If DS & Ed wanted to be useful, they might explain WHY think think it's 60% likely their opponent will fold to a given bet, rather than assuming such a critical and hard to get piece of information and then showing us some arithmetic anyone who did well in 4th grade could set up and do on their own.

I have to agree. From that perspective, the book is practically worthless.

Here's a contrived example. Let's say you are bluffing, and can get your opponent to fold TPTK 80% of the time with an all-in bet of 4 times the pot size, 60% of the time with a bet the size of the pot, and 10% of the time with a bet half the size of the pot.

Well, then they show the high school math, like

(.6)(100)-(.4)(100) > (.8)(100)-(.2)(40)) > (.1)(100)-(.9)(50)

and say something like "Some players believe if you bluff, you should pick the amount that gets your opponent to fold the most often. But as you can see, you should make the play that maximizes your expectation, not the play that gets him to fold most often." (As if that's earth shattering.)

So basically we've just wasted 15 minutes reading a section that tells us "maximize your expectation", but doesn't tell us how to play poker.

As you can see, while it's called "Theory and Practice", there's very little "practice" involved. And sometimes the "theory" ain't exactly the shiznit either.
