The Problemist, November 2005
Written by Michael McDowell   

The November issue contained various reports on events at the 48th World Congress of Chess Composition, held at Eretria, Greece, where, in the solving World Championship Great Britain won the team title, with Jonathan Mestel and John Nunn taking silver and bronze respectively in the individual event. The duo were also successful in the Open solving event, Nunn winning gold and Mestel silver. Geoff Foster and Bob Meadley presented an article on Australian composer Arthur Mosely and his column in the Brisbane Courier, while In the Library reviewed the famous mid-19th century work Collection des plus beaux problèmes d’échecs by Aaron Alexandre.

In the Supplement Juraj Lörinc examined the fairy piece known as the Lion, John Rice annotated a selection of the work of the late Alex Casa, and Steve Giddins presented some studies with which to torment your team-mates.

Mate in 5 with the pawn, without capturing the rook

Not many problems from the early 19th century are still worth a diagram today, but this conditional, with its superb second move, is one.

Mate in 2

A problem showing selfblocks with dual avoidance, known as Stocchi blocks. In the diagram, if a dummy piece blocked d4, White would have three mates, 2.Bd5, 2.Bd3 and 2.Qg2. Various effects contained in each black capture ensure that only one mate works each time. After the key move the arrival of a dummy piece on d4 would allow three new mates, 2.Sxf6, 2.Sxc3 and 2.Qf3, and again these are accurately separated.

Set play:
1…Sbxd4 2.Bd5
1…Scxd4 2.Bd3
1…Qxd4 2.Qg2

1.Sd5 (>2.Qh4)
1…Sbxd4 2.Sxf6
1…Scxd4 2.Sc3
1…Qxd4 2.Qf3
