Partner 1680X Chess Computer (600-2428A) Study Positions Faxback Doc. # 17072 USING THE STUDY POSITIONS Your computer has 8 built in chess study positions that you can try to solve with its help. These study positions are intended to entertain you and improve your knowledge of chess. You can select any study position, analyze it carefully, and try to find correct moves for white. The computer knows the principle lines of attack as analyzed by chess masters, so it can help you solve the study position. NOTE: When using the study positions, the computer automatically sets itself to level B7 (L-3E) and the coach function. For more information about levels, see "Play Levels". For more information about the coach function see Coach Function." Follow these steps to use a study position. 1. Repeatedly press STUDIES until you see the study position you want (1 through 8). The computer displays St n, , is the study position number (1 through 8). The computer loads one of the move series for the study position you choose into its memory 2. Set up the board as shown in the diagrams in "About the Study Positions" for the study position you selected 3. Press STUDIES 4. Once you select a study position, enter a move. Or, select the first move from a series for the study position you choose, then enter the move If the move you made is in a move series within the computer's solution library, the computer will make a countermove, and play continues. If your move is not in the computer's solution library, the computer beeps and displays "oob", indicating that your move is out of book, and the computer will not play a countermove. Press TAKEBACK to take back the move and try another move. When you play the correct move, the computer will countermove with the best defense for black. If you cannot find the solution yourself, press PLAY. The computer shows you how white should play. ABOUT THE STUDY POSITIONS For a list of move series for all study positions see "Study Position Move Series." Study Position 1 :White to Play and Win Study Position 1 illustrated how to checkmate an opponent's single king with a limited number of pieces. In Study Position 1, the white king and white rook must work together to trap and checkmate the black king, From this position, white can checkmate the black king in as few as 8 moves. This study position has 2 separate series of moves. Study Position 2: White to Play and Win Study Position 2 illustrates the strategy of "gaining the opposition." In order to promote a pawn, the white king must first gain opposition. Advanced players know that 2 kings are facing each other on the same rank or file with only 1 empty square between them, then the player waiting to move is said to have the opposition. Gaining the opposition is almost always an advantage in pawn endgames, since it allows a player to gain territory and penetrate the opponent's position. This study position has 3 separate series of moves. Study Position 3: White to Play and Draw Study Position 3 illustrates the strategy of "drawing." Knowledge of Study Position 2 should help you understand this strategy. white, in grave danger of losing, must play a surprising move to deprive black of the opposition and hold black to a draw. This Study position has 2 separate series of moves. Study position 4: White to Play and Win Study Position 4 illustrates the "skewer" strategy. If the black king moves to the 6th rank, white can check with the rook, promote a pawn, and win very easily. The black king and black rook are forced, into a fatal line up along the 7th rank, after which white uses a deadly skewer to win the black rook. Without knowing this tactic, white could not win the game, despite a 3-pawn advantage. This study position has 1 move series. Study Position 5: White to Play and Win Study Position 5 was taken from the game Capablanca- Tanerow, New York, 1910. The white queen is attacked by Tanerow's black bishop on E5. Capablanca, who was the champion from 1921 to 1927, took just a few brilliant moves to defeat Tanerow. Can you find them? This study position has 1 series of moves. Study Position6: White to Play and Win Study Position 6 was taken from a game between the American genius Paul Morphy and the Duke of Brunswick, which was reported to have taken place during and opera! Even after you have found the correct attack, you should play through Study Position 6 more than once, since the computer will try different defenses for black. This study position has 5 separate series of moves. Study Position 7: White to Play and Win Study position 7 was taken form the game Alekhins- Grunfeld, Carlsbad, 1923 (with the colors reversed), which "some competent critics have considered the finest ever played," according to chess grandmaster Reuben Fine. Since the computer will try different defenses for black, you should play through Study Position 7 more than once. This study position has 3 separate series of moves. Study Position 8: White to Play and Win Study Position 8 was taken from the game Edemas-Torre, New Orleans. 1920, and contains a series of astonishing sacrifices of great beauty and originality. White could give "black- rank mate" if square E8 were not so well protected, Therefore, white attempts to divert the black queen or the black rook on C8 from their defense of this square. If you do not understand the moves the computer plays black, try playing other moves against the computer. Select Study Position 8, press PLAY, make a different black defensive move, then press PLAY, again. You will soon realize why black was so cautious. This study position has 2 separate series of moves. About the Solution Library Your computer has a built-in solution library that contains one or more series of solutions for white and black for each study position. Each series contains one possible sequence of moves and countermoves during a chess game that, if followed, will result in white either drawing or checkmating black. The solution library contains at least one series of suggested moves for each study position. When you play a study position, the computer selects one of the series of suggested moves for the study position at random. NOTES: If you want to let the computer show you the suggested moves for both white and black while playing a study position, press PLAY before each move. The computer shows you how white and black should play. When you make all of the moves in the series (while pressing PLAY), the computer displays "oob" and beeps several times. You must then make the final move to checkmate black If the computer displays "oob" and beeps once when you make a suggested move, the series you are playing might be the wrong one. Look at the next series within the same study position, then try the move for the color you are playing next to the move sequence number you used in the previous series The computer's solution library contains the following moves.
