4th Round (#2) - Judge: Paz Einat (Israel)


Genre: Orthodox direct twomovers (#2)

Theme:

Two sets (minimum) of themes are required. In each set there are at least two variations in which the Black weakening motifs (self-block, interference, unpin…) are the same, but the Black defensive motifs are different. This means that there must be a threat.

In the example both 1…b6 and 1…b5 are self-blocks but their defensive motifs are different (as mentioned below). Similarly, 1…f5 and 1…d3 are both unpins but their defensive motifs are different.

The two sets can be in one phase, as in the example, or in different phases (one in try and another in solution, or one in try 1 and another in try 2).

The judge encourages interesting executions of the theme, possibly with combination of other idea. Problems aiming to show straight forward multiplication will not necessarily be favored. These will be judged according to their artistic merit and any task-like achievement will be carefully assessed.



Example:

C. Mansfield
2nd Pr Ajedrez Espanol 1946
(= 9+7 )

#2
1.Bd6! thr. 2.Qc5#

Set 1:
1...b6 (direct guard) 2.Qd5# (selfblock)
1...b5 (interference) 2.Qc7# (selfblock)

Set 2:
1...f5 (flight provision by interference) 2.Se5# (unpin)
1...d3 (direct guard by line opening) 2.Se7# (unpin)


Closing date: November 10th, 2008

Prevod na srpski (Serbian translation):

4. kolo (#2) - Sudija: Paz Einat (Izrael)

Žanr: Ortodoksni direktni dvopotezi (#2)

Tema:

Traže se najmanje dva kompleta teme. U svakom kompletu postoje najmanje dve varijante u kojima su crni motivi slabljenja (samoblokada, interferencija, odvezivanje…) isti, ali crni odbrambeni motivi se razlikuju. Ovo znači da mora da postoji pretnja.

U primeru 1…b6 i 1…b5 su samoblokade, ali su, kao što niže navedeno, odbrambeni motivi razlikuju. Slično, 1… f5 i 1… f6 su odvezivanja, ali su im odbrambeni morivi drugačiji.

Dva kompleta mogu da se pojave u jednoj fazi, kao u primeru, ili u različitim fazama (jedan u varci a drugi u rešenju, ili jedan u prvoj a drugi u drugoj varci).

Sudija ohrabruje interesantne izvedbe teme, po mogućnosti kombinovane sa drugim idejama. Radovima sa pravolinijskom multiplikacijom neće obavezno biti davana prednost. Oni će biti ocenjivani na osnovu umetničkih merila i svaki rad koji nalikuje tasku biće pažljivo procenjen.

Primer:

C. Mansfield
2nd Pr Ajedrez Espanol 1946
(= 9+7 )
#2

1.Ld6! preti 2.Dc5#

Komplet 1:
1...b6 (direktna odbrana) 2.Dd5# (samoblokada)
1...b5 (interferencija) 2.Dc7# (samoblokada)

Komplet 2:
1...f5 (oslobađanje polja putem zatvaranjem linije) 2.Se5# (odvezivanje)
1...d3 (direktna odbrana otvaranjem linije) 2.Se7# (odvezivanje)
