This is also a repost from SSLHE, but it made at least one person smile.
My first time playing was 2/4 [LHE] live in Vegas in 2002. A group of 10 of us were walking back to Mandalay Bay and stopped to rail the poker games at Luxor. They were playing this weird variant where everyone only got 2 cards and then there were 5, face up, in the middle of the table. We had no idea of what was going on - we were vaguely familiar with stud and draw poker, but to be honest half of what I knew came from the poker scenes in Star Trek (TNG).
At some point the floor asked us whether we wanted to play - they'd set up a new table for us. After some discussion about how much we had to put down, etc, etc, we agreed. I actually disagreed at first, because I had actually hit a gambling stop-loss earlier in the day. I was down $100 already (don't laugh, that was a lot of money to me back then), but eventually my friends convinced me to fill up the table so nobody else could sit down.
Strangely enough, because of this, I kind of stumbled into some sort of basic strategy - essentially, I refused to play unless I had a "good" hand, which I thought was {22+, AJ+} based on good 2-card hands in pai gow poker. KQs? Pfft, king high, fold. 98s? Are you insane? 22? ZOMG PAIR MUST PLAY! (Actually, 22 10-handed isn't bad, especially since I was set-mining with anything below KK. It's just funny how excited I got at 22 because ZOMG PAIR!)
Most hands were 9-way, with a few 8-way hands when someone besides me folded. I think I was also one of the few to understand AKs was better than AKo, but it didn't really matter because I was playing so few hands and never raised anyway. If checked to me, I'd bet (or donk) anything worth a bet, otherwise, I'd check-fold mostly. I think in 2 hours I won two big pots, one was with a set (to which one friend commented to another, "what do you think he's betting with?") and the other was with some pair of aces which I check-called to victory (I didn't quite grasp the concept of "top" pair, I'm almost positive at some point I folded AJ on a Jxx board because jacks are only a medium-sized pair). Down $2 overall, which I think put me in 3rd place (obv because of the rake and because the dick of a dealer told us that people usually tip 5-10% of the pot ... an offense that we've never really forgiven them for).
The next year was the year Moneymaker won the WSOP and poker became cool. We got a little bit of jealousy from the people who missed the trip when we bragged that we had played Texas Hold'Em ... in Vegas!
