He's a chaser who lucked out - he calls a pot sized bet (almost) with a gutshot and drawing to the non-nuts flush draw. I don't think anything but an all-in might have got him to go away - but even that might not have done it.

As far as the turn goes... well you say that you didn't put him on the flopped flush (he would slow play) but with his bet of less than half the pot it looks like he's trying to controll the bet amount to get better odds to hit a draw - he must be pretty sure that his J is the best club out there. Then the straight hits and he bets the farm on the turn - warning signs.

At this point the only thing you can beat is a Q with a worse kicker - or a worse pair. He asks you to call a pot sized bet (giving you 2:1 on a 5:1 shot) and you pay him off. You say you missed seeing the gutshot (it happens) but the odds still were not right for many of the other hands he might have had. You only had tp/tk - with a DRAW to the nuts and maybe an A if you put him on 2 pair or the 3rd queen (which if he had a flopped set would give him a boat).

A gutsy move (or dumb) on his part - he obviously didn't put you on a made flush. But you where not pot comitted so let it go.

Just my thoughts.
