BB: $41.15
CO: $55.05
Pre Flop: ($0.35) Hero is BTN with 4 7
1 fold, Hero raises to $0.75, 1 fold, BB raises to $1.75, Hero calls $1
Flop: ($3.60) 4 T 6 (2 players)
BB bets $3.50, Hero calls $3.50
this was a weird bet by villain, i wouldnt expect villain to bet this big with a huge hand here. i think its mainly trying to buy the pot with whatever he 3betted pre flop. even if he does have like AA i still have equity with my 5 outs to make trips/ 2pair. i basically decide to see what he does on the turn.
Turn: ($10.60) K (2 players)
BB bets $5, Hero raises to $19.85 all in, BB calls $14.85
when he bets so small on the turn i cant see him having a huge hand at all. it seems more likely that the king scared him than helped him, and he is just betting to 'see where he is at' or whatever random reasoning he has for his smaller than half pot bet.
i dont like his sizing if he does have AK/ AA type hand, because his shove sizing on the river will be 3/4ths pot, and i will be able to easily get away if i held a hand like JJ/ 9T for example.
using a bit of maths on pokerstove, i basicaly have 30% against a range of AK, KK, AA, and AQcc. i dont think he calls with any other hands (i eliminate 66 and TT from his range because i dont think he ever has those based on his actions), so using fold equity and my equity when called, i only need him to fold 23% of the time to show a profit. i think he is bet/folding this turn at least 1 time in 4, so therefore this is profitable.
River: ($50.30) 8 (2 players - 1 is all in)
he actually had AK which is of course a standard call by him, i still had 31% on the river, but unfortunately didnt hit, though its important to note that i dont expect him to call very often and am essentially trying to maximise my fold equity whereby i only need him to fold 1 time in 4
Ok so I'm trying to learn fold equity and for practice i did the math to get the fold equity you came up with. I'm just going to post the formulas as well as do the math.

The base formula to get fold equity when EV is 0:
EV(total) = [EV(fold)]*x + [EV(call)]*(1-x)
EV(fold) is what we get when the villain folds, which is pot + his bet
EV(fold) = $10.60 + $5.00 = +$15.60
EV(call) is total pot * our equity vs his range - our bet
EV(call) = ($50.30) * .3 - $19.85
EV(call) = 15.90 - 19.85 = -$4.75
EV(fold) = +$15.60
EV(call) = -$4.75
Break Even Fold Equity ( Same as above ):
EV(total) = [EV(fold)]*x + [EV(call)]*(1-x)
x = % of times he needs to fold so that we break even so we solve for X
0 = 15.6x - 4.75 + 4.75x
0 = 20.35x - 4.75
4.75 = 20.35x
4.75/20.35 = x
22.1% = x
when op said he just needed 23% fold equity to be profitable we still need to consider if villain will actually fold enough of the time. So we have to look at hand combinations he will continue with and what he wont.
Total 38 combination of hands:
KK = 3
AA = 6
JJ = 6
AK = 16
AcQc = 1
JTs (suited and none club) = 3
T9s (suited and none club) = 3
Total = 38
Hand combos you assume he would fold:
JJ, JT, T9 = 9
Hand combos hes calling us with
38 - 9 = 29
% of hands hes calling us with
29/38 = 76%
% of hands hes folding against us ( our fold equity in this spot )
24%
so we plug in our fold equity in this spot into the break even ev formula i listed earlier so we find out actually ev for the play.
EV(total) = [EV(fold)]*x + [EV(call)]*(1-x)
EV(total) = (15.6*.24) - 4.75 + (4.75*.24)
EV(total) = 3.74 - 4.75 + 1.14
EV(total) = +$0.13
So every time we make this play we are risking $19.85 and our expected value is pretty much break even. which makes this a high variance play. If just one read is off and our hand combo assumptions are changed then we go into the minus ev pretty easily
Anyone knowledgeable on this stuff please check my work :P
EDIT: *FIXED SOME ERRORS WITH THE HAND COMBO PART*
