OKbridge is a large international 24/7 online bridge club, accessible through the OKbridge website. OKbridge is not free, but members get a high standard of ethics and play (through multiple daily 12 board barometer style tournaments and table hosted standalone boards) in return. OKbridge's Lehman rating system supports finding suitable partners.
I was an OKbridge member since 2001-01-01 (until end 2012).
My OKbridge stats could be viewed through my public OKbridge profile (requiring login, for player name 'ericbaes'). I only played IMP boards/tourneys (disregarding my 50.00 MP Lehman rating).
By the way, this is what I looked like on OKbridge:
Back in 2002, I wrote software to automate the doubledummy analysis of all boards that I would ever play on OKbridge, resulting in the following generated website. This website got updated whenever a batch of newly played OKbridge boards was processed. Enjoy !
