World Chess Composition Tournament of the FIDE

Organized by the German Chess Problem Federation “Die Schwalbe“.
Themes:
Section A: Two-movers
Theme proposed by Byron Zappas, Greece
Judge: Andrej Lobussow
At least two black defences change their defensive motives against thesame threat, with mates changed between at least one try and the solution. The following defensive motives are regarded as distinct: guard; pin; unpin; line-closing; line-opening; unblock; capture; check; anticritical move.
Section B: Three-movers
Theme proposed by Robin C. O. Matthews, Great BritainJudge: Robin C. O. Matthews
The same line is guarded by two black line-moving pieces (R+R or Q+B or Q+R). In at least two variations, self interferences occur on this line, either at Black’s first move or at Black’s second move
Section C: More-movers
Theme proposed by Uri Avner, Israel
Judge: Michail Marandjuk
In a problem of mate in 4 or more moves, a black line (actual, potential, or prospective) is opened without harmful effect after the respective black line-piece has been neutralized, or the ground has been prepared for its neutralization. The manner of neutralization is free (shut-off by either side, pin, withdrawal, annihilation, etc).
Section D: Endgame Studies
Theme proposed by Anatoli Kusnezow, Russia
Judge: Welimir Kalandadze
In order to gain or lose a tempo, White refuses to capture a piece (not a pawn). Win or draw.
Section E: Helpmates
Theme proposed by Harry Fougiaxis, Greece
Judge: Harry Fougiaxis
In each of at least two phases, a white/black manouvre fails through the actual, potential, or prospective closure of a white line by black and/or black line by White. The thematic line(s) may exist in the diagram position or be created during the play. Helpmates in 2 are required; no zeroposition.
Section F: Selfmates
Theme proposed by Hartmut Laue, Germany
Judge: Friedrich Chlubna
In a selfmate in 3 or 4 moves a black move has a defensive motive which White exploits to his own advantage.
Section G: Fairies
Theme proposed by Theodor Tauber, Israel
Judge: Michel Caillaud
Vaulting King (definition): An orthodox king which, when in check, moves like the checking unit(s). Direct-mate two-movers are required, with at least one vaulting King. Orthodox units, Grasshoppers and Nightriders may be used, but no other fairy units.
