As a pub-based chess club, they bill themselves as “London’s most exciting and friendly…chess club.” Home matches are played from 6.45pm or 7pm on Mondays and Wednesdays upstairs at The Exmouth Arms pub (Starcross Street, NW1). Catering to all levels, the games are in the upstairs room of the pub which does have sufficient peace and quiet, however if you don’t like a pub atmosphere then this probably isn’t the club for you.
