This may well have been discussed and if so please direct me to the relevant thread.

I'm looking for advice on a situation that I've encountered more than once in the last week and I'm not sure how to play it. Here's an exemplary version of the problem situation: I open raise, one player calls behind me. We get a wet board, with a possible straight: I have the nut straight draw and the third nut flush draw. I check-call; we see a brick on the turn, and I check-call. The flush comes on the river. I have my opponent covered. Do I:

1) Bet all in and hope I'm leading and that he's tempted to look me up?
2) Bet half my stack and fold to a raise?
3) Check and call any bet, hoping to induce weaker hands?
4) Check and fold to most bets?

I can make an argument in my own mind for each of these. And, yes, I do know it's "villain dependent," but let's say you have no history. What now?

#3 is generally going to be fundamentally correct, but #4 can be an improvement against nits, and #1 or #2 against stations.

is this a no limit omaha game? u also need to give more details about the hand itself. position/stack size/history with villian etc.
3 and 4 seem good and 1 and 2 sound terrible to me without any more details

Why are you raising pre and then going into c/call mode with a strongish draw?

I am wondering this as well. As played i guess continuing the check call route is probably good vs unknown. But i know nothing

Well he didn't say at all what the texture is like, there's a huge difference between 9TQcc and 578cc. Playing passively with our range on the latter flop that doesn't hit us nearly as much seems reasonable even with strongish draws.

And I didn't say he was wrong to c/c, just asked why in this case he did since based on the limited information betting seems preferable to checking!

Also at 25NL I don't worry so much about balancing my range as much as at 100NL. I'll quite happily bet my strong hands/draws and not be worried about being exploited by that many opponents when I opt to check flop instead.

1) Bet all in and hope I'm leading and that he's tempted to look me up?
-you might make him fold smaller flushes, straights and sets

2) Bet half my stack and fold to a raise?
-this its not even close, give him a chance to call with his questionable hands, the chances of him reshoving as a bluff are countered by the times he calls with worse

3) Check and call any bet, hoping to induce weaker hands?
-induce him to bluff into a flushed out board? VERY villain dependent

4) Check and fold to most bets?
-you can't win if you fold
