The maths?

jonjo75

In the late stages of the 12k BH and I went out to this hand.
Straight after the hand I was trying to work out the maths in my head and came up with him being a  very slight favourite after the flop but after running it on a poker odds calculator it said I was 60% fav.
I know I have one of his outs ( the 6 diamonds)  but that still gives him 14 outs.
Can anyone explain the maths to me?
Thanks.

9 x Diamonds left.  4 x 4's & 4 x 9's?

edit: actually mite be 15 as 4d & 9d are duplicated?

Yeah you are counting the 9d and the 4d twice and the 6d would give me a house.
so its 8 diamonds , 3 x4s and 3 x9s =14

You are correct of course.  14 it is!

Yeah, your odds of winning the hand are higher than you think because even if he hits his flush, you have full house draws.

he has 15 outs to make a flush or straight - he will do this roughly 60% of the time.

However you will improve to a full house or quads roughly one third of these times - thats why he has roughly 40% equity

Hi J

Yea unfortunately when you consider outs then that is to find the chance of improving NOT winning the hand outright. For instance if you improve then the probability of your opponent improving and beating your even improved hand. Also equity includes split pot probabilities not outright win probabilities. There is a calculation that can be made but may be a bit complicated for here. As an ex maths teacher, i've had too many students fall asleep showing this stuff so you're better off sticking to pokerstove.

In short, start with hand thats ahead...you.
Now consider other hand...how many outs to improve his hand?....9+runner runner 5/7 no order as two pair will take pot too. (You can only make a rough calcs for these outs!)
If he gets J diamonds on turn say to improve then you can win by pairing board for full house or catch remaining J for quads (yippee!!) so you can see there are permutations of hands involved in this calc.

Rules of 4 and 2 are just approximations in order to tell you if you are making a good bet by considering the pot odds in comparison (a lot get around it by say "i had implied odds!).
Hope this helps some......there are ways to self calc it all but they tend to be approximations. as ong as you can see where and why the differences come there's no real need when you only have a ten second clock as there "ain't no time!!' to do it.

Hope this helps m8

Thanks this makes a lot of sense. I knew it was because if the board paired I would win but just couldnt work out the 60/40 split.
