@drmrboss, you’re right. That’s why I think it’s nonsense to compare…
A 2200 player @ chess.com playing only 1200 players, will give a lot of punches…but will gain little to none ratingpoints…and for that probably will never reach the magical 2700 mark.
One reason that amateurs are less impressed by modern players is that the general level of tournament play has improved across the board, especially defensive technique.
Modern masters seldom produce anything comparable to Morphy's Opera game, not because they lack Morphy's talent, but simply because their opponents don't allow that sort of brilliancy nowadays. The standard of modern defensive play doesn't allow that sort of smashing win anymore.
In order to produce a brilliancy, it isn't enough to play well. Your opponent must play poorly.

The opponent skill in opera house was like 1200-1300( He didn't know or didn't follow principle in developing basic pieces).
If 2700/2800 GM vs 1300 play today, you will see similar one sided punch.
