((Bug?) Difference Between AI Adjusted and CREV's EV

[4StarGen]

I started to work with CREV, and I've noticed PT4's AI adjusted and CREV's EV are different.
In this hand for example:

PT4 shows -82 BBs in AI Adjusted
Here's the calcs from the CREV developer:


Hi Matthew,

All I can tell you here is that the calculation in the CardRunnersEV tree is correct.

At the shove decision, BB has 139.48 in his stack left.
He shoves.

If he loses, his remaining stack will be 139.48 - 119.28 = 20.10 (this is the difference between the two starting stacks of 139.48 and 119.28).

If he wins, his stack will be 119.28 + 139.48 + 13.4 - 2 = 270.16
Basically, he will have:
- SB's starting stack (119.28)
- plus his own starting stack (139.48)
- plus the starting pot (13.4)
- minus the rake (2)

Given that BB's equity is 16.768%, his final stack will be:
- 20.10 in 83.232% of the cases
- 270.16 in 16.768% of the cases
That makes his expected stack 16.768%*270.16 + 83.232%*20.10 = 62.11

Given that if he were to fold instead of shove he would be left with 131.04, the EV of shoving is 62.11 - 131.04 = -68.93.


Why is there a difference?

a little update... the above method used the simple 2BB rake for HU pots, while my hand was a six max, with a rake of 8BB. This isn't changhing the fact Hero has -69BB EV instead of what PT4's -82

Given that if he were to fold instead of shove he would be left with 131.04, the EV of shoving is 62.11 - 131.04 = -68.93. Why is there a difference?

CREV is calculating the EV of shoving vs folding and that isn't the same as your adjusted all-in equity.
