Reza is a fine young man who was undefeated when he played me a checker game. Mid way through he inquired if I was using a program (very politely) and I assured him I was not. I was flattered he thought I was playing on that level. My very un-machine like ending where I turned sure victory into a draw convinced him. LOL. He is a very bright and promising young guy and I have nothing but good things to say about him. (not that he needs MY endorsement) LOL
