This
article by Clonie Gowen discuss a simple way of approximating your odds of making your hand based on your outs.
Using her method on a hand like a flush draw.
After Flop = (9 Outs)*(2 Cards to go)*2= Approx 36% chance of making your hand.
After Turn = (9 Outs)*(1 Cards to go)*2= Approx 18% chance of making your hand.
This method seems much easier to compute on the fly than the method explained in Dan Harrington's book, which is:
After Flop and Turn = (37 non-outs) to (9 Outs) = Approx 4 to 1, which is Approx 25%
My question is who's method is better. According to Clonie's way of figuring odds I would call a 4 to 1 pot odds with a flush draw post flop without any hesitation. However, I would fold to 4 to 1 pot odds after the turn without much thinking. But using Dan's method I would agonize on both calls but I would probably still have call due to the implied odds.
Just as a sidenote, you could apply Clonie's simple method to pretty much get Dan's figures by using this formula:
After Flop and Turn = (9 Outs)*2+(9 Outs)= Approx 27% chance of making your hand.
I am just curious what everyone' opinion on this is.
