<font color="red">Hero raises to $8.00</font>, MP calls $8.00, CO calls $8.00, BTN folds, <font color="red">SB raises to $23.00</font>, BB folds, <font color="red">Hero raises all-in to $300.75</font>, Two players behind to act with full stacks.

Do you guys think this is a +ev play? The two guys behind me show these stats: 20/13/1.6 and 26/15/1.5

The short stack who raised is a huge donk and was just donating money to the table. I wanted to isolate him but I didn't want to just call and play a big pot oop. I think if the guys behind me had KK or AA they would have raised. They were playing tag the whole time.
