Fritz Technique Trainer 2
Winning won positions – this vital chess skill can be aquired and improved with the CDs of the Fritz Technique Trainer series. “ The tasks on this CD deal exclusively with the creative work of the first official world champion, Wilhelm Steinitz. He was the first to describe the fundamentals a promising attack is based upon. Thus most exercises are about showing how a successful attack is conducted” (Schlössner). Each exercise starts with a won position from a Steinitz game which you are to play against Fritz. It is rarely about finding combinations to solve the problem. Usually the win can be achieved in different ways. But there are always a few obstacles to be swept out of the way, and then you will always experience the sweet smell of success. This is what makes chess training fun: 121 winnable game positions explanations as to how to go about things appropriate examples of how to win classified according to difficulty
The author Henrik Schlössner has already produced the tactical database for the Tal-CD, and he is the author of the predecessor version Fritz Technique Trainer.
