3. SELF-PLAY MODE

N/A

There is a way to make the computer automatically play an entire game against itself - you don’t have to press a key for each move. Press [FUNCTION] [PLAY] [PLAY] and the computer automatically makes moves for both sides and displays the moves on the display. You don’t have to move the playing pieces.

If you want to interrupt the computer’s play and make moves manually, press [ANALYSIS] [NORMAL]. If you do this however you should set up the pieces as shown in the display.

4. THE MAIN VARIATION AND POSITION EVALUATION

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] while the computer is thinking.

Then, using the row/column indicators, the computer shows you its next move (the FROM square is indicated for two seconds and the TO square for one second). After that the computer indicates the move it expects you to make and what move it intends to play after that.

After showing you the main variation, the computer turns on one row indicator (on the left side of the board) to indicate what it thinks the outcome of the game will be based on the current piece positions:

  1. Winning for the computer.
  2. Strong material advantage for computer.
  3. Positional advantage for the computer.
  4. Slight general advantage for computer.
  5. Slight general advantage for player.
  6. Positional advantage for player.
  7. Strong material advantage for player.
  8. Winning for player (normally white).

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.

The above examples from their user manuals clearly show that there is a difference in the display functionality. Model 60-2204A seems to have an improved evaluation. The above are some examples. There are a few additional differences shown in the respective User Manuals.
