pre-flop is fine, i like leading the flop, but i would make the 3-bet bigger. i'd make it about 18 or 20 to go. you're only making him call 7 more, which is very easy to do with any kind of draw.

when he 4-bets, i think i'd push right there. the problem with flat calling is that there a lot of scare cards for you - any K, Q, or heart. you don't know which of those he needs. is your plan on the turn going to be to check-fold if any of them hit? to check-call? either way, you risk either paying off a winner or getting pushed off your hand. just raise all-in on the flop.

there's a decent chance TT, JJ, or (especially) AA would have raised preflop, so the last hand left you really don't want to play against is KQs.

you flopped top 2 pair. wouldn't put him on a set since he probably would have raised pre-flop. could have flopped a nut straight. how was he playing before this hand, was he aggressive. if i had a straight with so many players you didn't pot bet the flop so he could put you on a flush draw, but when you reraised him and he didn't fire big back i'm thinking he has 2 pair as well since there were 2 hearts i wouldn't want you to catch your flush. i think you should have pushed.

I was unsure of how to handle his last reraise. My plan was to call and push if a scare card didn't come.
