Poker book question.

I was thinking of buying a few instructional holdem books. I am mainly interested in online strategy books. Any must haves that you guys have read?
Thanks in advance!

There are a lot of threads about this topic already, might be better just doing a forum search for them.

A lot of depends on whether you're looking for cash game (ie deep stack) books or tournament books. For deep stack read Super System II, Negreanu's Power System (avoid his others) and Harrington's cash game books. For tournament play read Harrington's tourney books and Cloutier's books, especially his How To Win the Championship final table book.

Ill do some forum searching, thanks alot for the input though.

Here's some poker book reviews that may interest you:

A lot of people have read the Brunson and Hellmuth books, and while they are good reads I've found that the best education you can recieve is at the tables, if you are losing there is probably a reason, and if you can figure out why it is over time you will develop a more well rounded game then any book could ever give you.

I have read several of John Vorhaus books.He is not as big of name as the others,but he has an awesome insight into poker from alot of prospectives.Give him a read and I dont think you will be dissapointed.
