Math!
I really need to learn the basic math stuff once and for all, and I think this hand is pretty good for the basic stuff. I have three questions that I'll add after the hand.
NL 6-max Random preflop action. Flop comes T92. I have QQ. Pot contains $49 after my opponent bets. I have $89 and my opponent covers. Let's put my opponent on AK, AA-JJ. He will never fold to a push on the flop. Combos: AK (16) AA (6) KK (6) JJ (6) total (34) Percentage that he has a certain combo: AK ~47 % AA ~18 % KK ~18 % JJ ~18 % Question 1: How do we calculate if a push is more +EV than folding? Do we set folding at zero EV, or do we set it -x since we have equity in the pot? I have this vague memory of using folding as zero EV. If I push and he has AA, my equity is ~13 %. Do I just take the full pot size, $227, and multiply it with 0.13 to get my equity, in this case $227*0.13 = ~$30? Comparing this number to folding can't be right since folding had zero EV, meaning that my push is making me money, which I'm pretty sure it doesn't. I therefore assume that we have to compare it to my stack before I push, which shows that it is a -EV move. This means that the simple way to do this is to just compare out expected stack size if we push to our current stack size to see whether a play is profitable or not? But if that's true, aren't we using our stack size as "zero EV (whatever it is called)"? Question 2: How do we calculate our EV if we push vs his range? Question 3: How do we calculate our EV if we push and he folds JJ 10 % of the time? |

Re: Math!
After you learn how, you can use Poker Stove to do your math.

[/ QUOTE ] Thanks for the tip, but Poker Stove won't really do the trick since you can assign probabilites to holdings and how often each of them will fold. What if I would like to use 20 % folding equity when he has JJ and 95 % when he has AKo, combined with 0 % folding equity when he has AA and KK. How do I put all of that into PS? |

Re: Math!
I guess you will have to use excel. I use Excel to do my EV stuff when I have multiple probability branches I want to balance. Sorry, I thought from reading your original post you wanted to be able to figure out the advantage of different ranges of holdings vs yours.

Re: Math!
Qu1: Folding is 0 EV. How the money went into that pot is of no interest any more. So if You fold, You loose nothing and You win nothing.
Qu2: Let n be the number of hands in his range , pc[1]...pc[n] be the percentage for any combo of his range and let wc[1]...wc[n] be the percentage You win against this combo. You need a poker calculator to determine that percentage for every hand. Given these percentages, this is the calculation: (1) (pc[1]*wc[1] + ... + pc[n]*wc[n])*$138 (2) (pc[1]*(1-wc[1]) + ... + pc[n]*(1-wc[n]))*$89. Your EV is equal to (1)-(2). So, if (1)-(2) is positive, You have to push, if it is negative, You have to fold. Be aware of the amount of the money in the equations: You gain the pot size + an additional $89 if You win, because You assume that Your opponent never folds, and You loose only $89 if You loose. The money already beeing in the pot is not part of Your loss. Qu3: The equation will be more complex now, but all I told You about the EV after You calculate Your equation remains the same: Let JJ be hand n: (1) (pc[1]*wc[1] + ... + pc(n-1]*wc[n-1] + pc[n]*wc[n]*0.9)*$138 + 0.1*$49 (2) (pc[1]*(1-wc[1]) + ... + pc[n-1]*(1-wc[n-1]) + pc[n]*(1-wc[n]*0.9)*$89. The amount of 0.1*$49 in (1) represents Your fold equity. |

Thanks eigenvalue. With your post, as well as fimbul's, I'm sure I'll be able to do my calculations. =)
