The main variation is the next series of moves the computer thinks is best. If you want to see what those moves are, press [INFO] twice while the computer is thinking. Then, using the LCD chessboard, the computer shows you its next move (the FROM square and the TO square flash alternatively for three times). After that the computer indicates the move it expects you to make and what move it intends to play after that. At the end of the main variation the computer displays the depth and the evaluation. The evaluation display is in 100ths of a pawn (e.g. “2:00” means that it thinks that White is the equivalent of two pawns ahead). A minus sign in front of the value means that Black is leading.
