re: Poker & $5 NLHE 6-max: flopped a pair with pair on board.
I like JTs too, maybe not one of my favourites UTG but it depends on the table makeup really.
Couple of questions I would ask myself on this one. Firstly, what does he flat with on the flop once you've led out? That depends on the villain, and his stats - would he be likely to see another card with T9, KT, and other drawing hands? Has he hit the Q and wants you to catch up because he doesn't think you've hit hard enough to get 3 streets of value from you?
The second question is why the raise on the turn. The 6 doesn't really change anything, unless he has hearts and has just picked up the draw. There are only two types of hand I would really put him on - a drawing hand, and he's going to try and take the pot down now as he doesn't think you've got a queen and his draw has missed (he may have picked up flush draw too, so is happy if you flat) or he has the queen and your 2nd bet means he thinks he can get more value.
Personally, given the strong reraise (at micro stakes I normally find those who want you to call will raise 2-2.5x as opposed 3 to encourage the call) I think he's got a weak hand which he could be pushed off by a shove by you, but that's a pretty ballsy move.
Just my opinion
