How to calculate odds?????

[craigbeez]

Can someone explain to me in detail how to calculate the odds after the flop, turn, river?

Thank you in advance,
Craig

First you go to Borders.
Then you buy Winning Low Limit Poker by Lee Jones or Hold'em Poker by David Sklansky.

Finally, read the books. /images/graemlins/tongue.gif

Thanks for nothing, if I wanted the answer from a book I would have went to the bookstore. /images/graemlins/confused.gif /images/graemlins/mad.gif

With one card to come, it's quite easy to figure out the odds. Let's say you have x outs (cards that complete your hand), and there are y unknown cards, then the odds agains you making you hand are y-x:x. For a flushdraw on the turn in hold'em, x=9, y=46 so the odds are 46-9:9 against, or 4.11:1 against.

With two cards to come it's a bit more complicated. I usually use this formula: 1 - (y-x)/y * (y-x-1)/(y-1). For a flushdraw in holdem, from the flop, this gives:
1-37/47*36/46=35%. You can convert the percentage to odds like this: (100-35)/35=1.86. That means the odds are approximately 1.86:1 against you making your flush if you see both the turn and the river.
