This is my analysis of today's chessgames.com Game of The Day between GM Anthony Miles and IM Arkhipov. This game clearly demonstrates how a GM's positional understanding of chess OTB is superior of that of Fritz, or that of the IM in this game.
The critical inaccuracies are 8...a4 and especially 12...0-0, which loses. Enjoy!
