|White to move|
It takes under 5 seconds to see that the black bishop is pinned to the king, and that there are 3 attackers and 3 defenders of the bishop. This information pops up immediately. Then it stops for a while. Only to see much later that you can remove easy two defenders at the cost of just one attacker.
This is a clear case of chess knowledge that pops up way too late.
If a piece is pinned, it is temporary immobile. The first question that should come up is: can I attack the bishop once more? Since that is not the case, the next question should be: can I get rid of the defenders?
But somehow this basic chess knowledge is not integrated in my system. So I dabble around with some trial and error moves, until after 50 seconds or so it pops up in the mind "look at the defenders!". It takes only a few seconds to find and assess the right moves and then solve the position. In essence I wasted 50 seconds.
If I want to solve these kind of problems faster, I need to get rid of those spilled 50 seconds. I must teach my mind to look for an extra attacker first, and when that leads to nothing, the mind should look directly at the defenders. Without further ado.
The motifs "function" and "geometry" are the most important ones for me and I concentrate on these. In this particular position "geometry" means the pin, and getting the rooks off the 7th rank one way or another. "function" means, who are the attackers, who is the target, who are the defenders. To just be aware of the functions of the pieces and their geometry is enough to let the suitable moves pop up. In this simple case.
