Award of 20th TT Spisska Borovicka C 5.9.2008

This is the award by Peter Gvozdják of TT that was announced on CCM too.

For the jubilee 20th tourney I have chosen too difficult theme. Even the experts are not of the very same opinion what is a dual avoidance. Then, probably the example was not completely clear, too. The result was I have received only two problems of good quality which I decided to award. (For the next year I promise to give something much simpler.)

Commendations ex aequo:

Honourable Mention: (01) (Quah)
Ukraininan cycle with dual avoidance in variation mates.

Prize: (05) (Lörinc)
Shedey cycle with dual avoidance in solution only. Motivation is interesting, but the fairy means are quite different.
