i dont rly see a valuehand in his range he could be raising here ? the guy is a reg. what to do here ? 3bet to 30 ? 3bet bigger ? fold ? call re-evaluate turn ?

defo not folding with the backdoor and the double blocker (he can have AA some as well)
also ur deepish some people will be more inclined to raise sets here still it's rly weird now never really seen this MP v UTG on a board like this from a reg, I'd just keep everything in flatting range on flop including this hand too just makes our range easier to play re-raising is rly about trying to out level him and you don't seem to know him well. Think turn can be a fold against a bet on non heart non Ace since you have all sets all top pairs+overpairs in your range so will be calling with plenty of hands there. Not quite sure about that tho since the blocker's really good here but guess if we have Qx people flat QQ alot pre this deep so the blocker value will be the same. we can probably fold TT JJ on turn more often than this hand right?

I would call and reraise any heart ott if he barrels again and fold all the rest
