Greetings from Minneapolis, USA! I am an OTB player as well. I am using this site for my training games. If you are an OTB player, I am curious to get to know you by name, and I hope we meet someday. I am a personal trainer to kirbythecat. My friend calls me tournament Punching Bag, PB for short.
As this is my training ground for OTB chess, I avoid using reference material of any kind while my game is in progress, but hopefully, after the game, I do my analysis, but even this seems to be a rarity. Enjoy and good luck!
