|Black to move|
This position is in the middle of a sequence belonging to the solution. Apparently I had forgotten my holistic approach, since it took me two (!) minutes to find the right move. What did I do in those two minutes? Good question! I was totally engaged in solving the problem of my overworked queen. I wanted to take the bishop on c6, but couldn't find a way to do so without loosing a rook. I must be stubborn, I guess, to try for two minutes something that is clearly impossible, if I had looked at it from a distance. But even at the moment my tunnel vision was broken, it took me some time to realize that Rxb7 simply wins a piece.

We gain proficiency (transfer knowledge into skill) in levels. We (usually) do not acquire complete mastery of each lower level prior to being introduced to the higher levels. Why not? Because we assume that we have proficiency when we really only have familiarity, and because of that "feeling" of familiarity, we try to move up one or more levels of abstraction before we are ready to do so; we lose interest in the "familiar" level because it no longer seems challenging. Because we "feel" that we have progressed beyond the "simplicity" of the familiar level (in spite of considerable contrary evidence, such as NOT "seeing" what is actually simple, like in the below-2200 puzzles on Chess Tempo), we convince ourselves that we are ready for more complicated stuff. Alas, it is the "simple" stuff that must be mastered before more advanced skills become ingrained into our subconscious as skill. WE KNOW THIS BUT WE IGNORE IT!
And that is exactly what this position is about. Imagine that this overlooking of trivial moves happens in 50% of the cases! The other 48% consisting of moves that are only a bit less trivial. Leaving 2% non trivial moves. The trivial moves are familiar, but don't jump you into the eye, which they should.
When I wrote about "thinking backwards" in 2007, I tried the same holistic approach as I do now. The difference is that I focussed on problems with a 2200 - 2400 rating. From the reasoning that I must exercise what I want to learn. But evidently, that was a bridge too far.
In the mean time, soaring around hasn't made clear yet how to solve this issue.
