Continuing my miniatures theme I did a Chessbase search for games which ended in a quick mate in less than 22 moves, and between players with 2600 ratings or more. I didn’t come up with much, and the opening was rather too complex to be of instructive value for the level of players who most benefit from miniatures.
Thus I would argue a great lack of relevance of modern Grandmaster games to beginners and post beginners. Of course is something that chess teachers have known all along, but not of course the chess as a spectator sport brigade.
Interestingly there were quite a few such games played at shorter time limits indicating that maybe David Bronstein was right in advocating fast time limits for top players. Of course the openings are still way too complex but at least some of the finales can be explained and understood.
