This is my worst tournament in years. I lost ALL my games. My last two games were lost to Class C players. I had never lost to a class C player before. Now I lost to two of them. The last game was lost just due to sheer carelessness.
Why do I post such terrible games? To remind myself to pay more attention the next time.
The only somewhat good game was against Annie Wang, who tied for the US Woman's Championship. If I had played O-O instead of O-O-O I would have had a good game.
