Some people at work play poker (no limit Texas hold 'em) every Friday at lunch and I've joined in for this "season." It's the first time I've ever played and it's been really fun so far. I started back in January so I've played a bunch now and I think I'm starting to get better at the part of the game where you try to figure out what people are doing. The cards and the chips are really just tools for determining what everyone else is thinking. Anyway, I'd say I'm not doing too bad. I'm 7th overall in the standings (of about 15-20 people) and I just made a huge gain by finishing 2nd in today's event.
Sometimes people also play after work, but it's much less formal and serious and everybody lends chips when you run out so there is no real worry about losing. It gets silly fast. I find I don't enjoy it as much because there is nothing riding on it. It's much more fun when you have something to lose, even if it is just meaningless points in a contest with no prizes. I don't know if I could handle playing for money though. Way too stressful!!
