Master 2200X Chess Computer
(600-2213) Play Levels Faxback Doc. # 47016
When you play against the computer, you can select a play level that
matches your skill level. You can also select from many time-controlled
play levels, including several that simulate tournament play. Some of the
levels even let you use the computer to learn chess strategies or analyze
chess problems.
The 64 different play levels include:
16 training levels (A7 through H8)
8 mate search levels (A6 through H6)
8 beginner levels (A5 through H5)
8 sudden death levels (A4 through H4)
8 tournament levels (A3 through H3)
1 indefinite response time level (H2)
15 normal play levels (A1 through G2)

When you install batteries or press ACL to reset the computer, it resets
itself to level D1. After that, the computer remains on the last selected
level.
To see the current level, press LEVEL. The computer beeps and the display
shows the code for the current level.
LEVEL CODE DISPLAYS
When you select a level, the display shows information about that level.
For example, if you choose level B2, the display shows L 1:00. L means
that the computer is set to a normal play level, and 1:00 (one minute) is
the maximum amount of time the computer has to calculate each move during
a game. See "Choosing a Level" below.

CHANGING THE LEVEL
To change the current level, press LEVEL, then press the square on the
game board that corresponds to the level you want. Or, press []/< or []/>
until the display shows the level you want.
To quickly move through the levels, repeatedly press LEVEL to skip over
eight levels at a time.
When the computer displays the level you want, simply press ENTER, then
continue the current game. Or, press CLEAR to remain on the last selected
level. You can change the level at any time during a game.
CHOOSING A LEVEL
If you are a beginner, start out with the beginner levels (A5 through H5)
or training levels (A7 through H8). The computer purposely makes mistakes
on the beginner levels so you can beat the computer and learn while you
play. The training levels restrict the computer's search depth, resulting
in weaker play.
If you are an intermediate or advanced player, try the normal play levels
(A1 through G2). These range from easy all the way up to difficult.
Note: When you set the level, keep in mind that the more time the
computer has to think about its moves, the better it plays.
Beginner Levels (A5-H5)
The eight beginner levels let beginners and average players play (and win)
more easily than in other levels. The computer makes common mistakes such
as leaving pieces unprotected, failing to capture unprotected pieces, and
capturing pieces while leaving the king unprotected.
Level A5 is the easiest, and the computer's playing strength increases
gradually up through level H5.
The following table shows:
The square you press to select the level (after you press LEVEL.)
The average amount of time the computer takes to determine its move

E5 5 seconds bEG: 5
F5 6 seconds bEG: 6
G5 7 seconds bEG: 7
H5 8 seconds bEG: 8
Note: The time-per-move figure is the average time the computer takes to
make a move. During the opening moves of a game, the computer
might move more quickly.
Training Levels (A7-H8)
The 16 training levels are designed especially for beginners. At the
lower training levels, the computer moves almost instantaneously, not
allowing itself to study a move in any depth.
Level A7 is the easiest, and the computer's playing strength increases
gradually up through Level H8.
The following table shows:

Normal Play Levels (A1 - G2)
The 15 normal play levels increase in difficulty from level A1 (the
easiest) to level G2 (the most difficult).

G2 10 minutes L 10:00
Note: The time-per-move figure is the average time the computer takes to
make each move. During the opening moves of a game, the computer
might move more quickly.
Tournament Levels (A3 - H3)
At these levels, you must make a specified number of moves within a given
amount of time. If you exceed the allotted time before making the
specified number of moves, the computer beeps, tImE flashes on the display
with the elapsed time, and the game is over.
Notes: When you play at a tournament level, you can set the computer's
chess clock to display the count-down time instead of the elapsed
time. See "Count-Down Clock (E1)" in Faxback Doc. # 47019.
When you play at a tournament level, the computer times itself and
you. See "Remaining Time in a Sudden Death/Tournament Game" in
Faxback Doc. # 47018.

Sudden Death Levels (A4 - H4)
At these levels, you must finish the game within a given amount of time.
If you exceed the allotted time, the computer beeps and tImE flashes on
the display with the elapsed time.
Notes: When you play at a sudden death level, you can set the computer's
chess clock to display the count-down time instead of the elapsed
time. See "Count Down Clock (E1)" in Faxback Doc. # 47019.
When you play at a sudden death level, the computer times itself

Mate Search Levels (A6 - H6)
The eight mate search levels allow you to set up a position (see "Problem
Setup" in Faxback Doc. # 47017) and let the computer try to checkmate the
opponents king within 1 to 8 moves, regardless of the opponent's defense.
The computer searches for the shortest possible solution to checkmate
problems. If no checkmate is possible or the computer cannot find a
checkmate, it sounds an error beep. Then you must change levels to return
to normal play.
The following table shows:
The square you press to select the level (after you press LEVEL).
The mate problem the computer will try to solve.

F6 Mate in 6 ( ) in: 6
G6 Mate in 7 ( ) in: 7
H6 Mate in 8 ( ) in: 8
Indefinite Response Time Level (H2)
At H2 (the indefinite response time level), the computer searches until it
finds a forced mate or you stop the search by pressing ENTER. Use this
level to have the computer analyze complicated positions for hours or even
days.
When you select this level, the computer displays 9:99:99.
To stop the search and force the computer to make a move, press ENTER.
