Table info: Hero has been sitting at the table for a little over an hour and has been very active. Doubled though a reg the 2nd hand w/ overpair vs top pair, and called down a weak 3 barrel semi bluff with 3rd pair. No other showdowns to speak of. A bit of an unknown at this table I think...

V1(sb +/- $325) I have a little history with this villian. He is the type that will button straddle 5/10 every time and ruthlessly defends it. His is also the type that will limp a straddle and call a 3bet with a very wide range and is not afraid to play back at you with not much of a hand. I stacked off to him a couple weeks ago when I raised his $10 B straddle with QQ, he calls we get it in on a low flop and he spiked 2pr on the turn.

Hero(UTG+2 $450)

V2(MP $145) Not much of a read on this player at all, not nitty by any means.

Folded to hero who raises $10 w/ AsKh, V2 3bets to 45, V1 calls, hero calls

Flop AcJh2d
V1 donk leads for $40, V2 tanks for a second and goes all in for $100

I'm super lost here was the flat call preflop bad? I figured with my image it would disguise my hand a little bit

If they're that loose just jam it in pf IMO. As played I'd probably call the 100 and probably fold if V1 jams it in.

don't fold, at any point

jam pf, V1 never has AA KK here
as played Jam if he is loose, fold if he is tight
