What do you mean .. the best games or the annotators ?
Almost anything annotated by Timman is very good. Also of course Bronstein Zurich 1954.
The most funny game annotated is by Donner in his briliant book "The King". He wrote a beautifull writeup of the game Donner - Velimirovic called pretty little thing with very nice sentences like (translated from Dutch)
"When I was younger i considered the Benoni as completly inferior and winning should be just a matter of technique combined with preseverence. Now I know better more than once i have ben kicked of the board by this aggresive opening to know that chess is far to difficult for me and it would be wiser for me to play easier positions"
I would think it interesting to make a list of the very best annotated grandmaster games for learning. If anyone has one or two candidate games post it or them here. Later, maybe we can make a list of the top 20?
