As I’m done solving easy puzzles (1000–1500), I decided to try some 1700 puzzles, but I’m finding it very hard to solve them as there are no obvious checks, captures and threats. Also, most of the times, the solution are about 5–7 moves. So, I figured that maybe a complete different approach is needed to solve these problems.

For example for this one, I don’t even know where to begin. I solved easier problems by finding all the checks, captures and threats, and the solution used to come within few seconds, but now things are not that easy. So is there a systematic approach?
