how I would play chess, 2 rounds that day, about 4 hours each, with so little sleep! After a few moves I realized my opponent was very nervous; so nervous, it seemed to me his nerves did not allow him to see the board clearly.
