Section C: More-movers

Judges: Austria, Germany, Netherlands, Russia, Sweden

Reserve Judge: Romania

Theme:

Direct-mates in 4 or more moves in which a white piece vacates square X to allow another white piece to occupy that same square X at least 2 moves later (i.e. White must wait at least one move after the vacation of square X before he occupies it by another piece). Pawn(s) may be used as the thematic piece(s).

Question 1:
"......... in which a white piece vacates square X to allow another white piece to occupy that same square ............." Is it required that the only purpose of the white piece vacating square X, is to allow an other white piece to occupy that square, or is it allowed to the vacating white piece to do also other things (f.i. capturing a black piece that guards the square where white finally mates)?

Answer:
Formally, any vacation, pure or impure in aim, is thematic. However, a convincing exposition of the theme seems to call for a pure, or at least a relatively pure execution. ["Relative purity" means that there are at least two ways to achieve a certain aim (e.g. "capturing a black piece that guards the square where white finally mates"), but only one succeeds because it vacates the thematic square for another white piece to occupy it later.]

Question 2:
In the only example, the second thematical white piece could not physically approach the vacated thematical field in less then 2 moves. Is the next example thematical? K.Haneman, 1sr Pr. "Skakbladet", 1953. W:Kf3,Rg1,Be3,Sg5 (4) Bl:Kh2, Ra8,Be5,Sc6,Sd5,Pd4,f4,h3 (8) 1.Ke4! (2.Sf3#) Sf6+ 2.Kf5 Se7+ 3. Ke6 Ra6+ 4.Kf7 and 5.Sf3#, etc. WS could come to the vacated field f3 in the second move, but is prevented to do so till the last move. Is this less thematical or nonthematical example?

Answer:
The immediate threat 2.Sf3 in the Hannemann example is not thematic because it uses the vacation of f3 on the next move. However, the arrival of Sg5 at f3 is thematic on any of the subsequent moves (moves 3,4,5).

Question 3:
Is it allowed for a black piece to enter the thematic square which was released by a white men for another white men? Is it even possible then capture this black piece by entering white men on this thematic square?

Answer:
Yes, this is allowed.

Question 4:
Is it possible to enter the thematic square by a white men in the mating move?

Answer:
Yes, it is allowed.
