Yes, if both moves are equal, you should obviously choose the one that improves your position in 3 ply. It is somewhat likely that a program will choose this move, too, because it did a 3 ply search and determined that move to be the best. The subsequent searches _assume_ that move is the best, and will probably keep it. However, if the program thinks the 5-ply move is slightly better, it will play the 5-ply move. -Tom
