BlindChess learns you to calculate moves in advance. For blindchess first select the blindchess level in the settingsscreen.
Depending on the level you select (between 1 and 8), you see the number of moves you should calculate in advance. The higher the level, the more difficult the exercises will be. This challenge is perfectly suited for very experienced players. Based on the position you have calculated, you should try to find the best move. Like the realchess challenge, the best move can be either a defending or winning move. Some moves are very subtle and difficult to find.
