Notes 19jun2025
The limitations of the lichess "viewer" introduces some repetition and silliness such as "1/2-1/2 wins."
The examples are formatted with instruction in mind; along with the viewer limitations,
historical accuracy suffers as a consequence.
For example, Myagmarsuren resigns after 31. Qxh7+, Chigorin misses the combination,
joe8813 doesn't take the rook.
