post-flop hand

[Dallara]

Any comments, particularly on the flop call? Normally I would probably raise here, but I tried calling figuring to see what UTG+1 did. After the turn blanked and villain led out weakly, I figured I could take it with a turn raise. How do others play it?
The river was obviously a nice gift, but I'm probably check-calling a moderate bet if I don't get so lucky on the river.
