Poker is in constant evolution; the players get smarter and the games get tougher. As this happens the need for having a fundamentally sound game is greater than ever. In order to keep up with modern developments, players must constantly be willing to adapt and learn new strategies. However, with so much new software available and so many new theories about play, it's difficult to make sense of it all. Modern Poker Theory is the solution to this problem. It is a comprehensive, rigorous guide to the most important aspects of No Limit Hold 'Em. Modern Poker Theory uses modern poker tools to develop a systematic approach to game theory optimal play (GTO). It organises the ideas and concepts in an intuitive manner that is totally focused to practical applications. The goal is to help players improve their understanding of the game while providing them with the skill set they need in order to stay ahead of the curve and beat the games.
