Have a look at diagram 1.
White to play.
Since I had no clue, I started with trial and error.
I tried the following moves in my minds eye:
None of these tries triggered something in me.
Until I tried 1. Nf5 exf5
At that moment I saw the double function of e6 (protecting the bishop and defending f5) and all pieces of the puzzle felt together. The knightfork, Qg7#, the exchange sacrifice on d5).
It is clear I used an enormous amount of time.
Maybe the thought process that Mousetrapper is developing would have helped me here.
What is remarkable is that the first move of the solution (1. Rxd5) didn't trigger anything in me. The basic pattern of the combination was only revealed to me by imagining 1. Nf5 exf5, which is actually the SECOND move of the combination.
This indicates that you first have to see (as a pattern, in the minds eye) the end position and then work your way back. Which is called calculation.
I have to be more precise. It was not exactly the END position what was recognized.
It was actually the position of diagram 2
Of course this sort postions are not stored in LTM exactly as this diagram. With every pawn and all. Only the main properties are stored and recognized:
- The knightfork
- The mate with Qg7
- The pin along the g-file
- The black Queen can't prevent the mate without sacrificing herself
How can I make that my LTM releases diagram 2 at the moment I see diagram 1.
Or: how can I store diagram 2 in LTM in a better retrievable way.
When you have a close look at diagram 1, you see that the rating of the problem is 1727.
In other words, all 1727 rated players at CTS will solve this problem in 10 seconds at average. What do I have to do so that I can do the same?
I'm experimenting with different methods. Whithout reaching a conclusion sofar.
