Of course, you could have the program randomize between move of close values : most programs can already do that, again to add more variety. Though it is possible that it weakens the program a little. In most position, there are usually more than one good and sound move (else chess would be like Tic Tac Toe). But the lack of variety would still be smaller than with an opening book. It could also fall into a known opening trap that cannot be calculated because the lost it is too far ahead! Finally, would you create a way for the program to "learn" from what it played? Serge Desmarais P.S. When I play a blitz against a computer, I hate it when it does stay in book for many moves, not EVEN taking one SECOND (or exactly one second!) per move. Just moving the mouse to play takes time! So you are at a big disadvantage...
