re: Poker & Legality of UK poker in private office
Some links re: the story.
The offence they're being prosecuted for seems to be that they're taking a rake from the pot, so maybe this case isn't even relevant to your situation.
Interview with director of Gambling commission re: poker in the UK.
Generally clear as mud. Guidelines not being issued until after the Gutshot case next January. Seems to say that playing poker in the pub is generally illegal, but "potentally legal" if prize money is no more than £4 per head. But no case has ever gone to court, and he implies that the Act isn't designed for this kind of thing.
Don't want to turn this into another pointless "poker is/isn't gambling" thread, but I think that the Gutshot are bound to win. The law applies to "equal chance gaming", wheras clearly poker has a huge element of skill. In fact, Hubert Phillips says in the classic Pan Book of Card Games, that (my italics):
"Poker is not only one of the most difficult of all games to play well, but it has a higher skill factor than any other game played with playing cards. By that I mean that, of all the games with which the card world is familiar, it is the one at which good players can be most certain of winning against bad players."
