Having done a lot of mate in 1-hard (M1-h) lately, it becomes clear that it is important to have your chess atoms in top condition. Under chess atoms (the chess basics) I comprehend the four basic actions of Radovic:
Comparing mate in 1-easy (M1-e) to mate in 1-hard (M1-h).
I compared the M1-e with the M1-h. The main difference that I found is that with the M1-e the king is often at the rim of the board, while with M1-h the king is more often in the middle of the board, hence you have to check the aura of your pieces to see whether the cage around the king is complete.
After a few hundred M1-e I reached a speed of 12 mates (e) per minute, while after 6 days M1-h my maximum speed is 5 mates (h) per minute. So the difference in speed between M1-e and M1-h is mainly caused by slow aura vision (chess atom = restrict).
Conscious versus automatic learning.
There are two methods of learning you can try when you want to improve your speed at M1. One method is based on conscious learning, the other on unconscious automatic learning. With conscious learning, you visualize-II the solution for a while, in the hope that somehow you remember the visual characteristics of the position, so you will recognize the same type of position faster in the future. With automatic learning, you don't consciously look at the solution for a while, you just try work as fast as you can. My experiments with Troyis have proved that it is possible to improve automaticly and unconsciously. Just do a lot of exercises as fast as you can.
It seems that Thomasz and Aox tried to improve at M1-e the "Troyis-way". Just pushing the speed limits in an effort to become faster. This method seems subject to plateauing after a week or so of intensive training, just like Troyis. It has proven to be very difficult, if not impossible, to go beyond a certain threshold, despite a lot of working in the salt mines.
Improving with the automatic learning method.
The problem is, how do you select the appropriate positions? Scid has some possibilities to select positions based on their used material. Maybe that can be put to use.
Improving with the conscious learning method.
The method of conscious visualization-II has not been proven yet. This is the method I want to try first, since the other guys already have tried their hand with automatic training.
Either way, the journey will be very interesting.
