Given the last-hand-of-the-night read the only semibluffs I would include in V1s range are 8
9
and double overpairs. I don't think he wants to be messing around drawing to non nutted hands.
Tough spot.
If we flat flop how often will V1 raise? Always with T7 and pretty much never with TXXX right?
I risk the 565 to try to see the turn, expecting V1 to not be overaggressive in a protected pot on the turn and river.
