The Problemist, November 2012
Written by Michael McDowell   

The November issue contained a full report on events at the WCCC in Kobe. BCPS awards included helpmates in 2 for 2010 (judge Živko Janevski), helpmates in 3 for 2011 (judge Boris Shorokhov), moremovers for 2011 (judge Mikhail Marandyuk), and three-movers for 2010 (judge Don Smedley). Jeremy Morse presented his latest updates of tasks and records, while John Rice showed some problems by new composing Grandmasters. Browsing in the library covered the 1970 collection of Austrian problems, Problempalette. Paul Valois reviewed a number of books which were on sale at Kobe. In the Supplement Geoff Foster examined variations on a helpmate by Bror Larsson and Michael Lipton traced the development of a simple starflight matrix. David Shire's problem alphabet reached U for Unpin, and David also analysed a two-mover by Dombrovskis.
