Run it once or twice
I did a quick search of this forum and didn't find anything relating to this. I play in a home game where when anyone is all in each player is asked whether they want to run it once or twice after the flop. If both players agree on running it twice then it is ran twice, if one player says run it twice and the other says run it once, then it is only run once.
In what situations is running it twice profitable or when once is profitable. As I understand it running it twice reduces variance so say you call someone with just a flush draw do you want to run it once or do you want to run it twice. Any help would be appreciated. |

Re: Run it once or twice
The EV never changes, only the variance.

Yeah. In the 'long run' you always experience regression to the mean. Running it twice just reduces the swings. |

Re: Run it once or twice
There is no difference in EV over the long run... but there are other reasons why you may want to run it only once.
Barry Greenstein said that he never runs it more than once for psychological reasons: (1) people will be more scared to move in on him. If he runs it more than once, players may feel that they have some 'insurance' and will get (on average) a portion of their money back. These players might push all in with a draw more often if they feel they will win a portion back by running it multiple times. (2) giving another player a bad beat in a big pot may tilt them. Just make sure that it won't tilt you if you lose a big pot by not running it multiple times. |

EZ
run it once if favorite, twice if not favorite. also, running it twice against a bad player whom is a huge donator isnt a bad thing b/c it keeps him happy. holla |

Re: Run it once or twice
What happens if the results are different? Its a no bet, and move on to the next hand?
"Run it once if you can stand the variance, twice if you can't." This sounds right, and I think if you extend it to tournaments (if there is such a thing as a "run it twice" tournament) that running twice might change tournament EV. As DS demonstrates in the tourney book, when losing a +EV bet precludes you from making a more valuable bet later on, passing on the first bet may be >EV. This applies to tourney situations where you might pass on a small edge all-in, since there may be more favorable situations later. However if you can "run it twice" and therefore have (1-(1-p)^2) probability of surviving, instead of just p, that may improve your tourney EV. |

If you win once, you get half the pot, if you win twice you get the whole pot. If you want to make poker a sport, as opposed to a game, it would make sense in tournaments to award according to the mathematical odds at each all-in situation (that's sort of like running infinity times). That would reduce the amount of luck, and make it more likely that the most skillful player wins. Personally, I don't want to make poker a sport, and I decline to run it twice, except rarely and to please someone else. |

Re: Run it once or twice
Supposing you think you have an edge, you should do it if the other guy will have no other way of rebuying, or you have no more cash on hand.
DUCY? |

Re: Run it once or twice
its neither profitable for those behind or ahead... it just reduces variance
