|Black to move|
8/4kp2/4p1p1/1pqb2P1/1p2nQ2/P6B/1PP5/1K1R4 b - - 1 1
On the white side
- The white king has little mobility due to lack of space.
- Black can set up a battery with Qc4, which is a duplo attack. A duplo attack is based on lack of time, as you know.
- b2 is immobile due to its double function, protecting both c3 and a3
- The black queen must keep an eye on the invasion square c7
- The black knight protects the invasion square f6
What I missed
The reason that I experienced difficulty with this position is twofold.
I missed the counter attack motif Rf1 Qxf7+.
I did notice the promotion motif, but I have not made an in-dept study of it just yet. So I mist an important aspect.
Often I don't look at counterattacks too much. As long as you don't waste any time, that usually isn't a problem. But since I didn't spot a continuation after the fast and obvious moves 1. ... Qc4 2.Kc1, I started to look at the promotion of the g-pawn and ended up with the slow move gxh6. Since it is too slow, white can start a counter attack with 2.Rf1 against the PoP (Point of Pressure) f7.
The point is that I hadn't identified another function of the white king: it has to stay in contact with the path to promotion. It must stay in contact with a2 and a1. Guarding the path to promotion, is a function specific to the promotion motif. this means that the move 2.Kc1 immediately should draw the attention to the path to promotion. Once I saw this clearly, the position started to look less complex and more simple. It's a miracle! I have found with no doubt the element I was looking for. And as expected, the knowledge is portable to other positions with the counter assault and the promotion motif.
