This puzzle was created with the idea of helping my chess students, whose ages range from 6 to 15, understand certain concepts about choosing a chess move. When solving this puzzle you frequently encounter situations where you have several choices. In chess we refer to these choices as Candidate Moves. The term Candidate Move was popularized by the Russian author Alexander Kotov in his book: Think Like a Grandmaster. The methods used for determining the right choice in this puzzle are similar to the methods used for determining the best candidate move in a chess position.
The original idea for this puzzle was to find a simple way to illustrate certain chess ideas. We realized very quickly how much fun it is to solve these puzzles. The development of this puzzle and its many embodiments soon took on a life of its own, which led us to the patent application process.

Recent Accomplishments: In 2009-2010 two of my chess students, ages 8 and 10, won first prize in the K-12 section of the St. Petersburg Scholastic Tournament. Two others, ages 9 and 12, earned second place in the K-12 section. All four have United States Chess Federation ratings of over 1000. This means they can no longer play in the Scholastic sections, but must play in the Open (adult) Chess Tournament.
Other Accolades: Placed first in the St. Petersburg Chess Open (2006 and 2007). Victory over Master Sunil Weeramantry in New York Action Tournament (1999). Sunil is author of Best Lessons of a Chess Coach, which deserves the highest recommendation. Lost a close game to GM Alexander Ivanov in the Vermont Spring Open (2002). Ivanov was once among the top ten in the world. In April 2011 one of the Home school chess teams that Allyn coaches won the First Place Team Trophy at the monthly St Petersburg Scholastic Chess Tournament.

I don't usually have a reason to post much here but today I do. My son's chess coach, who is one of the nicest and most brilliant people I have ever met, has invented a new 'game'. He has a website at www.mentagy.com. I have seen both the book and the board. For my therapy friends, the fine motor/cognitive component is really great for the little ones and the older ones.
