This push plus or minus EV
Hi All,
I am interested in calculating the EV for this. I posted this to the 1 table tourney forum earlier. I received some helpful comments but alas I still can't figure out how to do it. Any help is appreciated. 1 table live home game SNG tourney Buy In $30 Blinds T150 / T300 Stack sizes (before posting blinds) BB 1100 SB 2000 Button 2500 I'm in the BB with 56 offsuit Folded to the Button who calls SB completes Pot Size now T900 I raise All In from the BB for an additional T800 Let's assume the following: 1. Button calls BB with top 50% of hands 2. SB completes with any two 1. Button calls All In with top 25% of hands 2. SB call All In with top 25% of hands |

Re: This push plus or minus EV
This question is underspecified.
To compare pushing with checking, you need to make some assumptions about the postflop play. If you push and are called in two places, will the players check it down? If you check, what will happen postflop? Also, you said that the SB would call with the top 25%. Is that only if the button folds, or does the SB not care? I'll assume the SB doesn't care. I'll use folding as a baseline. If you push, about 3/8 of the time, you pick up the pot, gaining 900. About 1/2 of the time, 1 player calls. You have put an extra 800 into a pot of 2500, and you expect to get back about 33.4%, according to PokerStove, 835, for a gain of 35. About 1/8 of the time, both players call, and I'll assume they check it down. You have put an extra 800 into a pot of 3300, and you expect to get back about 24.7%, 815, for a gain of 15. The average is a gain of about 357 chips compared with folding. If you check, you have a weak hand and a positional disadvantage, so you shouldn't expect to get 1/3 of the pot, 300. Pushing should average more chips |

Re: This push plus or minus EV
Hi,
Thank you for your effort. [img]/images/graemlins/smile.gif[/img] I will try to be more specific: 1. Let's assume that the SB will only call my All In with top 25% and that he doesn't care what the button does. 2. Let's assume that if I push and am called in both places, both players end up seeing the showdown. 3. If I check, well I'm not quite sure. What makes sense here? Can you assist me in understanding the methodoloy you used? This will help me to perform these calculations myself in the future. Regards, jenson “Give a man a fish; you have fed him for today.

Can you assist me in understanding the methodoloy you used? [/ QUOTE ] I'm not sure what methodology you mean. To get the pot equity when called, I used PokerStove. Incidentally, I used the slider in PokerStove to choose the top 25.2% of hands. That might not be the right set of hands for overcalling. To get the figures like a 1/2 chance that one player calls, that came from considering the 4 possibilities of whether each player would call. There was a 1/2 chance that the button would call, and I assumed that independently, there was a 1/4 chance that the SB would call. So, there was a 1/8 chance that only the SB would call, and a 3/8 chance that only the button would call. |

If you push, about 3/8 of the time, you pick up the pot, gaining 900. [/ QUOTE ] I'm a little confused regarding the above quote. If there is a 1/2 chance that the Button calls and a 1/4 chance that the SB calls then isn't there a 3/4 chance (1/2 + 1/4) that at least one of them calls? Again, just trying to understand this so that I can use it in the future. Thanks for the clarification. It is much appreciated. Regards, jenson |

Re: This push plus or minus EV
Too late to edit my previous post but on further consideration:
If there is a 1/2 chance that the Button calls and a 1/4 chance that the SB calls and a 1/8 chance that they both call then isn't there a 7/8 chance (1/2 + 1/4 + 1/8) that at least one of them calls? Otherwise put 1/8 chance that they both fold. Now i'm really confused. [img]/images/graemlins/confused.gif[/img] |
