A Word About Methodology:
Chess Assistant 11 is used to generate grist for the puzzle mill at this website. I use Rybka4 to analyse winning positions and eliminate any puzzle with more than one winning move. When I started solving chess puzzles, my rating rose 400 rating points. Unfortunately, many puzzle books present puzzles by tactics, ie knight forks, skewers, etc. Imo, this simply tells the student what to look for.
The Author (Christchurch, NZ)
Mongoose has posted a review of my book on gambits: The Gambit Files: Tactical Themes to Sharpen your Play. Chapters include: Ruy Lopez: Gajewski Gambit, Scotch Gambit, Cochrane Gambit, Rosentreter Gambit, Wing Gambit, Grand Prix Attack: Tal Gambit, French Advance: Milner-Barry Attack, Caro-Kann: Fantasy Gambit, Scandinavian: Portuguese Variation, Winawer Countergambit, Geller Gambit, Albin Countergambit, Blumenfeld Gambit, Queen's Indian Polugaevsky Variation & Lisitsin Gambit. It contains literally hundreds of insights gained from reviewing thousands of games which highlight recurring themes and tactics in these openings. Where I might not want to post puzzles to this website that seem similar to each other, in The Gambit Files, it's instructive to accentuate the similarities and why they occur and reoccur in a particular gambit. Ten to forty puzzles illustrate each chapter's gambit. Studying openings from characteristic combinations creates a very fruitful and memorable learning experience. I'm nearing completion on a series of ebooks on chess openings for Mongoose Press. The first volume is on the Alapin Sicilian and is due out around the end of January.
I've been creating the puzzle column for the Postal Chess SIG for Mensa over the last ten years and sending out puzzles to subscribers every two weeks about that long too. For about a dozen years, I taught a chess class in a Washington, DC junior high school. For several years I took weekly lessons from the Virginia State Champion, Steve Greanias. I've completed an extensive series of courses on collections development taught by Dr John Sherrod, former Director of the National Agricultural Library in Washington, DC. I hunt for prime numbers at the U Cal/Berkeley PrimeGrid Project. My biggest find is 807x2^696608+1, a 209,703 digit prime and the 1,048th largest in the books when it was found.
