Finally a reason to speak:) Yes, I too am an avid chess player and find weed aids my focus a lot. I'm by far a master, but weed helps me build a greater general sense of game as a kind of mental landscape. It's interesting. Coding too is a lot easier to get into and it helps me be more creative with the solutions I choose,more experimental.

I've heard about that weed book before - do you actually own a copy yourself? Any good? Or the other book on that link you gave, about meditation and creativity?
