Yeah, I can do that. It's not appropriate though, because I'd base my calculations on very precise assumptions, and those are not 100% realistic. The result may be flawed, but only because the assumptions are, and most likely NOT the math. If so, pls correct (and teach) me.
The supposed betting range on 6th "4*, *c*c, $L$L, 22-AA / 4c 7s 7c 2s" is a bit wide. I'd take a few naked 4's and 224, 334, 554 without BDFD out of the range. Some bare FDs without a low draw on 6th, as well. [(T
9c
),...]. They might fold 3rd, might limp/call 3rd and often rather check/call or c/f 6th.
Widest Range 41%
Without 4's and 22-55 39%
Without *c*c is not much changed 38%
I'll go with 40% Equity for the whole pot.
EV for call 6th and call 7th (assuming he bets 7th as well):
We get 0,4*9.675BB-0,6*2=2,67BB longterm.
EV(Fold)=-5,675, EV(Call, Call)=2,67BB
At this point it gets a little fuzzy, because 7th will not 100% go check/check
a) he may check bare two pairs, missed FDs and some check/raises
b) we might improve to a flush/straight/trips/good 2pair and might value bet
c) we might get check/called by a better hand or check/raised by a much better hand
Are you okay with agreeing its almost always bet - call on both streets and the scenarios a)-c) does not really matter because we play them close to optimal and reevaluating will never make us fold 7th?
As
a) we have position (!!)
b) might bet/fold some thin value bets on 7th
c) check behind with SDValue almost always
d) if we do not raise 6th he will rather go for bet/raise with a boat then a check/raise
e) we do not loose much EV by not raising a flush on 7th (??)
+ calculated with a call on 7th already
we can add a little to the EV, so roughly we have an EV of 3BB.
Now to the more complex calculaitions with a few different „cases“
Assumptions about Villians Lines
I) Caps 6th with a boardlocked Low Hand
II) Bets 7th when he improves 7th to a low+ twopair
III) Check/Raises 7th with a boat
IV) Folds twopair when he faced a raise 6th and a bet 7th
V) BTW, probably never folds 6th
Hero’s line is raise/call 6th + either
A) Bet/Fold 7th unimproved (8s only) b/c of II)+III)+IV) to bluff out his twopair (Villian bet/calls 6th)
B) Call any 7th when got raised 6th, even the flush/straight/trip hands
C) If we get checked to 7th we can bet/fold almost any high hand for value that improved b/c of I)+ II)
At this stage we see again, our reads have to be precise and if they arent we are really screwed for so much EV, e.g. raising a semish Hand 6th, if get checked to 7th bet/fold good value hands against a lowboard. This kind of sucks, but we take these ideas for granted now and calculate as if they were 100% true, to show the EV the 6th raise might have in the best case. The mentioned reads and Heros 7th lines are the best case we can hope for.
Im still not pledging his 6th-move is genius, but I stated that under certain circumstances the EV might be not as bad as we think, and as I am scientifically ..shaped… there is a proof missing for my statement.
We need the probabilties of happening [P(A), P(B), P(C)] and the EV in that case.
A) He checks 7th, we bluff
We improve with every Xc, J, 5, T, 9, Q, 8. That are 7+3+3+2+3+3=16 cards. 13 cards known, make the probability of improving 41%.
In the case Villian bet/calls 6th, Hero bluffs 7th roughly 60%. The bluff works 100% of the time, unless he check/raises the boat (he is donking a made low 7th, remember II) )
If Villian bet/calls 7th he holds pair+LD only very very rarely. I mean he never bet/folds those b/c of the low potential, but as I clarified above, only crappy FDs have no twopair or no Low Hand made on 6th. With A24772 and such he has 3 Outs to the boat, with 754772 and such he has three 2, three 4s and two (5s, 3s, 8s) or three (4s, As, 6s). We assume he has [5, 3, 8] equally in is $L $L range as [4, A, 6].
Totalls up to either 10% to improve his twopair (Roughly samenumber of outs when holding A24772 as with (55-66,88-AA)4772, 21% to improve his trips.
We are assuming a lot, but trips are not much more likely than a twopair. Its realistic that he improves his high hand to boat 15%.
60% of all 7th street will be bluffed, <15% will be bet/folded.
Facts so far
1) We bluff 60% of all 7th street cards
2) 85% of our bluffs work, totally 51% of all runouts
3) We lose 1BB bluffing 9% of all 7th scenios
4) 40% of all 7th street cards we check behind
When we check behind all cards, we beat him with every improvement (41%) when he has the 2 paired and 10 cards (25%) when he has trips already/higher twopair. Sums up to around 33%, but reduces due to his check/raising boat range to 27,3%. This number would be much higher is we take teh crappy FD+LD hands in his range.
EV(A):
Pot is 9.675BB after 6th we compare the EV to a line that combines 6th and 7th.
60% of the time we bluff and win 9.675BB
85% it works = +9,675
15% it fails and we lose 3BB = -3BB
40% of the time we check behind
Win 27,3% of runouts =+2,64BB
Lose 72,7% of runouts =-7,03BB
=> EV(A)= 0,6*(0,85*9,675+0,15*-3)+0,4*(0,273*9,675+0,727*-7,03)=4,66BB-2,07BB=2,59BB
B) We get reraised 6th, and call 7th regardless of our down card
Villian raises high hands we are drawing dead against, and Low hands he is freerolling us with. Good point for not ever semibluffing 6th here.
Vs his Made Low Range we perform
Without 4's and 22-55 40%
Vs his Made High hands we are drawing dead.
Question here is, how his ranges are distributed. Hos often does he have a made high, when a made low when he raises? I have no was to determine this, but my experience tells me he has somewhere around 70-90% a made LOW rather than a made HIGH.
Pot would be 5,675+6BB+2BB=13,675BB
Our EQ on the total pot is 0,4*0,8+0*0,2=32%
=> EV(B)= 0,32*13,675BB-0,68*13,675=-4,92BB
C) We bet/fold all improvements for value and fold b/c only the best highhands are check/raising us
Thus bet/folding looks very fishy and we do this move on 6th also to influence his future play and to maybe to misaply this semishstyle in even worse scnearios, we want him to see our hand when we improved and we need to get thin value with our over represented hand, because underrepping is a way to be able to get thin value w/o fearing thin value raises/bluff raises much.
To simplify it and not go the easy route by saying we can ALWAYS fold to a raise, lets say we can mix up bet/folding and bet/calling dependign on our improvement and „feeling“ 50/50.
This calculation could be broken down to every improvement and could also be divided into cases, but if we improve with 40%, bet all improvements for value and bet/fold 50% of the time to his 15% boat improvement we would be getting
85% he calls UI
we win 2p>2p
we win flush/straight >2p,trips
we lose 2p<2p
we lose 2p<trips
15% he check/raises
we fold randomly/improv dep. 50%
we call randomly/improv dep. 50%
With some thoughts and combinatorics we will find E(C).
————————————————————————————————————————————— —
Next step would be to fill the gaps in this equation, which sums up the question.
Is P(A)*2,59BB+P(B)*(-4,92)+P(C)*E(C)>2,67BB given?
If you agree that’s what we are looking for and you want to see the proof that its more close than we might thought, I will elaborate.
The Nash/GTO thing would be the next step I’d take when I got formulars depending on his line-mixups and I try to perfectly balance this and think about it more outside the box, not vacuum-wise and based on 100% must-be assumptions.
EDIT: The "%-trees" are supposed to be visualized by indention, apparently boards dont copy them from my text editing.
