I'm not sure I have much to offer here, but as you're looking for inexperienced posters...

Based on your line about villain's slow-playing, my first inclination is to take the free card for the flush draw. Then I looked again and saw that if villain has a slow-played A, we're screwed. (Reading the board correctly can be helfpul.)

I'd really like to know if villain would bluff check/raise the turn here.

So anyway, I think the turn might actually give us the best hand and we should bet for value. Since villain is labeled as LA-P, we can safely fold to a check/raise.

EDIT: After thinking some more, (and reading responses) a turn bet is only for value if villain will call with less than Q-high, or fold Q-high.

Here are the options with a turn bet:
1) we bet, villain raises and we have to fold = -1
2) we bet, villain folds = +0
(we gain nothing because we had the better hand anyway)
3) we bet, villain calls = +1
(assumes villain will raise with an A or K)

So the question is: Which of these is more likely? My brain hurts from too much thinking, but I'm tempted to say that checking behind on the turn and calling a river bet is a better play.
