You can find many titles on the Internet. However, you cannot have prejudices about them. Everyone wants to sell their book and will only talk about it in superlatives. I prefer to receive recommendations from the living people I'm in contact with on the forum. I would also prefer newer books, although I will not despise the classics. For now, I've read two books by Jonathan Little. Bluffs and Excelling. The third is The Poker Mind Set.
I'm looking for books especially for cash games texas holdem no limit. But I'd love to read a book dedicated to tournaments. But I'm totally green here! I want to learn new things. But I don't want to learn about GTOs yet. I guess you don't need it on the micro. Right?
