(Assume NLHE cash game with 1/2 blind structure)
40 bb stacks not including blinds, SB open pushes top 50% of hands, find a calling range for BB that makes this a -EV push please.
Edit: I obv have no idea wtf im talking about (see chat transcripts)
That's nice, but give me the range and calculation to show that the range you gave makes my SB push -EV.Quote:

11:06:10 pm : spoonitnow : EV with BB folding = 1.125

12:25 am: 11:06:57 pm : spoonitnow : EV of SB losing SD = -5.63
11:07:18 pm : spoonitnow : Total EV = +0.025 bb
math is for ugly ppl, u should know that spoon<3
Spoon must be fucking hideousQuote:

Just to clarify. Do you mean 1/2 blinds with 80 chips in stacks or 1/2 blinds with 40 chips?Quote:

Anyway.
Ive assumed blinds of 0.5 and 1. BB means Big blind. If this isnt quite what you ment it should be fairly easy to modify it.
===============================
SB Pushes for 40BB
BB either calls and wins, calls and loses or folds.
Possibilities from SB perspective are:
BB calls, SB wins. +41.5 probability = A
BB calls, SB loses. -40 probability = B
BB folds. +1.5 probability = C
EV is 41.5A - 40B + 1.5C
with A + B + C =1 (since BB must either call or fold)
C = 1-A-B
so
EV = 41.5A - 40B +1.5(1-A-B) [sub in for C]
= 40A - 41.5B + 1.5
===========================
At this point I decided it would be more useful to put the equation in terms of the BBs calling range (R) and the Equity (E) we have when called by that range.
===========================
R = A + B => B =R - A
EV = 40A - 41.5(R - A) + 1.5
=40A - 41.5R + 41.5A +1.5
=81.5A - 41.5R + 1.5
A is the chance of being called AND winning so :
A = RE
where E is our equity against BBs range.
EV = 81.5RE - 41.5R + 1.5
======================
This is where I get stuck. There is obviously a relation between R and E but I have no idea what it is. My plan for when im really bored later is to plug some numbers into pokerstove and see where it takes me.
Ideally id be good at Excel and get it to make a graph with R and E as the axis, and colour code EV as RED = -EV, GREEN = +EV, BLACK = 0EV.
If anyone here is good at programming that shouldnt take too long. The other alternative is to plug numbers into pokerstove and see what happens. I tried a BB calling range of 25% and that came up pretty much neutral which suprised me. Someone take this off my hands plskthx.
