With Rebel 9.0 it was time for something new. Knowing our program performed better against humans than computers why not step into the footsteps of Deep Blue that beat Gary Kasparov that year? And so we challenged Arthur Yusopov the then current number 10 of the world according to the FIDE rating list. Rebel won with 10½-6½. The match took place in Italy and has its own page.
