I still think a flat call isn't a bad thing here....Your raise is irrelevant to deride....this only affects Mboyd. So you can raise and get Mboyd out...or call and try and keep Mboyd in. So the question now becomes, do you want Mboyd in or not. What are his likely holdings....PP and flush draw. I think PP is more likely because of his bet on the flop...therefore I want to try and keep him in to take more money off him on later streets...2vs3vs4 way is irrelevant here - do you think you are way ahead of Mboyd...I think so, I try and keep him in drawing to 2 outs. Flat call and bet the turn.
