1/1 game, been kinda nitty but coming alive.

Hero - Looks like young geeky white guy. TAG, not shown down a hand yet, won one pot raising turn. Stack ~350

Villain 1 - old man wearing headphones, probably most active player at table. Normally opens for 6/7bb. I’m guessing ~70/30ish. Slowplays big hands OOP but calls with a lot of crap as well, mostly one and done if the aggressor. Stack ~200ish

Villain 2 - unknown limper, 25ish, looks kinda dirty, guessing 20/0ish. Limp/called AK pre and check/called down TPTK, bought in for 50, stack ~120

OTTH. V1 opens for 10 UTG+1. Two fish call, I call CO w 78, V2 completes in B.B.

Flop - A64
V2 leads out for 20, V1 calls, 2 folds. Hero?

What’s your decision and what’s your plan? Thanks

Call and see a turn IP. Raising here is going to yield way less EV imo and is pretty spewy, esp with Ac not on the board

Yeah just flat, you probably aren't getting rid of V2 by raising and you're a small dog against everything. No point blasting the others out of the hand. One other thing in favor of flatting is that you can probably expect V2 to bet small again OTT, allowing you to easily get to the river.
