If you were heads up preflop with him it would of been 60/40, but after the flop it was actually a coin flip, so the preflop call by him was questionable, imo, once he was in with that flop, can't blame him for the play. Think you were still a very slight favorite, but not more than couple percent. I've noticed playing live you get a lot of callers with raises for some reason, maybe its the level i play at. I once raised aabout 6X bb (your raise i believe) preflop and got 5 callers, i had QQ. Flop comes up all rags, guy pushes and has something like 6 3 s, and hit 2 pair.
