The Amethyst Academy
Study Leonard's 15 principles and the tactics that power them — checks, captures, skewers, pins, discovered attacks, and mate-in-1s — plus opening guides for the Caro-Kann, Sicilian, Italian, and London System.

Puzzle of the Week
What would you do here, as Black?
A knight on f7 forks the king and queen — but the position is full of counter-threats. Train your eye for checks, captures, and threats, and the right move reveals itself. This is the kind of thinking the 15 principles are built to sharpen.
Lessons coming soon
