Can anyone please tell me if Doyle Brunson's Super system 1 and 2 is worth reading for today's modern poker games? Also David Salansky's Theory of poker and NLHE cash game books. When i buy books i tend to just buy books that are no more than 2 years old, so i'm just curious if i'm missing out by not having read such popular yet old books. Thanks so much and good luck at the tables!
