Fruit versus Rybka could turn out to be a one of those classic sports rivalries (yes, chess programming is a sport), because it pits different kinds of expertise against each other. Rybka's author is obviously a great programmer and chess IM, but Fruit's author may be the best chess coder alive. Maybe they should join forces and collaborate. :) Roger PS. I suspect Fabien called his program Fruit because it was yielding something good, as in "bearing fruit," but who knows.
