It's a poker community.
The forum is the heart of it, ideas are discusssed, experiences shared etc.
The highlights are the hand analysis board, frequented by some of the finest minds in UK poker, and the live tournament updates, info as it happens on some of major the poker tournaments going on.
Any specific questions people have, you can usually get a decent and knowledgable response from someone on here. A fair bit of off topic chat too.
The main site offers poker news/articles and general information. The news and information is ok, some of the articles are a bit dodgy.

They also have a card room, part of the Tribecca network, where people who enjoy the community are encouraged to play. Tournaments are run, theres even a league or two with added money prizes.
Then there's the blonde bashes...
