You are correct Dave, and the reason why Kramnik is trying so hard to exchange
the queen early is to avoid complexity, since with the presence of the Queens on
the board when the position becomes tactical and open like yesterday game, with
the extra Queen having the biggest possible number of moves it makes it harder
to beat Deep Fritz tactically. You will notice later on that if the queens are
not exchange, kramnik will switch to a strategical game instead of a pure
tactical one.
