RADIOSHACK PORTABLE 1750L PLAYING LEVELS

BEGINNER LEVELS:  The eight beginner levels let beginning and average players play (and win) more easily than other levels. The computers makes common mistakes such as leaving pieces unprotected, failing to capture unprotected pieces, and capturing pieces while leaving the king unprotected.

FUN LEVELS:  The five fun levels are designed especially for beginners. As in the beginner levels, the computer makes common mistakes at these levels, such as capturing an opponent's pawn by sacrificing it's own higher-value piece.

INFINITE RESPONSE TIME LEVEL:  At the indefinite response time level, the computer searches indefinitely for one move until it checkmate an opponent or 8 ply search depth has been searched. Use this level to have the computer analyze complicated positions for hours or even days.

PROBLEM LEVEL:  At the problem level, the computer searches for one move that will win 2 points or more. NOTE: The computer assigns these point values to the pieces:

• Pawn (1 point)
• Bishop (3 points)
• Knight (3 points)
• Rook (5 points)
• Queen (9 points)

MATE FINDER LEVEL:  The mate finder level lets you set up a position (see Problem Setup) and let the computer try to checkmate the opponent's king within 1 - 4 moves, regardless of the opponent's defense.

PRACTICAL LEVELS:  At the practical levels, the computer attempts t capture opponent's pieces and place the opponent's king in check as often as possible. However the computer sometimes overlooks traps set by an opponent, and sometimes positions its pieces so an opponent can easily attack them.

BRUTE FORCE LEVELS:  The computer normally limits its search to moves most likely to be successful. However, at the brute force levels, the computer checks every move possibility during play.

FIXED DEPTH SEARCH LEVELS: At the fixed depth levels, the computer's search depth is limited by the level you choose. The level number indicates the number of ply (one of your moves or one of the computer's moves) the computer will look ahead to find a move.

PASSIVE LEVELS:  The computer normally chooses opening moves that follow active openings, and open positions. However, you can set the computer so it can choose moves that follow more passive and closed strategies. For example, if you set the computer to a passive level, the computer will avoid attacks and keep closed positions, and might exchange pieces unreasonably, such as its rook for an opponent's pawn. This results in weaker play.

AGGRESSIVE LEVELS:  If you set the computer to the aggressive levels, it will avoid exchanging pieces so it can present more potential attacks to an opponent (to keep the game complicated). It will also check and attack an opponent's pieces in an aggressive manner. This results in stronger play.

NORMAL PLAY LEVELS:  The 8 normal play levels provide the most challenging and difficult play.
