Pre-register for upcoming club tournaments, lectures, and other events of the Columbia Chess Club (on-site registration accepted too).
Casual Play starts every Thursday at 5 p.m. and runs until closing, with rated tournaments running alongside casual play starting at 6 p.m.
How to interpret time controls: Times such as "G/65;d5" can be read as "Each player gets 65 minutes to complete the game, with 5 seconds of delay each move."
