Steve, I do like your query. So now, let's ask again:

Assuming he had a bankroll and was comfortable with the stakes. How would a great 300-600 player be overmatched in a 1-2K game? Are the players really that superior?

What does a 1-2K player have that a 3/6 doesn't? Is it simply a pure talent issue? No matter how hard Kerry Collins works, he'll never be Brett Favre.

I really think those games are about individual match-ups and knowing who to attack. If you took a table of 10 great players, the 10th best player may have the best player's number, while the best player may destroy the top 3 players rountinely, but knows to avoid player 10. And player 5 does well against player 7, but struggles against player 8, and so on.
