Agree With Snapper........
...you can never stop reading and learning. Once you get the count down pat, you can move on to learning anything and everything about casino gambling, attitude and on and on, ad infinitum . You would be surprized what you can learn in POKER magazines that apply to all sorts of A.P. including blackjack. A good example is Mike Caro's weekly columns.
Just remember, Tiger Woods is arguably the greatest golfer of the current crew, if not of all time, but even he still takes lessons on a regular basis. And all those pro-team athletes who are paid millions to play games we used to play in the school yard for free, constantly practice to improve their skills. Good luck and keep reading.
