Gianni Donati 50th Jubilee Tourney

Awarded Problems

I could not have imagined a more delightful set of entries to this tourney. My thanks to Dan Meinking for administering the tourney and for keeping after me to make the difficult choices required by the high level of the competition. Thanks also to Michel Caillaud, Noam Elkies, Ryan McCracken and Kostas Prentos, who woodshedded the 94 entries (after Dan had given them his initial review) and cooked 13 of them, leaving 81 problems to judge. (I believe Dan notified the authors of the cooks; many attempted ambitious schemes which I hope can be corrected and published.)

The entries exhibited numerous motivations for a promotee to leave its promotion square and return, which was the theme of this tourney: these included capture of an opposing unit (most often a pawn or a blocked bishop); clearance; screening of one king or the other against check; provision of a safe path for the opposing king; and tempo. In general, games in which capture-and-return was the principal motivation were less successful than others, though this was not uniformly the case. The theme lent itself to the production of extra-set pieces in the diagram, but happily many composers managed against all odds to avoid this even while showing complex ideas.

I am comfortable with the selection of nine problems for prizes, though I am not sure I got the ranking among them right. They are all splendid problems and achieve their aims elegantly, without evidence of the difficulty which composing them surely entailed. I selected fifteen problems for Honorable Mention and twenty-two for Commendations. While this honors slightly over 50% of the entries - which may seem a high proportion - the truth is I wrestled with myself to cut the list down. There were many fine problems that do not appear here, and they surely would have had the overall level of composition not been so high.

I thank everyone who contributed to make this tourney a great success and a wonderful birthday present!
