I am sure that they tried at home also to play their normal opening against the machine and found that it is not the best idea. Remember that a GM is involved in the book of Deep Junior and I will not be surprised if he prepared lines against the opponent regular moves. I think that you are wrong to assume the same conditions about Deep Junior and many programmers. Uri
