Simple fold eq hand
 

I find that I too rarely get down to analyzing the math behind fold eq situations, so please correct any mistakes I've made here.

UTG: $216
MP: $237.10
CO: $66.20
Hero (BTN): $243.70
SB: $196
BB: $219.65

CO posts $2
Pre-Flop: 8[img]/images/graemlins/spade.gif[/img] 8[img]/images/graemlins/club.gif[/img] dealt to Hero (BTN)
UTG folds, MP calls $2, CO checks, <font color="red">Hero raises to $11</font>, <font color="red">SB raises to $38</font>, 3 folds, <font color="red">Hero raises to $243.70 and is All-In</font>

CO poster is obv. horrible and doesn't have a hand, UTG+1 is loose/terrible.

My stats/notes/reads on SB says he's 19/14 and he 3-bets too much preflop. I'd been playing 30/20 at the table, so if he's paying any kind of attention to stats/the table he knows I'm raising anything playable here.

Now, I think he needs JJ+/AK to call this, against this my hand is 33% and there's roughly $50 in the pot, so:

EV when called = .33 * 400 - 200 = -68
EV when he folds = 50
0 = X * -68 + (1-X) * 50 = -68X + 50 -50X = -118X + 50 &lt;=&gt;
118X = 50 &lt;=&gt; X = .42

He needs to fold 42% of the time to make this play profitable, right?

Corrections to math and comments on the play are welcome.

Hope this doesn't turn out to be one of the bad posts I berated in the (nc) thread [img]/images/graemlins/smile.gif[/img]

EDIT: Just gotten corrected, more precisely:

EV when called is .33 * 398 - 185 = -52
EV when he folds is 55

X = probability he folds

0 = X*55 + (1-X)* -52 = 55X -52 + 52X &lt;=&gt; 52 = 107X &lt;=&gt; X~= .49.

So he needs to fold around 50% of the time.

Re: Simple fold eq hand
 

Your math is fine. Basically you're losing 55 when he calls and win 52 when he folds. So you need him to fold 52/(55+52)=48% of the time.

But I don't really understand why you don't call in position and outplay him postflop when he 3bets this lightly.

I'm open to recommendations, but how are we gonna play 88 on different flops w/ a ~$90 pot?

Re: Simple fold eq hand
 

if theres any chance he folds JJ and AK you need to take that into consideration also.

Yeah, but I think it's probably just as likely he makes a hero call w/ TT than folds JJ.

Also I played around w/ pokerstove and gave him this 3-betting range (99+,ATs+,KQs,AJo+,KQo) which is 7.8% of hands, and with AK/AKs/JJ+ being around 3% this makes my push slightly +EV.
