Why learn techniques?
Most beginners hit a wall at medium difficulty. The reason is not effort - it is technique. Hard and expert puzzles are designed to require specific patterns: pointing pairs, X-Wings, hidden triples. Once you know what to look for, the same puzzles that felt impossible become a steady, satisfying rhythm. These guides are how you get there.
