2. Press the OPTIONS/GO key in the center of the
keys. FrOm will disappearDIRECTION. Time 4

3. Press a key to move the pieceDIRECTIONto the square you want. You’ll see your piece flashing on possible squares as you move it—at the sameto time it continues to flash on its from square.
Note: Press CLEAR to stop a square from flashing in #1 or #3 above, and start the move entry
process over.
4. Press the OPTIONS/GO key again to finalize your move.

WhenScreena ‘+’ appearsSymbolson the screen, it is a reminder that you are in check. When an ‘O’ appears on the screen, the game you are playing can be rated. When an ‘=’ appears, it indicates you are in two human player mode. And lastly when an ‘!’ appears on the screen, you are being warned that one of your pieces is threatened with capture. (This is similar to the friendly "en garde" warning sometimes used by human players when they are attacking an opponent’s queen.)
Generally,Levelsthe ofhigherPlaythe level you select, the better your LCD Chess will play, and the longer it will think during its moves. The first four levels (1, 2, 3 and 4) are beginner levels and take approximately 4, 8, 12 and 16 seconds per move, respectively. Level 5 is a fixed 1- ply (one-half move) search. Levels 6 through 15 take about 1 second per level number, so level 10 will average about 10 seconds per move. Levels 16 through 72 take about 2 seconds per level number. The amount of time taken will vary depending on the position, the stage of the game, and whether or not the FAST level option is on. (See “Level Options,” page 3)
Level 73 is an infinite level. LCD

Chess will take as long to move as you want it to, or until it finds a mate position in its search. Level 73 is good for problem solving (like the MATE problems available under OPTIONS), or it can be used to play against. When you are tired of waiting, press the GO key while the computer is thinking, and the computer will stop thinking and play the best move it’s found so far.

1. Adolf Anderssen vs. Lionel
This marvelousKieseritsky,attackingLondon,game,1851a King's Gambit, is widely known as "The Immortal Game." Both players show the 19th-century preference for attack at all costs, and Anderssen was one of the most ingenious attackers of all time. After 18. Bd6, he gives away both of his rooks and his queen! In the final position, his tiny force is deployed in just the right way to bring the complete Black army to its knees.
2. Adolf Anderssen vs. J. Dufresne,
Again we see Berlin,Anderssen1852bamboozling his opponent. The game starts as an Evan's Gambit, a form of the Giuoco Piano. White's 19th move, Rad1!! is one of the most celebrated in the history of the game. With his reply, … Qxf3, Black actually wins a knight and threatens mate. You'd think that would be enough! But Anderssen follows with a

White gets a and quick
of hisstrongpiecescenter. As early as 13.develRd1,- youopmentcan sense that Black is in danger. His king has no piece defenders; his forces seem passive while White's are aggressively coordinated. As often happens in such situations, White breaks through with a pawn push in the center, in this case 15. d4-d5!. It clears the board for White's more active forces. Petrosian, one of the best defenders of all time, tries repeatedly to trade queens, but White wisely rebuffs these offers, which would take much of the power off the board. White's d-pawn becomes a star, advancing all the way to the 7th rank. Because of this queening threat, White is able to sacrifice his queen for one of Black's defending rooks. In the final position, it's hopeless for Black because White will either promote his pawn to a queen or capture whatever Black uses to block on d8.
15. Robert Fischer vs. Reuben Fine,
Nine years beforeNew winningYork, 1963the world championship, Bobby Fischer played this Evan's Gambit (a variation of the Giuoco Piano) against his famous elder. Bobby sacrifices two pawns in order to get his pieces out quickly. Then he plays 14. h2-h4!, sacrificing another pawn to force the Black queen away from the g7-square. After that, Black's king will be stuck in the center and in danger of the h4-d8 diagonal. Bobby's final move, 17. Qg3!, forces Fine to resign, because he must move his queen from the critical black diagonal h4-d8. Even on 17. … Qxg3, White ignores the capture of his own queen and plays 18. Bf6 mate!
16. Lajos Portisch vs. Johannessen,
During the firstHavana,half of this1966game, a Queen's Gambit Slav, the great Hungarian grandmaster Lajos Portisch locks up the center with a d4-e5 structure by move 14. This gives him a "beachhead" on e5 and makes it hard for Black to counterattack in the center, which is the standard antidote for an attack on the wing. The next stage starts with 16.
14
h4. Portisch announces his intention to attack on the kingside. He refrains from castling his own king into safety because he knows it’s safe enough in the center, at least for the time it will take him to break through with his attack. When Black tries to trade off pieces with 17. … Bxf3, Portisch sacrifices a knight for an unstoppable attack with 18. Bxh6 and then calmly moves his king to the second rank to bring his other rook into the game. His Rxh4 was another brilliant sacrifice that crushes any hope of defense. In the final position, Black resigns because White will simply play 26. Rxh6+, winning the Black queen. If 26. … Qxh6, then White plays 27. Qxh6+ and will mate on h7.

