I'm interested to know the trainers who put a strong emphasis on system 2. Don't they recommend a heamthy dose of system 1 as well ?
Some quotes :
Botvinnik : “Yes, I have played a blitz game once. It was on a train, in 1929.”
Fischer : "Blitz chess kills your ideas."
Short : "I play way too much blitz chess. It rots the brain just as surely as alcohol."
Dvoretsky : "In this book (Analytical Manual), (..)you will be asked to solve a series of consequent tasks (...) This is a training method I worked hard and began using successfully many years ago. Set yourself a certain time control (1 hour, for example) and try to find one move after another(...).
Open any Dvoretsky's or Kotov's book and you will see they always applies system 2.
You're comparing apples and oranges LePontMirabeau. No one is saying study amateur games with lots of mistakes very rapidly and ingrain the patterns. You have explained why bullet is so bad for anything but titled players. You just end up repeating your mistakes until they become ingrained habits. The idea of watching master games rapidly is just the opposite: watch master level patterns of play and absorb them. I'll use that method if I'm trying to learn a new opening for instance by filtering games from a database and just watching them play out. Of course I study the theory as well, but there's a place for this rapid training in any chess player's curriculum.
