Quick odds question TD.
I get dealt 86532. With no knowledge of other cards, how often will 27xxx catch up to make a seven by the river?
What about 237? around 40%? |

[/ QUOTE ] I ran 27AQJ through my draw results tool (with 86532 as dead cards); it says there is about 16% chance of making a 7. (There is only a 12% chance if villian will screw up and keep an 8.) [ QUOTE ] What about 237? around 40%? [/ QUOTE ] About 23%. I tried working this one out by hand using permutations, but I came out with a different answer and realized I'd double-counted. And I'm too lazy to go back and fix my math. |
Re: Quick odds question TD.
15.87% for the first question, a friend of mine constructed a rough monte carlo simulation, so the 16% is gooooooood./
btw Mark what do you use to calculate that ? |

[/ QUOTE ] A software tool I wrote myself. It calculates the end result of a draw given some simple constraints (drawing to 7, 8, or a 9). There are some tricks I use to make calculating the exact probability work in a short amount of time (without using monte carlo techniques) but the code doesn't handle potential flushes well at the moment. I'm working on a version which will calculate hot+cold EV for perfect play (i.e., no betting in later streets, always drawing with knowledge of other players' cards) but I haven't made much progress lately. |
Re: Quick odds question TD.
that sounds great, my friend wrote some bunch of code in VBA / Excel, it seems robust but not very good in terms of calculus performance, it took 10 minutes to makes 200,000 monte carlo simulations on this hand [img]/images/graemlins/frown.gif[/img]
at least it gives me quite the same results you have [img]/images/graemlins/smile.gif[/img] |
