Hi everybody. I want to ask about one live plo game hand.
6 handed 10-10$ deep game.
Stacks are below before hand.
SB-4500$
BB-2200$
Hero-3600$
CO-1500$
Btn-2100$

Hero A◇Q◇Q♡5♡ opens HJ 40$, Co calls, Btn raises 160$, Sb calls, BB calls, Hero calls, CO calls.
Pot(800$)
Flop: 3◇4♡5◇
CO bets 800$, Sb raises 4000$? Action is on Hero.Does Hero have to call all in with flush draw?
