I really loved that, What I notice is he doesn't make the game more then it is. He opens the balls and runs them. Not a lot of bumping and picking. I used to watch and even played Balsis a few times. John plays exactly like Balsis. He doesn't over annualize everything. Balsis told me to open the balls and get them off the table however worked for me. They are all worth 1 point no matter how I got them off. Quite different then how say Crane played with all his examining the balls and bumping and picking around the rack seeming afraid to have a ball go up the table.
I am not saying someone who likes straight pool should play like John, but this video is worth studying. Obviously he is playing small patterns and thinks very quickly, but he is also changing constantly as the rack develops always keeping escape balls if the cue ball doesn't fall exactly right. his game is very fluid in the way he moves from one small pattern to another clearing the table. Great video I really enjoyed it. It is a lesson in as Danny DiLiberto always said, "Good pool is just doing simple things consistently".
John makes it look easy, maybe because pool is a bit easier them many believe if you give yourself a chance and let it happen and don't over think everything.
Just my opinion.
