what I mean by permutation "levels" is this:

anyone can pretty much figure out what their odds are of catching the flush on the river, or of filling your two pair..

but when you add in implied odds, expected odds, add up the percentage chance you think he's bluffing to the outs you think he has (HOH),then the thinking starts to hurt my head.

I'll try another search, and if that fails, Im just gonna pull out a paper and pencil and do the problems till they become easy.
