Radio Shack Portable 1750L Sixty Four Level Chess Computer (endorsed by Garry Kasparov - The World Champion). Includes Reproduced Instructions in English and Spanish

Your RADIOSHACK PORTABLE 1750L Sixty Four Level Chess Computer is a relentless and versatile chess opponent. The computer is easy to set up and play. It's features include: * 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. * 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. * 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. Excerpt taken from the "RadioShack Portable 1750L" User Manual
