[loicve]

Player 4 is VPIP 14 PFR 8 Agg% 38 (37 hands).
What do you think is the best play here and why ? Thanks !!

Reload prehand, raise more preflop. It is really weird to see the nit donking like this. I would expect him to c/r a set given the relative position. When I get confused, I tend to call down (probably calling 2 barrels but not 3).
