At the beginning of the game, you may select one of sixteen of the word’s greatest chess games by pressing 2nd, then OPTIONS, and then pressing the LAST PIECE or NEXT PIECE key to select a game number.
Along with the game number you will see the position of the game after the first two moves were played. Press the CLEAR key to return to normal play starting at move three. You take the winning side. The display will show your total great-game score in two digits (zero at the start) on the left. On the right, the display also shows the amount of points you will win if you play the correct next move.
If you don’t play the correct great-game move, an error buzz will sound and the points for this move will be divided by half. If the bonus goes to zero, the correct move will automatically flash. Most moves start with 4 bonus points, but some brilliant moves start with 8 points.
HOW TO CHANGE LEVEL OPTIONS
When the level is displayed, pressing the OPTIONS key shows:
FAST: In this mode, 2-in-1 e-Chess & Checkers uses a more selective search for thinking. It may miss a tactical move, but it can look more deeply into the position. Press NEXT PIECE to turn FAST on or off. Or press the OPTIONS key again to show:
rAnd: Allows the computer to randomly choose between two good moves so that you get to practice and play against different responses. Press the NEXT PIECE key to turn random on or off.
CHECKERS (Changing games)
Whenever CHESS is shown on the display, you may change to Checkers by pressing the 2nd key, and then pressing the NEW GAME key. The LCD display will show O1CHECr and will also show the checker board with all the pieces on their starting squares.
There are 15 levels of play for checkers varying from 1 second to 60 seconds per move. Level 16 is an infinite level.
