2b. The other game where Kramnik launched a king Attack, the same scenario the
center was locked, therefore Deep Junior did not have to Castle on move 6.
it could have waited, since the king was not in immediate danger it could
had played Nf6 and then develop the Queen bishop. The point here is that
Kramnik was just waiting to see where the program was going to castle, and
then mobilize his pieces slowly toward the king, preparing a king side
attack, now if the program did not castle, with the center closed it
would have been a hard wall to break with all DJ pieces surounding the
king.
