No Limit Hold'em Theory and Practice - by David Sklansky
Grade "A+"
Hands down the best book ever written about NL hold'em with an emphasis on cash game. A real bargain at less than $20.
Super System 2 - by Doyle Brunson
Grade "A-"
A great book that covers everything from NL Hold'em to 7 card stud. With tons of "guest writers" this really is an excellent book.
