I commented to another player that I got nothing from studying master games. He replied: :Neither do I."
One gains a little if the annotation includes mini-lessons. But terse comments are akin to a mathematician's "its obvious that ...". There are many celebrated moves I could never have found in a local game.
My Elo recently peaked at 1300. What level does one need before studying master games and having it be worth the time? That other player & I are both retired. Perhaps our ages are a factor.
