SB: $19.56 (391.2 bb) {47/23, 7/36 (19.4%) 3b, no reads on how he plays to 4b, 42% fold to CB, 93 hands
BB: $14.23 (284.6 bb)
Hero (MP): $5.22 (104.4 bb)
CO: $11.51 (230.2 bb)
BTN: $4.91 (98.2 bb) {48/17, 23 hands}

Preflop: Hero is MP with A K
Hero raises to $0.20, CO folds, BTN calls $0.20, SB raises to $0.80, BB folds, Hero raises to $2.20, BTN folds, SB calls $1.40

Flop: ($4.70) 3 6 T (2 players)
SB checks, Hero bets $3.01 and is all-in ??

Okay so I've broken down opp's range as such:

CALL 4B: 93 99+,A9s+,KQs,ATo+,74o
CALL: 48 QQ-99,AQs+,AKo,74o
RAISE: 6 KK+
FLOP CALL: 29 QQ-99,AKs,7h4d,7s4d,7s4h,7c4d,7c4h,7c4s

I added the combos of 74o in there just to account for any trash he will likely show up with from time to time. Based on this, I've calculated our eV to be +$2.13. However when I moved opp's folding freq to 0, I found we still had a +eV bet:



I don't understand why we still have a +eV bet even when we have no fold equity here? I would expect it to be hugely -eV! Is my formula off? I don't think so:

=(B4*B1)+(D4*B5*(B1+B2))+(D4*D5*(-B2))

But anyways my main question in this hand is is jamming our best option here? I think we get bet into a fair bit OTT by his range when we check the flop and we just have to fold... or is 4b pre a bad option considering he's only stacking off KK+?

...thoughts?
