The red squares refer to the move's weight, which can be used to determine the
move's probability of being selected. One "square" is a weight of 25. Two
squares is a weight of 50, and 3 squares is a weight of 100. Zero squares is, of
course, zero weight, and a move with zero squares will never be selected.

This is from the "Gameplay FAQ", which you can find on the Chessmaster website:

------------------------
If there is more than one move available for a given position, then the chances
that a particular move will be made are based on that move's weight AND the
weights of all of the other moves for that position. The formula is to add up
the weights of each of the moves and then divide each INDIVIDUAL move's weight
by the total to determine the percentage chance that a move will be selected.
Examples:
-- In response to 1.e4, you have the choices 1...e5 and 1...c5, each with a
weight of 100. This means that 1...e5 will be chosen 50% of the time (100/200)
and 1...c5 will be chosen 50% of the time (also 100/200).
-- Let's say you add 1...d5 as another response to 1.e4 (in addition to 1...e5
and 1...c5 above), but you give it a weight of 25. This means that 1...e5 and
1...c5 have about a 44% chance (100/225) of being made, and 1...d5 has about an
11% chance (25/225).
