Who is better Paul Morphy or Magnus Carlsen

You cannot draw conclusions from one game. What you can draw conclusions from is match against second best player in the world. Morphy defeated Anderssen 8:3. Carlsen - Caruana was a tie.

Paul Carlsen is best.

I checked with an engine, and it says Bobby Fischer was best.

Carlsen is only second, Kasparov third.

Bobby Fischer was best.

Phisher, I mean, not Fischer.

Stockfish at 4000 elos is best.

morphy is better just watch the oprea game

Magnus Carlsen

Despite all the chess theory knowledge and science . All you need is a talented kid with a good coach and you wind up with a 2790 16 year old.

Murphy is dead. So there's that.

Comparing people of different eras is misleading at best. Who's better? Roger Staubach or Patrick Mahomes? The latter was playing during a very different offensive-friendly league but clearly has better stats.
