I like to play with those hands in equilator or pokerstove

So let's give him a little bit wider min 3bet range: JJ+,AJs+,AQo+.
Now here's what we get:
Board: 2h 7s 8s
Dead:
equity win tie pots won pots tied
Hand 0: 54.598% 54.44% 00.16% 32874 98.00 { JJ+, AJs+, KQs, AJo+ }
Hand 1: 45.402% 45.24% 00.16% 27320 98.00 { KsJs }
So 55 times you lose 0.78$ and 45 times you win 0.26+0.15+0.93=1.34$
45x1.34-55x0.78=17.4$ As you can see this is +EV. Of course when playing you don't have that much time to make calculations. So basically when facing stack size like his it's an easy call.
