I cant resist, After a little thinking I think I have come to a conclusion about which line is better between, raising the turn and betting the river, or raising the turn and checking the river.
If I raised this turn and the UTG player called, I would check the river if i dont improve. Given the way the UTG player has played his hand preflop+flop he is verly likely to have a big over pair AA,KK,QQ. Since he just called the turn he cant have KK, so his most likely holdings are AA and QQ. Given that the hero is a 2-1 underdog against this range, I would check the river, now if you add in other hands like JJ or TT it would swing the river to a bet, but with no information on the villain, I would stick to my QQ-AA read and check the river.
