$move_c = $clone->make_move("e2", "e4");
$true = ($move->get_piece() ne $move_c->get_piece());

The Chess module provides a framework for writing chess programs with Perl. This class forms part of that framework, providing move validation for all moves recorded using the Chess::Game class. The Game contains a Chess::Board, 32 Chess::Pieces and a Chess::Game::MoveList that contains a series of Chess::Game::MoveListEntrys that record the exact state of the game as it progresses. Moves can be taken back one-at-a-time to allow for simple movelist manipulation.
