97o getting a staight
what are the odds of 97o, all in preflop, getting a straight coming in at the river? Or just getting a straight at all?
I went all in on a guy in a small dfriendly tourny, We were the last two players in. I had 99, he shows 97. He takes home the money with a straight. |

Re: 97o getting a staight
You need to be more specific. Does the board coming A-K-Q-J-10 count? What about 3-4-5-6-X? Are you asking about using both cards?
Are you really just looking for the odds that you'll win this hand? |

Re: 97o getting a staight
I should have been more specific. I meant making a staright with just the 7.
the chances of winning i think are 80+%. ya.cool.thanks. |

Re: 97o getting a staight
Well, with just the 7 you're looking at a board of 3-4-5-6-X where X isn't an 8 or a 7.
=(4 * 4 * 4 * 4 * 39)/COMBIN(50,5) = 0.471219% Note: This includes flushes/straight flushes. |

Re: 97o getting a staight
LetYouDown,
Where did you get this 39 number? If we assume that two nines are not taken out, then it has to be 52-4(sevens)-4(eights)-2(9,7) = 42 cards for X. So, for no 99 case it will be: 4^4*42/C(50,5)= 0.507%. With 99 exposed: 4^4*40/C(48,5)= 0.598%. Am I right here? |

Re: 97o getting a staight
52-4(99 and 97)-4(3,4,5,6)-4(4 eights)-3(3 remaining sevens)=37 is what I get.

Re: 97o getting a staight
KJL,
You are wrong here - we don't mind having more than one card from 3-6 rank range (they will not ruin the hand). |

Re: 97o getting a staight
Yes, but in order to make the staright we need to use one 3, one 4, one 5, and one 6 for a total of four cards.

Re: 97o getting a staight
oops, a couple of corrections:
1. Three sevens left in the deck, not four (my fault) 2. We are actually not afraid of eights here 3. 4568x(no seven) is winning too, so it is getting a little more complicated. Ok, let's try again: 52-4(99, 97)-3(777)-4(four cards already picked out)= 41 and the chances to win are: 4*4*4*8*41/C(48,2)= 1.22% |
