Yoru raising in general seems weak, I do pot sized bet after pot sized bet here. $6 on flop, $18 on turn, all in on river or another $18 if you want value. The wonderfull thing about this flop is hands like AK/AQ won't know any better, they can't really put you on trip tens, and trip aces are out of the question.

Probe bet after probe bet allows him if he has AQ/AK (q or K is hearts) to draw for a reasonable price. and considering your UTG if river comes heart you must release your hand to just about any raise.
