DESCRIPTION

A Chess::Opening::Book::Move is one of the possible moves listed for a certain position in a Chess::Opening::Book.

Each move has a "weight" resp. "count" property that specifies the number of times that move has been successfully played for a specific position. You can compare this information with the weight of other moves for the same position in order to estimate the likelihood of success, when picking this move.
