If you have been following the threads giving analysis, you would know that the
position is completely equal at this point as 42. Ree6 draws. Black can improve
at moves 40 & 41, but as I was expecting, Fritz is oblivious. It seems Kramnik
would have drawn in precisely this way if he had only played on. Tsk tsk.
