What is it, that you need to learn?
In general, I'm pretty easy going when it comes to investigating the details of a puzzle. I consider chess to be a language, and I'm in the process of learning the words. Learning words is about coupling the pattern of a word to its meaning. When there is a clear pattern, and a clear meaning, and the frequency of occurrence is high enough, the word is worth learning. On the one hand this means that I reject complex Shakespearean constructions in archaic English, but on the other hand I try to make the most of simple constructions in plain English which show themselves when fiddling around. An example: White to move r2qr1k1/1p2bppp/p2p1n2/5N2/N1P1Pp2/1PB4R/P3Q1PP/6K1 w - - 1 21 A typical Vukovic situation. 4 attackers versus 3 defenders, can I sac a piece and get access to the black king before the black pieces spring into action? First the main line: 1.Nxg7 Kxg7 2.Qg4+ The black knight is pinned absolutely, so g4 is momentarily a save square. But why is 2.Qh5 not equally good?...
