the villain may have AK and called on the flop thinking my bet was weak. He could be trying to take the pot away from me. At this point, I'm only behind a 3, 55 or KK. He would have raised or limp raised with KK and he wouldn't called UTG with a 3 unless it was 33 so that's unlikley. Therefore, I'm only afraid of 55 and I'm ahead of AK or him trying to push me off the hand.. What do you do?

that's interesting.

I like your bets on these streets a lot. there's no flush draw, and his limp/call utg rules out a straight draw or A3

his raise on the turn is strange - i don't think that the flopped quads would check raise that much, and i kind of doubt that 55 would either - neither hand has much (or anything) to fear or protect against.

Even still, because of the size of your bets, he's can't possible put you on AA.

I think you're ahead here, and can get the most money out of him by calling here and letting him bet on the river. if you push this turn you're only getting called by a hand that beats you.

I think folding it out of the question.

On the river, i'm not sure if i'd push, but i think i'm calling any bet here, since the only hand i'm really afraid of from a tight opponent is 55

right, i would also value bet if he checks to you on the river.

2 things... his call PF, call the flop, checkraise the turn smells like trips or a boat to me... But, if you have a good enough read on him to KNOW he doesn't have a 3 or KK, then I would push here... You got AK dead... If he's got 55, that's just bad luck, and still have outs if another A or 3 hits... This would've been the best flop for him to hit, and the reason people call PF raises w/ small PPs... You pretty much know he's gonna push the river, since he's got like $25 of his $55 in the pot... I would push and put the tough decision on him...

I do think the weak-ish flop bet makes things a little confusing. I'd be more inclined to overbet a little (like $6) than underbet there in order to see what we have.

As to the further progress, I think Long makes an excellent analysis.

Results:

I tricked you guys a little and reversed the players. I was the villian and had 55 and obviously got the monster flop I wanted. I hoped that he had an overpair. He went all in on top of my turn check raise. I called just hoping he didn't hit his two out and was pleasantly surprised to win a big pot. What are your thoughts now on my play UTG to trap this guy for all his money?
