After watching back my video I would like to add an improvement.
It seems silly to deem white’s 19th move Qd2 as dubious, after all the ensuing endgame with queen versus two rooks is a draw most likely, so that is no worse for White than the line I gave after 19.Rf5. Somehow I thought that Black had chances with the two rooks against the queen – which remained a sticky thought in my mind – until I noticed that White can win the pawn on g7.
Also later today I learned that the move 19.Qd2 had already been discovered by Kasparov back in 1999! Apparently Kramnik was facing something really new and it remains to be revealed if he missed 22…Rc8(!) as pointed out in the video and that he felt forced to play 19…Ng6?, or that he underestimated White’s chances after 19…Ng6?
Anyway, here is the video.
