Trips on the flop, would you fold?

[EnderW27]

I have one general question and then one specific question.

I'm in one of those amateur games they have weekly at the bar. It's a free entry thing with only the first place person taking home a prize (and an entry into a larger tournament). There are some truly awful players there, but the blinds go up so quickly, it eventually comes down to luck. I mean, they have two tournaments a night and they need to wittle 80 people down to 1 in 3 hours or less.

I play for fun with my friends. I drink beer and have pizza. So, truly, of all the poker skills I could learn, this is one of the lowest on my list. But, nevertheless, what's a good general strategy for a tournament with such a huge luck factor built in?

Second question, from a specific situation that came up last night.
Let's say you're playing with a woman you have a total read on as non-tricky. She doesn't check raise, bets when she has something good, calls with a draw, folds with nothing.

You have A5o on the button. Six people in the pot with blinds at 50-100. Flop comes down AA6, two clubs. She bets 300 into you. You are almost 100% sure she has the other Ace.

Would you fold this?
