this is really tough for maximisation.

If this wasnt such a nitty game id open push here, we'll get the guys stack if he has a multidraw or a set IMO.
But, we want to try and keep some of the money behind in the pot too.
If we think he has a set then i think calling isnt horrible considering board pairs something like 20%? time on turn, so we can get him all in on most turns oop anyway.
Saying that, i think its important to take this guys stack and forget about those behind because as everyone notes your hand is ultra strong but a but vulnerable.

I like raising to $35 and calling a push or pushing any turn regardless of it being a heart given our read he has a strong hand.
