My little brother has shown a real knack for poker over the last few months and wants to improve his game. He's still in high school and mostly plays private, micro-to-low stakes NLHE/Omaha cash games along with online NLHE tournaments. If I were to get him one book, which should it be? SSHE was my first thought, but he doesn't play limit...
