against the stiffer opposition of a higher level.
Level B1 is the weakest level. On this level, the value
of material is set so that the computer will not only "hang"
pieces (leave pieces unguarded), but will also actually try
to lose material. Watching the computer throw away its
Queen would not even be uncommon on this level! Levels
B2, B3, and B4 are similar to B1, in that they also give
away material, but they do not do it as consistently. They
progressively start to consider the material worth of
pieces more and more, and Level B4 only occasionally
gives pieces away. On Fun Level B5, the computer does
not actually give away material—here, it plays more like a
beginner who has learned the basics of the game. On this
level, the computer makes mistakes such as bringing out
its Queen too early, leaving its pieces unguarded, and
opening itself up to threats of check and/or checkmate.
Why not try out all the Fun Levels—and try to learn from
the computer's mistakes!

On the Infinite Level, the computer searches indefi-
nitely, until it finds a forced mate, runs out of memory, or
until you stop the search by pressing PLAY. If the search
is halted, the computer makes the move it currently thinks
is best. Try experimenting with the Infinite Level—let the
computer analyze complicated positions for hours or even
days!
3.4 Combination Finder Level (B7)
Combination Finder Level
Square B7 .......... Solves chess puzzles
The Combination Finder Level is used for solving "mate
or a large win of material" problems. Here, the computer
looks for the shortest forced win of two pawns or more. In
order to come up with a solution, the computer must see
a win of enough material to be two pawns better than the
current position. If it finds such a solution, it will beep and
indicate its move.
If the computer reaches its search depth limit without
finding a solution, it beeps and the previously flashing
color indicator turns on steadily. To continue play, change
levels—then either press PLAY to have the computer
