Well, if you don't cbet AK and he folds to aggression when he makes no set, flatting with TT is probably +EV.
Let's assume you 4bet AK, QQ+.
Against AK (16 combos), you go check/check when you don't hit, and he folds when you hit. So a bit less than half the time he loses $10 to call the 4bet, and a bit more than half the time he wins $23. And it's much better yet for him when you hit TP but he hits a set. So it's very profitable against that part of your range.
Against QQ+ (18 combos), he loses $10 when he does not hit set but wins your stack + the dead money, i.e. $75 when he hits. That's nearly enough to set mine. Not quite enough, but not hugely -EV.
Overall, i think it's a +EV call against you.
