EV of Allin:

You put him all in for his 300. There are 6 combos of TT, JJ, and KK. There are 3 combos of AA and QQ. There are 12 combos of AK. So 36 total combos. He folds 6/36 of these or 1/6. So 1/6 of the time you win 100+30=130.

5/6 of the time he has JJ-AA or AK and will call you. Against this range, you win about 29% of the time and lose 71% of the time (pokerstove). (.29)(330)+(.71)(-280)= -103.1.

So Total EV when you move all in is (1/6)(130) + (5/6)(-103.1) = -64.25

Folding has an EV of 0.

I'll try to do the EV of calling later. It's the most difficult though.
