Since Professor Johnson says there are no secrets and that everything one needs to know is at Dr. Dave's website let's have a little thought experiment.
Two rank beginners are each locked in separate rooms for a month. Each has a pool table and cues of exactly the same specifications.
The first player, we will call him Public Domain or PD for short, has access to the internet and can receive all instruction he gets ONLY from the internet. He can read articles, watch YouTube, do video chats etc...
The second player is locked in with 3 world champions and no access to the internet. We will call this player The Rookie or Rook.
At the end of exactly 30 days PD and the Rook match up on TAR playing a round robin of 10 Ball, One Pocket, and Banks for $100,000.
Who do you want to bet on?
