Why are you 95% sure of a flush? [/ QUOTE ] It's just an estimate. It's very hard to come up with many situations where netiher player has a diamond in his hand. [ QUOTE ] How low would the chance of somebody holding a [img]/images/graemlins/diamond.gif[/img] have to be for bet-fold to be the correct line? [/ QUOTE ] If you understand the EV calculations, you should be able to work this out. It's a good exercise if you haven't done many of these. (It's actually quite easy.) |

My first posted EV calculation...
The Bet-Fold Threshold: EV = 0 = x * (-1) + (1-x) * (6.25) x = 86.2% One would have to be less than 86.2% sure that one of the two opponents has a diamond to bet-fold the turn. I think that makes it pretty close, no? |

[ QUOTE ] I don't mind the turn check, you aren't getting anyone to fold that's ahead of you. I doubt you are good 1 time in 8 on the river. [/ QUOTE ] I disagree. I think the b/f line is much better on the turn. Here's why - basically, on a 3 flush flop, villain will lead out with many non-flush or non-FD made hands like 2 pair or TP or a flopped str8 - he even sometimes bets out with his flopped OESD. A flop of 9TJ will hit a ton of hands that someone limps with UTG. Basically, the line is b/f because there's such a good chance the other two are not liking the diamonds too much and you may even get a better hand to fold. And it's a pretty easy muck when you get c/r. And to the poster who thinks BB is obviously on the Nut flush draw after calling two cold: He is the BB. He did call a raise PF but that doesn't mean he did it with the Ad or even the Kd or Qd. [/ QUOTE ] On this flop, what did the BB call 2 cold with? |

The 10% is deceptive if you don't think of it in light of being relative to a number on the order of 5%. There's an old gem about this sort of thing: Ed Miller would just love this one: KK in MP. Ironically, it's about folding an overpair. I've linked it directly to a post by GuyOnTilt, but it's worth reading the thread, too. |

Why are you 95% sure of a flush? An earlier poster noted that the flop action could be due to strong(ish) non-flush-draw holdings trying to protect their hands. How low would the chance of somebody holding a [img]/images/graemlins/diamond.gif[/img] have to be for bet-fold to be the correct line? [/ QUOTE ] I think 95% is spot on. I think of it this way: 2 villians w/ 4 cards the chance of one of those cards being a [img]/images/graemlins/diamond.gif[/img] is 100% on average. I am just learning the math associated with this stuff so bear with me here. I am correct in thinking that in order for the call on the river to be +EV there has to be a least 21BB in the pot, AND we have to damn sure that the 5% of the time they don't have a [img]/images/graemlins/diamond.gif[/img] that our HIG? |

I am just learning the math associated with this stuff so bear with me here. [/ QUOTE ] That's not true. Given four random cards out of a full deck, the most common number of diamonds is 1. This is much difference from saying there is one out there 100% of the time on average. (Think of it this way: The average sits between other values. Can you have a diamond out there 110% of the time?) What information do you have? You know that there are 4 diamonds on the board and I don't have one, so there are 9 left in the deck. You also know that there are 2 non-diamonds out (in my hand) so that there are 37 non-diamonds left. The probability of there being some diamond in someone's hand is 1 minus the probability of there being no diamonds out. (37/46)*(36/45)*(35/44)*(34/43) = 40.5% So there's a 59.5% chance that someone has a diamond if you only know what cards are out there. But we know more. We know that there was a flop donk and coldcaller. That makes this number unreliable because the calculation doesn't take the action into account. |

I'm glad I posted. I was all wrapped around the axle and you set me straight.
Thanks Aaron! |

[/ QUOTE ] Actually, I don't think we have to be good if neither opp. has a [img]/images/graemlins/diamond.gif[/img]. In fact, I don't think we have to beat anything if nobody has a flush, because both opponents will almost surely fold. Aaron- does the possibility that a low [img]/images/graemlins/diamond.gif[/img] flush will fold on the turn move the numbers around in any significant manner? Also, thanks for clarifying the difference between 95% and 86%. I still am a little unclear as to why being 95% sure of something is very different than being 86% sure, but I haven't read that thread yet. |
