This hand was played on PPPoker and the game plays very loose preflop. The only available stat is VPIP the original raisers was 59/%. Preflop I think the call is fine with the suited ace and connected side cards. On the flop is where I struggled. I checked bc I was OOP to everyone and was planning to check raise if someone bet. On the turn I pick up the nut flush draw along with the two pair so I bet and when raised I 3 bet all in. My main question is on the flop should I be leading into 3 opponents? On the turn I think GII is fine but am open to any other suggested lines.
