ATo UTG vs 3bet MP

Well it's certainly not worth raising AT here vs a range that's 3-betting your UTG

If he checks back w/ 88 then you're going to lose a bit of value but on average ATo isn't great here vs a range that's 3-betting a UTG raise, you're only 51% favourite on the turn and that's vs a fairly wide range which this guys probably doesn't have

In terms of bluffing if you think he's going to bet/fold all his underpairs then you have to have some bluffs on this board and 66-77 are the worse hands in your UTG range, aside from the odd 9 :heart:T and 8 :heart:9 :heart:, which you probably dump the flop on anyway, so given they're the bottom of your range then bluff raisign them isn't horrible.

I agree on Boomers Post. You should not only consider your EQ of 51% but you should ask yourself: what are his worse hands you might get value from if you'd checkraise.

There is not only one hand you get value from. Either he does have KQ AJ AQ AK or a set or he does have JJ TT that he checks the turn with and against Pocketpairs he is drawing dead.

If we don't consider your gutshot-Outs it's kind of a wayahead/waybehind -Situation. It means either you're kind of far ahead and he's drawing pretty thin. in case he's got a Pocketpair like 88 99 or you're drawing thin against a Set or AQ etc.

So in such a case raising doesn't achieve anything. check/call Turn and showing down the hand by another check/call is the only reasonable play. Well played
