table knows his intent preflop, so they have to put him on a pretty tight range of hands... AA/KK/AK/AQ/QQ/JJ/1010 most likely

He bets out 1.2k into a field of 6 players... would he seriously do this if he had whiffed the flop with his underpair? most likely not, so the table can narrow his range even further.

He gets flat called, given the information freely passed around preflop?

Heros dilemma is that there is only one draw out there... 10J.. the rest of the pro's calling hands are going to be made hands, and the pro *knows* what the UTG donks range is, so any made hand is most likely going to be a set/2 pair
for villain

I don't think hero can put enough confidence in the hope that villain has 10J, to justify calling here with one pair.

one thing that is quite important is the villains relative position to the UTG donk, as the further away he is, the less likely he would be to have KK/QQ...

getting 2/1 here... its most likely he is looking at 10J or QK/QQ/KK... against this *likely* range, id lean towards advocating a fold for hero
