First Hand:

V1 is older lady, very weak calling station. Any touch, any draw, for any amount. Exceptionally spewy. Impossible to overstate. Truly atrocious player.

V2 is middle-aged guy who seems otherwise pretty solid, but looks to hit in big pots without correct prices. He recently flatted a big-ish 3 bet from V3 (60-70?) with 89ss and like $250 behind. Flopped trips and took down a decent pot on a 599T board (ended on turn). V3 didn't show down, but claimed he had overcards, which is plausible and I believe him.

V1 has ~$275, V2 has ~$350, V3 has ~$900, I have ~$600

EP raises to $10, V2 calls from MP, V3 calls from the button, I 3-bet to $50 (sizing?) from the SB with AcKh, V1 cold-calls from the BB, EP folds, and V2 and V3 call.

Flop comes Ks4h2h. I c-bet for $140 (sizing?), V1 snap shoves for her last $225, V2 does a deep sigh, mutters about needing to go home, and shoves for $297. V3 hates to fold, but does. V2's speech is really bad for me, I think, and its the only thing that gave me pause, but getting 6-1 I have to call, right?

Hand 2 is about 90 minutes later, V4 has ~ $400, V5 has ~$450, ~V3 has $900, I cover.

Straddled by V3 to $4, I pick up QQ UTG. Open to $20, get called by a nit UTG+1 (V4), and another unknown (V5). V3 flings out 4 greens to make it $104.

V3 is younger guy, very aggressive player. We have a little bit of history, I've picked him off on the river with bluffcatchers a few times now (not today), so he seems to have slowed down a little against me specifically, but runs over the rest of the table usually with big 2nd and 3rd barrels against scared money nits. Definitely a winner in the game.

V4 is super nitty, and after I tank for like 15 seconds both he and V5 look done with the hand.

I'm not sure what to do here. Folding seems out of the question, and if I call, I'll be guessing on any board with overcards. I also just straight up think I'm pretty far ahead of V3's range here. So I think a 4-bet seems right, but not sure of the amount, or a plan for rest of hand...
