GM Richard Pask has published the third Volume of his opening series "21st Century Checkers", a comprehensive guide to all 3-move openings.
This Volume covers all openings staring with 1. 10-14,
the so called "Denny"
The whole book, as the two Volumes published before, is available for download at Bob Newell`s recommended sitehttp://www.bobnewell.net/nucleus/checkers.php
