All players in the hand are losing players and can have a very wide range of hands (all have above 25% VPIP). The player pot betting is a big losing player according to sharkscope, but I havent got hand stats on him.

Calling is obviously not done. I Pushed the hand because I figured he'd have a high Ace trying to protect its hand from flush-draws. But with the amount of players involved in the pot, I think I shouldve folded due to the increased chance of somebody having a flush/set.
Would the situation change with only 3 players in the hand?
