When it comes to books about poker strategy, we tend to think of them being written for a particular audience — namely, poker players enthusiastic about the game and eager to learn how to win more often.
We also tend to think of the authors of such books as being primarily interested in teaching readers how to play the game more skillfully. Indeed, that may be the only purpose we would typically attribute to poker strategy writers — to provide instruction to help readers play better poker.
That said, when looking back through some of the earliest poker strategy texts, we discover many authors not simply satisfied with telling readers how to play poker.
