Raise to 2000.

If she goes over the top you are beat and can fold and try and rebuild again

If she folds you are happy.

If she calls you see the river and might hit an out.

Heads up aggression - rawr

a pair and an OESD, I would have gone all in on the flop - you probably have 13 outs if you don't have the best hand right now.

But I would just call on the turn, your hand isn't as strong now, take the cheap card.

I think that this is a raise or fold situation. You described your opponent as passive, so the fact that she has bet into twice suggests that she has a hand. Whatever hand she has almost certainly beats you since you only have bottom pair. Thus, to win this hand in a showdown, you have to improve on the river.

The real question is whether improving to a straight would be enough. I'm not sure that I would include the diamond draw among my outs because my diamond is of such a low rank. Moreover, if your opponent already has a flush, you could be drawing dead. Thus, I think that you need to do something on the turn to figure out where you stand if you want to play further with this hand.

I think raising her 600 bet to 1500 should get the job done, since that would be a pretty sizable raise and represent half the pot. You would be representing the flush with that bet, and it would be consistent with your flat call on the flop. If your opponent has the flush and it's a good one, you should find out unless she is a truly passive calling station. If she doesn't have the flush, I think that the bet puts a lot of pressure on her and may even win you the pot right there. If she winds up just calling, my guess is that she would check the river to you, and you might get to see the showdown for free.

One final thought, you mentioned that you were worried that your opponent might be setting you up to be trapped. If that is the case, I don't think folding is such a horrible option here. While you have already invested 1,200 in this pot, you still have a fair amount of chips, especially against an opponent who is not being very aggressive before the flop. Under those circumstances, you'll probably get the chance to see a lot more cards and perhaps get a better opportunity to get your chips in.

bonch... we're already at the turn. I agree that flat calling the flop is the right move. But now you're on the turn, the flush has hit, and your opponent has bet into you again. I don't see callling the turn as an appropriate option. You have to try to find out if you are up against the flush. Otherwise, your straight could hit or a third 5 could fall on the river, and you'd wind up losing your entire stack.

Why is flat calling the flop heads-up the right move?

You have the 5d, if he has a flush draw you are ahead - although if he does have too overs you have many outs to beat the overs.

You have a monster hand heads-up why do you flat call?

Responding the situation as presented at the turn I'd raise, but I agree it's a raise on the flop ideally.

I think a call on the flop is the right move because you are almost certainly behind here. This is a passive opponent that has bet into you. In my view, that makes it unlikely that she betting into you with only overcards. It seems far more likely that she has a hand, and you're hand at this point is bottom pair. Hers is probably better, and raising her is unlikely to get her to drop it.

Now you do have a very strong draw, but why pay more than necessary to see the next card? As it turns out, the next card presents you with a great bluffing opportunity if you're opponent has been playing a middle pair or top pair on the flop. The Jd could be a scare card for her, either because it tops her pair or makes a flush. Thus, it seems to me that the opportunity to outplay her and move her off a hand comes on the turn, not the flop (that is, assuming that she is not playing a good flush draw herself).

So a tight opponent min-betting a flop of 865 means you are behind? to what? K8? A6?

Unless she has a set you are at worst 44% to win a hand, and you have a lot of fold equity against a tight player.

Now the turn comes, and you did not define your hand, but you want to raise 1/3 of your stack when you no longer have good pot equity and may be drawing dead? The time to move was on the flop. Just call and hope you didn't let her flush.
