Commerce 10/20 Freerolling Math Question

[lapoker17]

Not that interesting a situation, but I was hoping you math guys could shed some light on this for me - I'm interested if Villain made a proper +EV call, and although I'm kind of a math guy, I don't do real math with formulas and stuff.


Crazy table, 5 handed, 10/20 no cap.

Maniac (20K) raises to 150 as he does 80% of hands, 2 callers to me ($5000) on the Button with A [img]/images/graemlins/spade.gif[/img] 4 [img]/images/graemlins/spade.gif[/img]. I call.

Flop is J [img]/images/graemlins/spade.gif[/img] Q [img]/images/graemlins/diamond.gif[/img] T [img]/images/graemlins/spade.gif[/img]

Checked to Villain ($5000) who bets $400. I call it's heads up.

Turn K [img]/images/graemlins/heart.gif[/img].

Villain bets $900, and I move all in.

He knows I'm freerolling with the spades. He has A [img]/images/graemlins/club.gif[/img] K [img]/images/graemlins/club.gif[/img] Is this auto-call for him?
