Rehab of trial and error
That is why I want to rehabilitate trial and error. Since that is the way system I works best. If you need to guide system I by system II, you add slowness to the equation. Since system II is notoriously slow.
When trial and error fails
trial and error fails in practice, for different reasons:
- repeating the same moves and lines over and over again
- entering a tunnel and continuing ad infinitum
The actions of systems II that can be safely incorporated
The actions of system II involve the following:
- Stopping system I when it is repeating itself
- Stopping system I when it is working in a tunnel with no end
The two actions of system II that don't require time, do require attention.
Where system II is, there is attention. Where attention is, there is the power to discriminate. Where attention is, there is intelligence.
System I is semi intelligent
System I is only semi intelligent. It emulates intelligence. It brings you safely to your office. Even when you didn't intend to go there. Without the attention of system II, it can do silly things in an intelligent looking way. System I can work on autopilot. But it can't learn on autopilot. It continues to make the same mistakes over and over again. We even have a name for this type of "training". We call it the salt mines of Krakau.
It is relative easy to learn to see the material balance in a glance.
It is relative easy to learn to see whether a position is about mate, promotion or gaining wood in a glance.
It is relative easy to learn to see the points of pressure in a glance.
It is relative easy to learn to see the lines of attack in a glance.
It is relative easy to learn to see the function of the pieces in a glance.
But it is not easy at all to remember to look at all five issues above without thinking. And with thinking you add time consumption, mental resource consumption and energy consumption to the equation.
