And you have the game in your head or database, even it’s 1982.
I want that 😃. No serieous, it will be step nr 3:
1. Learn all the basic mating patterns and make notes for them (done); 2. Practice them daily on the easiest level possible (doing); 3. Add actual game positions to my notes per pattern as examples (plan).
First I learned all basic mating patterns and now I am doing puzzles per pattern on the easiest level possible.
Amazing how often I miss mate in one or mate in two as soon as it’s a bit off my beaten track.
So that is what pattern recognition is about. Very very useful.
