ハンドをプレーする

$0.1/$0.25 No-Limit Hold'em (6 handed)

Known players:
[tg]BU$25.97:///////;SB (Hero)$28.32:///////;BB$86.45:///////;MP2$33.88:///////;MP3$27.27:///////;CO$25.00:///////;[/tg]

Preflop: Hero is SB with 8:h, 6:h.
3 folds, BU raises to $0.85, Hero raises to $2.50, BB folds, BU calls $1.65.

Flop: ($5.25) 7:d, 2:s, K:c (2 players)
Hero bets $2.75, BU calls $2.75.

Turn: ($10.75) 5:d (2 players)
Hero bets $5.50, BU calls $5.50.

River: ($21.75) 5:c (2 players)
Hero checks, BU checks.

Final Pot: $21.75.

Results follow:

Hero shows a pair of fives(8h 6h).
BU shows two pairs, kings and fives(Qc Ks).

BU wins with two pairs, kings and fives(Qc Ks).

he is unknown .
if he folds 88-TT on the turn,I thought its profitable to semibluff .
do average players would fold to this bet size with those hands?

and want to know how to calculate break even fold equity on the turn,
equity of OESD is16% ,and lets say he folds all hands other than Kx and Kx would call to all in on the river .
risk :5.5 but if get called ,I can win 16%
so 21.75*0.16=3.48 would come back
5.5-3.48=2.02
gain 10.75+15.22(profit of River)=25.99

so 100*2/28(2+26)=7%
if he folds more than 7% ,its + EV,right?

Hey Daisuke,

Line looks fine. X/f flop also not unreasonable here.

Agreed that our expectation when called is 3.48. Hence if we assume we have very little fold equity with our flop bluff our losses must not exceed 3.48 otherwise we fail to break-even. Hence - (where P is not part of the equation - it just means probability of)

P (bluff-success * amount won) - P (bluff-failure - amount lost) = -3.48

P(F * $10.75) - P((1-F) * $5.50) = -3.48

And from here it's just algebra

10.75F - (5.50 - 5.50F) = -3.48

10.75F - 5.50 + 5.50F + 3.48 = 0

15.25F = 2.02

F = 2.02/15.25 = 0.13 or 13% FE

Why 3bet SB vs BTN vs unknown 3,5bb Steal with 86s? I think it will be never good preflop.

Yeah, tbh I was mainly focusing on the EV calc since that seemed to be the main question here.

But you are right, it's too wide vs 3.5bb BTN open from unknown.
