Draughts

Rules: The game uses the generally accepted rule that if there is a piece to take then you must take it. You must also take any further piece then takeable from your new square. This rule is enforced by the program, and messages appear to tell you when you must take.

Incidentally, messages are printed in your chosen colour, in case you should forget on which side you are playing!

End Of Session: To leave the program simply press BREAK. Pressing ESCAPE will not work at any time.

1. Choice Of Colour
After loading, you should get a board and a "Black or White?" message. Respond B or W and the board will be set up for you. If you selected White, the computer will also have made its random opening move, and the message "Level 1" will be shown (See 3).

2. Entering Your Move
At bottom left there is a cursor. Its movement is controlled by the four arrow keys.

The keys repeat at intervals of 1/5th second.

Simply position the cursor on the square you want to move *from* and press Space bar, the move over the square you want to move *to* and press Space bar again. If your move was a legal move, the move will be shown and the computer will start considering its reply. If your move was illegal in any way, the cursor will return to bottom left and you must try again.

3. Changing Skill Levels
There are two levels available. Level 1 is fast (a few seconds) and quite difficult to beat without cheating (See 4). Level 2 is much slower - though times very greatly - and plays a very skilful game. To change between one level and the other, press L at your turn.

4. Move Recall
Pressing R withdraws your last move and the computer's last move. You can re-enter any legal move. This feature is very useful if you wan tthe computer to make a more considered reply to your last move. Press R then L (for level 2) and re-enter your move.

5. Problem Solving
The game has sophisticated problem-solving features which are accessed by pressing P. The message Set Position is also issued. The following features are now available to you:

Cursor - behaves normally
Key 0 - deletes the piece under the cursor
Key 1 - inserts one of your pieces (No need to press 0 first)
Key 2 - inserts one of your kings
Key 3 - inserts a computer piece
Key 4 - inserts a computer king
Key C - clears the board completely
Key Q - the computer will reply to the new position and you can continue playing normally as long as you like, but
Key G - restores the position when you last pressed P, so you can get back to your game providing you have only pressed P once.

6. Re-starting
If you want to abandon the present game and start a new one press S. This is final, there is no going back to the previous game!
