and press your king down on its

FROM square (if castling king-

side, E1). Then move and press

your king down on its TO square

(if castling kingside, G1). King

Arthur automatically recognizes

castling maneuvers after the

king is moved two squares. He

then reminds you, by displaying

the proper FROM square, to com-

plete castling by moving the

rook. Move the rook in the rou-

tine manner, pushing on its TO

and FROM

squares normally.

Remember,

you must always

move the King first when castling!

6.3 Promoting Pawns

other than a queen, use King

Arthur’s feature. (See Chapter 9.SETUP)

King Arthur immediately rec- ognizes your new piece, and begins thinking about the posi- tion in order to move. When the computer pushes a pawn to your back row or rank, it will always promote to a queen. Remember to change the piece on the board after either side promotes a pawn. When promoting a pawn to a queen and the original queen is still on the board, chess players frequently mark the new queen with an upside-down rook.

CHAPTER 7:

TOO HARD? TOO EASY? ALL ABOUT LEVELS

When a pawn reaches the other end of the board, official chess rules say that you can pro- mote it to a more valuable piece. To promote a pawn, make your pawn move to the last rank in the normal manner. King Arthur will automatically promote the pawn to a queen, since this is the best choice in nearly every case. In the unlikely event you want to promote your pawn to a piece

6.4 En Passant —

taking a pawn in passing

For an en passant capture,

press the FROM and TO squares

of the capturing pawn. The

square of the pawn being cap-

tured will then appear on the dis-

play. This is to remind you to

remove the captured pawn. You

must press down on the captured

pawn before removing it from

the board.

7.1 Beginner levels

The first four levels (1, 2, 3 and 4) are beginner levels and take approximately 4, 8, 12 and 16 seconds per move, respec- tively.

7.2 Fixed ply levels

Level 5 is a fixed 1-ply (one- half move) search.

7.3 Timed levels

Levels 6 through 15 take about 1 second per level num- ber, so level 10 will average about 10 seconds per move. Levels 16 through 72 take about 2 seconds per level numbers. The amount of time taken will vary depending on the position, the stage of the game, and

whether or not the level

option is on. FAST
