Villain in bb w/120bb
Hero in sb with 105bb
Hero raises to 5x
Seem like you 4-bet to around 40BB and got called, which then created an 80BB pot with 60BB left behind. This is an extremely awkward spot, unless you have aces, so mainly I would simply not do this. I would either just call the 3-bet and hope, one of the limpers come along, make a very small 4-bet or move all in. As for Villains range, it should obviously be very strong, when he puts in 40% of his stack preflop. QQ+ or AK. Something like that. Unless he is a fish.
