I know there has been some discussion about King Yao's DIPO system for analyzing pot odds. I think that the general consensus was that it was either too hard or unnecessary.

I have just read the section that describes DIPO and I like it a whole lot more than just counting your outs and comparing it to the pot odds. The reason is that DIPO naturally takes into account the implied odds by assessing the expected pot size. I think that this makes it more accurate for the turn than using the outs vs pot odds method.

I think that this method is more straight forward for someone who has not memorized the relationship of # outs to pot odds. However I can see how many who already use pot odds would feel that DIPO is more complicated since they are used to the former.

Congrats on a great book Yao.

DIPO is a good concept, but there's a simpler way and it was outlined by Abdul in his Theory of Sucking out. In fact, Yao credits Abdul in WTO. (And Abdul credits the late Andy Morton for the multiplication trick in the Theory of Sucking Out):

Reduce expected pot size (including future bets won) to an expression of X:1. Take X, add 1, then multiply by your effective outs. If that number is greater than 47 on the flop, or 46 on the turn (i.e. unseen cards), then you can call.

Example, you are getting 8:1 on the flop with a gutshot to the nuts on unpaired, rainbow board against 2 foes. You figure if you hit the turn, you collect 2 big bets on the later rounds. 8+2+2 = 12:1. 12+1 = 13*4 outs = 52 > 47 unseen cards so call.

Or you can shortcut it like I do in implied odds situations. I take the actual pot odds, add 1, multiply by effective outs and compare to 35 on the flop and 40 on the turn as a shortcut to figuring implied odds. It's not exact, but it's fast and accurate enough.
