The completely reworked "friend" mode makes Fritz 15 the ideal training partner. During the course of a game, Fritz is able to constantly tailor its level to your playing strength and how much time you are using. The program can give you a sign when a tactical opportunity presents itself or point out typical mistakes to help you improve. Another exciting element is the new evaluation function that analyzes your playing strength throughout the game. Where are your strengths - where are your weaknesses? The opening? Middlegame? Or perhaps the endgame? Fritz 15 gives you an ELO rating for all three phases. You definitely need to see this.
