Mates in 1 to 5 are usually found relatively quickly, whereas solutions taking 6 to 8 moves make take quite some time. If there is no mate present or if the computer cannot find a mate, it will sound the error beep.

In a few seconds the computer will show you the solution: 1 a8=B (underpromotion to a bishop!). Try the defenses 1. . . . Kf8, 1. . . . Ke8 and 1. . . . Kg8 to see how White mates on the third move. 3. 7 Instantaneous replies All times given for the different levels of skill are average times over a large number of moves. Depending on the stage of the game and the tactical complexity of a position, the computer may take considerably more (or less) time on individual moves. If you have just made a move and the BLACK light is flashing (or the WHITE if the computer is playing with the white pieces) this means that the computer is thinking. This is how to interpret the display: Light Meaning 8 White has a winning position 7 White has a clearly better position 6 White has an advantage 5 The position is balanced 4 The position is balanced 3 Black has an advantage 2 Black has a clearly better position 1 Black has a winning position You can watch the evaluation change as the computer looks more deeply into the position. Note that the INFO display (best move or evaluation) is retained throughout the game, in fact even when you start a new game. This function is not available in Mate Seach levels as computer use different search algorithm. 4. ADVANCED FEATURES What we have seen so far is enough to give you countless hours of pleasure with your chess computer. You can play straight games against it, correct mistakes and adjust the level of skill to match your own. But there are many other things the computer can do that make it even more fun to use. 4. 1 Non Auto Normally, as soon as you have made a move on the sensor board, the computer immediately begins to compute its reply. For instance you may want to try a special opening against the computer, one it doesn't play of its own accord. Or you may want to force it to play a certain continuation in order to understand a complicated position. This puts the computer into a special mode in which it will not compute a reply, but only keep track of the moves you enter, making sure that they are legal. Pressing NEW GAME always cancels the function. An experiment with INFO Press NEW GAME and NON AUTO, and then enter the following moves: 1. Press INFO and watch how the computer keeps changing its mind until it finds a really good move (5. Nf3xe5!). Experiment with the position to find out why the white queen may not be captured after 5. Nf3xe5. [. . . ] Only batteries of the same or equivalent type as recommended are to be used.
