Do you have any examples? I have never seen one that is very obviously wrong.

I while, it is true that we profit from our opponents mistakes, and our opponents profit from ours - I believe his definition of "mistake" is flawed, or at least not the best judge of proper play.

Nevermind, I have my copy at work. Expect a follow-up!

Ok, he talks about the "mistakes" too.....

His example is pretty vague at the end of the chapter, and shows how you may profit by a correct raise and fold by your oppenets but it is not specifc and I am having a hard time constructing an actual situation.
