REFEREE Key
This is a toggle function which allows the user to play a game on the computer with the computer only checking the legality
of the moves and declaring DRAW, CHECK MATE, and STALE MATE. This is also how games can be entered into the
computer to be analysed (see ANALYSE function).
All games played could be stored in one of the 64 games slots (see STORE GAME) or could be entered for processing to a
PC (see INTERFACE).
The LCD display will show [rEF] where REFEREE is off and [rEF
≡
] when REFEREE is on. The first press shows the
current status of REFEREE. Press the REFEREE key a second time within two seconds that the REFEREE message is on
the LCD display to change that function. The REFEREE mode may be selected at any time during a game except while the
SAPPHIRE II is computing.
Note: The SAPPHIRE II may be called upon to compute for the side to move by pressing the GO key.
All features are available whilst REFEREE mode is on.
5.
HINT Key
The SAPPHIRE II can suggest moves if you are not sure how to continue your game. This is a great tutoring feature. When
pressing the HINT key you may recall the following information:
ON YOUR MOVE :
Pressing the HINT key when it is your turn to move will show the move which the computer thinks is your best move.
Pressing the GO key while the computer displays the first Hint, makes the computer accept this move as though you played
it. You may make also a move of your own choice whilst any Hint is being displayed.
Note: The displayed Hint move is the move which the computer is thinking on when EASY is off.
WHILE COMPUTING :
If you press the HINT key whilst the computer is calculating, the display will show the move the computer thinks is so far
the best for itselft.
Press HINT key to display the move(s) being considered by the computer as the best line of play up to 9 ply (the display
shows the "from" and "to" square of the considered move and [h int#], where # represents a number from 1-9 showing the
depth of the move).
−
Press HINT to cycle through the best line.
−
Press CLEAR to remove the Hint display.
−
Press GO when [h int1] is displayed during the human's turn to play the Hint move on the board.
6.
TRAINING Key
This function is provided for the novice player. It could be useful for the novice player who is in check and does not know
what choices he or she has to get out of check.
Step 1:
When it is your turn to move press the TRAINING key and the computer will show the "from" square
(indicated on the LCD) of the first piece with a legal move.
If you continue to press the TRAINING key, the SAPPHIRE II will show you all pieces with at least one
legal move. You may cycle through this step as often as you wish. When no more pieces are available to be
legally moved, then the display shows [ ].
Step 2:
Once you have selected a piece, press GO to have this square accepted as though keyed in. If a "from"
square has been entered then each press of the TRAINING key will show now each legal "to" square by this
piece.
Step 3:
If you accept the move as displayed, press the GO key and the computer will then make its counter move.
If you wish to make a move other than displayed, clear first the display by pressing the CLEAR key and then
execute the move of your choice.
Should you wish to go back to Step 1, use the CLEAR key to reset the LCD display and then press the
TRAINING key to go to Step 1.
