The fifth and concluding volume of Richard Pask's Landmark "Logical Checkers" series will be available at The Checker Maven website at 00:02 HST on 2020 Sep 19, just a few hours from the posting of this message. (Earlier download problems have been resolved.)
Volume 5, titled "Three Move Expert: Unbalanced Ballots" features lots of new material including an extensive study of bridge positions. The book runs over 300 pages with many diagrams.
Be sure to download your copy right away. As always, Mr. Pask has generously provided this book to the checker playing community free of charge.
A combined, five volumes in one omnibus edition of the complete series, both in electronic and print format, will soon be in the works and will be offered through my small publishing house, Avi Gobbler Publishing of Honolulu. It will run over 800 pages with over 1,000 diagrams and will take many months to design, typeset, produce and publish. Look for it in the latter part of 2021. The electronic version will be free. The print edition will be priced as low as possible to still allow for cost recovery and extended channel distribution.
Thank you once again, Grandmaster Pask!
