Although in my previous post http://hairulovchessmaniacs.blogspot.com/2007/06/deep-junior-vs-deep-fritz-formula-1-vs.html i mention that the duel between both chess programme were like a formula 1 car competing with formula 3 car, but in game 5, both shows what they sometimes capable for- producing beautiful game.
Usually you watch computer winning boring games and most of the game are plain and dry without any exchange sacrifice or long term strategic plans, but in game 5 of the Ultimate Chess Challenge, you saw a very different kinds of chess by the computers.
Both play a very entertaining games with imbalances position with sacrifice for initiative - not what you usually saw in computer chess games... especially when both playing each other but watch this game:-
