Chess Solving Contest 15-03-2008, ESSKEDYM Ptolemaida

FIDE Master Spyros Ilandzis has sent to us the following correspondence.

The 9th Championship of Central-West Macedonia (translators's note: this is a part of Greece, not F.Y.R.O.M.) was held in city Ptolemaida, and lasted four days March 13-16. It was organized by the Union of Chess Clubs in Central-West Macedonia (Enossi Skakistikon Syllogon Kentro-Dytikis Macedonias, E.S.S.KE.DY.M.) together with the three chess clubs of the city, S.O.Ptolemaidas ”Ptolemaios", S.A.P. ”Skakistakos”, and ”Dourios Hippos”. (See more here in Greek).

In parallel with the OTB chess championship, there were organized various happenings, and among them the 2nd Chess Solving Contest ESSKEDYM-2008, with twenty participants! Before that, Spyros Ilantzis gave an introductory speech about Chess Compositions, presenting various themes, with an audience of more than thirty persons (many of them were children)!

In 2nd-SC-ESSKEDYM-2008 six problems were given, (five direct-mates and a study), and with 5 grades per problem we have maximum grades : 30. The time limit was set to one hour and thirty minutes. The first ten solvers were the following :
