What's the best book for 6-max NL 2/4 and higher with 100bb max buyin?

[Albert Moulton]

I play live 5/5 NL max 1000 buy-in. A lot of the 2+2 books have theories and tactics that make sense in that game.

But I hang out a lot on the Medium Stakes NL forum where most posters are playing 100bb 6-max games at stakes of 2/4 to 5/10 or so. In those games, 3-betting light OOP, stacking off with overpairs, and playing KTo like its AK at a full ring game not only seem to be the norm, but appear to be +EV.

So, what book, if any, can explain how these guys think, and why their style in these medium stack, short-handed games is +EV?

I'm not particularly interested in playing in that game, but I would like to understand a little better why the way they play works so well for them. In the game I play, I'm pretty sure I'd be broke with a lot of the lines they take profitably in that game.
