Solving Contest 2006-06-18, Herakleion Attica, round1

The Fifth National Solving Contest in Greece, was held in the hospitable hall of the Cultural Poly-Centre of the Municipality of Herakleion Attica, (Sunday, June 18, 2006). It was organised by the Greek Chess Federation (ESO), with the care of the Chess Problems Committee and the support of the Chess Club [Epikinonia] and the Municipality of Herakleion.
Harry Fougiaxis was Arbiter – Judge, who was helped by G. Galanis, N. Mendrinos, D. Skyrianoglou.
There were two rounds, with thinking time 2 hours per round. The contestants were asked to solve a total of 12 problems, with 6 problems from six different categories per round, that is 2 two-movers, 2 three-movers, 2 more-movers (one four-mover and one five-mover), 2 studies (one stalemate and one win), 2 selfmate three-movers, 2 helpmates (one three-mover and one four-mover). As usually, first criterion is the correctness and completeness of the solution and second criterion is the time used by the solver.
The problems seemed to be easier than the previous years, but their solutions demanded knowledge, fantasy, and creativity from the solvers!
The final ranking (20 contestants) :
1) Prentos Kostas, 57,75 (237’), from Thessaloniki (Salonica), International Master in problems solving, was for fifth consecutive time Champion of Greece in problem solving.
2) Papastavropoulos Andreas, 47 (211’),
3) Mendrinos Nikos, 34,25 (240’),
4) Konidaris Panagiotis, 33,75 (240’),
5) Garoufalidis Ioannis, 27,75 (240’),
6) Manolas Emmanuel, 26,5 (240’).
In the first twelve places were also the solvers : Anemodouras Leokratis 24,75 , Sklavounos Panagis 24 , Skyrianoglou Dimitris 21 , Kostouros Al. 19,50 (he was present only in the second round), Mitsakis K.. 14 β., Barous Th.. 5 .
Together with the National Contest there was held a Solving contest for new solvers. It lasted two hours and contained six easier problems. The ranking : 1) Karaoulanis D. 24 , 2) Lymperopoulos F. (nine years old!) 12 , 3) Zissis M. 8 , 4) Zissis G. 5 , 5) Magiati Helen. 5 .
