The November issue reported on the WCCC in Crete, where John Nunn won his third individual
World Solving title and Poland took the team gold. A number of obituaries included one for
Lu Citeroni, who was for many years a columnist in The Problemist and BCPS librarian.
Jeremy Morse presented his latest update of tasks and records, Yochanan Afek showed some
studies by composers born in 1910, and Browsing in the library covered Cyril Kipping’s 1932
collection The Chessmen Speak. Awards included Michael Lipton’s two-move informal
judgment for 2009 and the tourney for short proof games organised by Graham Lee and pupils
from Oakham School. In the Supplement David Shire examined the Java theme while
Michael Lipton reworked a half-pin cross-check matrix.

A four-fold example of the Rupp theme, involving simultaneous unpinning of a white and black
piece, appropriately by Rupp himself.
