KTo in BU vs MP raise

By the opponent being active do you mean high vpip? Loose postflop? Splashy?

The problem with the overcards on the flop is that you don’t know if they are good when you hit a pair, hitting a pair can make you easily dominated

On the turn the T should be slightly better for your range , villain is betting polarized. Versus a polarized range you dont want to do much raising at all , I’d probably call turn but not loving the spot

My charts say
KTo Borderline hands, only call versus loose players that open wide

KJo would be a call AQo would be the lowest off suit i'm 3bnetting here, i guess that's much of a muchness though it depends what charts your using they all differ slightly. (not sure how GTO charts differ but they do). As played i fold the flop you have 2 bare overs id also want some sort of backdoor potential to continue.As played id call turn and call decent rivers if you think they are aggressive enough to tripple barrel some bluffs.

Against a active player I would consider to 3bet bluff this. KTo hasn't to much playability post-flop or you hit top pair with the T, broad way draw with a Q and J on the flop or 2 pair or better.

If you are floating the flop and villain continues like now i would just call the turn and her-evaluete the river. if you raise you isolate yourself against better.

imho never a call pre. fold or 3bet, because of the bad playability and the reverse implieds when getting called. as played fold flop w/o equity. turn is never a raise - in addition to FDs, he's representing all sets, all overpairs and the nuts. your range on the other hand is capped. overall you only have 36% equity against his turn range:
TT+, 55-33, A2s, K8s, 98s, 87s, 76s, AdKd, AdQd, KdQd, AdJd, KdJd, QdJd, AdTd, KdTd, QdTd, JdTd, Ad9d, Kd9d, Qd9d, Jd9d, Td9d, Ad8d, Qd8d, Jd8d, Td8d, Ad7d, Ad6d, Ad5d, Ad4d, Ad3d
