The Fritz Powerbook 2011 contains 23 million opening positions,
derived from 1.5 million high class tournament games. Together with
each position all relevant information is stored: all moves that were
played in the position, by players of what average rating, with what
success and performance results. The games from which the Fritz
Powerbook 2011 were derived are also included on the DVD. This means
that in any position of the openings tree you can load and replay the
games in which the position occurred. The Fritz Powerbook 2011
represents the state of the art of current openings theory. Discover
exciting and tricky new lines and practice them against Fritz. In
addition the DVD has a small but very exclusive book with the
strongest GM games (ELO >= 2550) from the past 100 years (2 Mio
positions).
