2 Book Ideas

[Roadstar]

Alright, here is another "help me decide what book to buy next" post.

Background - I started playing online poker a year ago, almost exclusively limit poker, started from .5/1 and worked my way up to 2/4. I'm looking to expand my game a bit to no limit holdem, and probably cash games since its much more flexible that tournaments since I can play and leave whenever I like.

Books I already have/read - Lee Jones on Limit, HFAP, SSHE, Super System, Mike Caro's Poker tells, Theory of Poker, HoH 1 & 2, Internet Texas Holdem (the Kilger or Hilger book).

I'm thinking of getting a good book for NL cash games (which I think not many exist when I searched the forum) and maybe a book to help me move up to the 5/10 - 10/20 level in limit.

Any suggestions?

How good are the Caffione books - The Middle Limit book and the pot and no limit books?

How about King Yao's?

Thanks guys!
