228 Fritz 15 Help backwards with the arrow keys. At any stage you can enter new variations. However the pieces on the board always remain fixed in the starting position. Calculation training offers you different levels of feedback: From left to right Arrow le ft takes one move back. T he c urv e d a rrow retracts a move for quick correction: The next move you enter will overwrite the retracted move without the usual query. Arrow right executes a move in the notation. T he gre e n c he c km a rk checks all moves for legality. Like in real calculation you may enter illegal moves. You can start the engine for interactive analysis. However the board will still remain in the starting position. Good for tactical checking without moving the pieces. Sc ore t he qua lit y of y our c a lc ula t ion: This will take a while. The engine examines every move you entered and assigns a point score. Simple moves will get one point, strong moves four points and tactical oversights will score negative values. Ne w c a lc ula t ion – deletes all previous lines. Quit calculation training ends the current session and, if you wish, merges your variations into the game notation. © ChessBase 2015
