That is apparently the best chess software market with a bank of 1 million parts. Who says better? It is unbeatable or perhaps by players of good level. Yes, but. It might be more flexible to use for players Sunday. It is, for example, impossible to play a part and show parts of the library. When small player, you try to progress in the study of openings, it is frustrating not being able to access the library to learn the strokes suites. Take a break during the game is impossible, we must go to the end of the game or give up; therefore impossible to be distracted or have a coffee during the game. When classes give by Marie Sebbag video is the full horror: 1) it could have taken pedagogy courses before. 2) it could prepare for it, his performance is dismal (I better get it), 3) one wonders if it is for kindergarten children or adults (what is the public? 4) in short, is not viewable. We do not understand that we have chosen for these courses so that there are so many good players in France. So a relative disappointment. Chessmaster is what is best for players below 2200 ELO? I do not know. So Fritz still has a bright future .... for improvement.
