I guess you could say that the person who has won the most money is the best? Or the person with most wsop
bracelets? Or maybe the player with most tourney wins?
It really is a unmeasurable thing and thats why I love watching poker. Gus Hansen isnt the best player in the world but I love watching him play so maybe hes the best for me I dont know. To your question I guess there is a system you can use to find the best player but it would be different for each person for example I dont think many people here think Helmuth is the greatest player.
And then you have to think wider than holdem, who playes every game to a high standard? Intresting question though very subjective.
