There are options in Rebel to tell it to look at a move in its book (well, in the EOC actually) and then determine if there is a significantly better move it can make. It avoids nasty situations where even 2600+ players played a really weak move and the pgn game collection you pulled that game from doesn't give you a "heads up" that the move played was weak. Rebel can avoid making the same blunder the GM did even though that game is in the EOC. Roy
