JJ in the small blind
 

unimpressive MP limps, typical Button (50/9/1.3) limps, Hero raises, fold, call, call.

flop KQQ bet, fold, raise, call.
turn A bet, call. (folding to a raise)
river blank check, check. (check/folding)

Re: JJ in the small blind
 

Looks ok to me, looks like he has some thing like KT, or a small pocket pair, and the A combined with your bet scared him.

I check fold the turn.

I also bet/fold this flop much more than I bet/call.

I think you need to pitch it on this flop. You're drawing to around 3 outs with the backdoor, not near enough to continue.

Re: JJ in the small blind
 

I generally fold when he raises the flop.

How often is he bluffing here?

It is possible he has JT for an OESD but less likely because you hold two Jacks. Would he raise an AT gutshot? A T9 gutshot is even less likely to raise. Maybe it's a free card play with AT, but I don't think you'll see that often enough on this scary flop after you raised preflop and bet out on the flop to warrent continuing. An exception might be if he thinks you will bet with an underpair. What has he seen you show down lately?

On the turn, if it had an OESD or the AT gutshot, he either made a straight or paired his Ace. I think the reason he called your turn bet is he's afraid you have a Queen and he didn't make a straight. He probably has a King. Another indication of that is that a Queen would often not have raised until the turn.

I think if you call the raise on the flop, it would be better to chk/fold the turn UI.
