Playing 2/5 where max buyin is 500 with max bet 500 and 3 bet cap

Hero 800, v1 good player young aggressive Asian who lost most of stack vs all in with v2 stack 65, v2 older aggressive white guy 650 won hand with v1 on opened ended straight call on turn, v3 350 Older Asian that likes to play draws and looks to trap all the frigging time, v4 younger white guys who doesn't have much to his game bought in for 300 and is down to 180

Preflop v2 limps utg, v1 limps mp, hero limps mp w/ 88, v3 raises to 15 on button, v4 calls from bb, v2 calls, v1 shoves all in for 65, hero calls, v3 calls, v4 calls, v2 calls. 325 in pot Preflop.

Flop 10s8s7c v4, v2 check. I take a look at v3 on the button counting out Chips. Hero checks and then button v3 checks. ***!

Turn (pot still at 325. V2 585, v3 285, v4 115)
Qs completing flush. Im think fold to anything at this point. Action check, check, check v3 on button shoves for 285. V4 all in instantly, v2 tanks for about 3 minutes and calls. Pot is now 885. V2 still has 300. Hero?

Fold or raise pre when the raise is to 65, you aren't deep enough to set mine.

Checking the flop, come on, you already know that's bad.

Looking at stacks on the turn, do some math, I think you can't fold due to your outs to a boat vs the amount of dead money in the pot

You must bet the flop. I'd bet ~$150, and call if someone decides to shove. Also, in my experience if someone grabs chips while they are waiting for action before them, most of the time they don't want you a bet. Classic tell there
