Good, bad, ugly? Sorry if it's standard, I'm trying to make the adjustment to 6-max. Heck, I hope it's standard.

Yep. Looks standard to me. You're folding at any time if raised here vs. a guy with those stats.

i don't know if a check/call or a bet/fold is better on that river. its probably close.

I mean, c/c river was my first instinct, but if he's so passive that he won't bet a missed flush draw, then it's obviously bad. That being said, some passives do bet when you check to them, as it's their only way to win the pot.... I dunno, value bet is probably best.

Continue betting. I hate Limit!

You said that in both responses! Why are you in this forum!(?)

I continue betting and hope he looks you up with ace high

I think c/c is horrible, here, against a loose-passive player. B/F.

I have a question for ya'll... how often and against what kind of opponent do you river raise bluff? While I agree the bet/fold line is appropriate in this case, I see that line advocated alot in every forum, and most of the time, it makes sense. but at the same time, I think a player that is an aggressive value better, who folds often to river raises, has an exploitable weakness. how do you recognize that weakness, and how often do you exploit it?

Well you see the thing is, even though everyone advocates b/f, it is rarely done, and especially less often by our opponents. At low stakes, our opponents just suck really hard and are never folding anything. If you have a player who is going to bet/fold in a correct spot, you should probably just be switching tables if you're at anything lower than 3/6.

Then, once you get up past 3/6, everyone is bluffraising all over, so everyone turns into a showdown monkey (I showdown just less than 40% of the time and I think anything less would be exploitable). So the answer is that I bluffraise the river quite often, but the profitability is not that high, because nobody folds. Luckily, in big pots, it just doesn't have to work that often to be slightly profitable.

I do agree though; If everyone b/f as much as is recommended, they would be incredibly exploitable. I would raise and b/3b the river alllllllll the time. It would be awesome.
