$0.5/1 on Stars.
My stack: $140; opponent: $100.

Opponent has joined table about three orbits ago. I have seen him raise twice, once with QQ and once with JTs.

I have JJ UTG and limp in. A couple of callers, and opponent (button) makes it $5. Folded to me, and I call (pot about $13).

Flop: 29T rainbow. I check, opponent bets $5. This seems weak to me, so I checkraise to $15. Opponent calls. At this point I'm confused. I checkraised to find out where I'm at, but what does this call tell me? What do you put my opponent on and what does he put me on?

Turn is a 7, no flush draw possible. Now what? Pot is $43. I bet out $30, and he flat calls.

River: Q. I check, opponent checks and takes the pot with AA.

I do regret my turn bet, but I sensed weakness and thought I could represent a strong hand. Probably better to check the turn? How much would you call there? Should I try to bluff the river?

Not much you can do here I think. The next time you have a set in a hand against him, play it the same way.

He played his hand well (other than the strangely small flop bet)

Right. Missed that part about the JTs raise earlier. Darn it.

Heck, then QJs is possible for him, giving a big straight draw on the flop. If that's a serious possibility then you have to bet the turn.

I guess the extra $$$ he got out of you with his aces is precisely why it can be worthwhile to sometimes raise with JTs! Too bad it had to happen to you.
