I don't think either are "cons". The authors don't put a gun to your head or charm you to buy books; you make that decision when you're reading an online sample chapter, review, or looking at in a book store.

FWIW, I have a few mediocre at best poker books that I've bought and read. I follow the Greenstein credo of reading plenty of material and seeing how others view how to play the game. This way, you learn how to play against people that play a certain strategy, take the good parts, and discard the bad.

More importantly, you spend some time thinking about the game. I suppose the problem is that it's hard to determine bad from good advice. That's also the beauty of all the material out there. [img]/images/graemlins/smile.gif[/img] If you're smart enough, you'll figure it out.
