I would have folded the flop. However, as played, I would have bet the turn and folded to a re-raise. I haven't seen too many players check raise in live 1/2, and her check seems more like weakness to me than a trap. But you were there and you are the one who has the "gut" feeling.

I definitely can't imagine her checking the river with a made hand, unless she's extremely tricky or extremely bad. She needs to get money in somewhere if she wants to make money. If she really thought you were going to bet and she had a made hand, she should have put a little in the pot hoping you'd raise her or at least call. Why give you the opportunity to check behind her set or two pair (although I hate two pair)?

Also, when people do what you did (acting as if they are going to bet), it's often a bluff.

As played, I probably would have bet river, too, and folded to a re-raise. Again, you were there....

You did get away cheap, though, and you might be ahead.
