What is the difference between Fritz and Rybka?
Fritz and Rybka are both incredibly strong chess engines. Both are strong enough to beat the strongest human grandmasters. Both utilise all the training features of the chessbase user interface. The main difference is that Fritz disk contains sample videos from the Chessbase multimedia DVDs that are available from our shop. They do play with different styles, and may suggest different (very strong) moves in the same situation. In the current (Dec 09) computer engine rating lists, Rybka is above Fritz.