DOCKER
ACCESSORY
Model 975D
An amazing feature of the LCD Chess, is that it can be connected to a sensory chess board and used with real chess pieces. If you purchased The Excalibur Chess Station, the chess board DOCKER was included with the pocket LCD Chess unit. If you purchased only the pocket LCD Chess unit, con-
tact Excalibur Electronics to order the DOCKER accessory.
To attach the LCD Chess to the DOCKER, first make sure LCD Chess is OFF. Turn the LCD Chess upside down so the cover is nearest you and the batteries are furthest away. Remove the cover using your thumb nail to pry off the cover (see
item 1, right). Now notice the central protruding tip in the middle of one edge of the cover. Then locate the two small protruding dimples on the other edge of the cover.
Insert the protruding central tip in the slot on the back of the LCD Chess with the edge having the two dimples positioned next to the silver name plate (see item 2, below). Now with one hand, place your thumb where the protruding tip was inserted, and two fingers on the two dimples. Push down with your thumb and use your two fingers to GENTLY pull the two dimples toward your thumb a little. This will lock the cover into place. To remove the cover from its storage slot, use your thumb and finger to work it out of its locked position.
Locate the three plastic bumps just above the Excalibur logo on the front of LCD Chess. Now slide the LCD Chess into the DOCKER until the three plastic bumps are just visible above the plastic chute of the DOCKER.
After you have inserted LCD Chess into the DOCKER, set the chess pieces (included with the DOCKER) on their starting squares. Use the chess board screen of LCD Chess as a reference, in case you are unsure where a piece goes. Don’t forget the queen always goes on her own color square.

of square E4. Place the pawn on square E4.
LCD Chess will respond with its move by showing the from and to square coordinates on the display. LCD Chess will wait until you move its piece by pressing on the from square and then the to square.
It is now your move.
LettingAfter youLCDmakeChessyour moveGo Firston the DOCKER, LCD Chess knows you are connected to the DOCKER. It then will wait for you to press its from and to squares when it moves. But when you want LCD Chess to go first and play the white pieces at the top of the board, you simply press the GO key on LCD Chess. LCD Chess does not know you are using the DOCKER, so it assumes that you are not. Therefore it simply moves its piece on the LCD Chess board, and assumes you will make its opening move on the DOCKER chess board without pressing on its from and to squares.

When youSpecialcastleMovesyour king on the DOCKER, LCD Chess will remind you to move your rook by display- ing the from and to squares. Move the rook in the routine manner, pressing on its from square and then its to square. When LCD Chess castles, it will also remind you to move its rook.
For an en passant cature, press the from and to squares of the capturing pawn. The square of the pawn being captured will then appear on the display. This is to remind you to remove the captured pawn. You must press down on the captured pawn before removing it from the board.
When you undo a move on the DOCKER, you must follow the standard procedure of pushing on the to square and then the from square. When the move is a capture, LCD Chess will also then signal the capture square. Refer to the chess board on the LCD screen for the proper piece to press on the capture square.
If you attempt an illegal move on the DOCKER, you must follow the standard procedure of undoing the illegal move by pushing on the to square and then the from square.
Interrupting a Game
If you are in the middle of a game using the DOCKER, but want to continue the game with only the LCD Chess, just turn off LCD Chess when it is your move. Disconnect LCD Chess from the DOCKER, and turn on LCD Chess. You may now continue your game using the DIRECTION keys to enter your moves.
You may also finish the game on the DOCKER by turning the LCD Chess off, and inserting it into the DOCKER. Turn on LCD Chess and arrange the pieces on the DOCKER chess board to match the chess pieces on the LCD Chess screen.
Note: Do not take-back a move on the LCD Chess until you have made a move on LCD Chess using the DIRECTION keys. Entering your move on LCD Chess tells LCD Chess that you are no longer using the DOCKER.

you wish to change, simply press the square. If you are removing a piece, that is all you need to do. If you are changing or placing a piece on a square, the first time you press the square a black piece of the type you have selected will appear. Press the square once more and the color of the piece will become white. If you made an error and want it to be black instead, just press on the square once more.
