3 - **Ivan Denkovski, Gligor Denkovski** (Makedonia)

Champagne Tourney, Portoroz, 2002

Special HM

The thematic elements are the Zepler-Turton maneuvers with wKa1 and wRb1 on orthogonal line and wPe6 and bBf5 on diagonal line. But other elements of the rich solution (Ceriani-Frolkin,...) make the theme appear not so clear as in the prized problems.

6 - **Marek Kolcak** (Slovakia)

1st Com

Almost all the moves are thematic in this elementary but ingenious problem! A piece (Rook or Bishop) goes to free a piece that will take its place.
