Award of 15th TT Chess Composition Microweb - orthodox section - C 30.9.2004
First, I would like to thank Juraj Lörinc for inviting me as a judge of this
tourney. I was curious after the announcement, what can be done in orthodox helpmates
in five solutions. I knew some splendid examples (from the HX2 field e. g. very
early five-fold switchback problem of B. Lindgren, PDB 500059, very famous A.
Molnar´s five-fold Zilahi, PDB 521048 with version under Nr. 539272, twinless five-fold
cycle of white moves of M. Herzberg, PDB 521633, to quote only some of them).
But thinking about common possibilities, I was a little bit incredulous. With
five solutions is sure possible to incorporate some strategic elements into the
problem content, but not very deep ones. Odd number of solutions is not very pleasant
for realization of some orthogonal-diagonal analogy. So - maybe something in HOTF form
with one extra solution? (Finally was not presented between the problems.) Or some
geometrical themes with one added phase? (This case was sent.) But in general
in my opinion the announced "theme" was quite hard and result is not so successful
as in other Microweb thematic tourneys, at least in the orthodox section.
For judgement I received 15 anonymized problems. My ranking is as follows:
Praha, 28. 10. 2004
Next two problems show known ideas in (I hope) partly new mechanisms:
Here are my notes to not awarded problems:
H2 (Ke8 - Ka8)
Five different Rook mates on the same line with line opening in B2 is shown in
problem of B. Lyris + N. Siotis (PDB 502047) where unpin in B1 is more interesting.
Even more similar is J. Csak´s PDB 565896 with the same motivation in the first
move and line-opening mostly together with line-closing in B2.
H3 (Kf8 - Kh8)
Idea (with unhappy idle wB) was shown in H. Moser´s PDB 505058. And moreover H3 has
illegal setting... (BTW: in the meantime task with seven mates on the same
line was presented: V. Bunka + V. Kotesovec, Šachová skladba 85/2004.)
H4 (Kf7 - Kd4)
Five different blocks with some additional elements presented in solution pairs:
Somov mates after 1.e5 and 1.Sc2, battery mates in 1.Qd6 and 1.Be2 solutions.
But whole has no deeper idea, blocks by five different pieces were already
shown even on the same square (I consider problem of R. Vieira, PDB 530479 for the best one).
H5 (Ka4 - Ke4)
Some geometrical effects in the play, but no other interesting aspects in the solutions.
H9 (Kd4 - Kb6)
Five different King´s moves from the battery line are present e. g. in
J. C. van Gool´s PDB 502995. Here five various captures of bR are added,
but white economy is too poor for my taste (as in comparison problem too...).
A little bit better economy was achieved in problems with six solutions
(PDB 502981, 503985, 503988).
H13 (Kh2 - Ke6)
Five model mates including two echos. But only cumulation of model mates is not
my taste and moreover a lot of moves is repeated here
(especially bad in the case of 2...Bxe4).
H14 (Kc1 - Kd6)
Again five model mates, but without connecting link between single solutions.
H15 (Kb8 - Ke2)
Five echo mates by promoted white Queens. But I am not convinced by time
economy of this problem: two moves of all white pawns are boring and partly
similar settings were realized in HX2 form too by J. Mintz (PDB 541793) and
S. N. Tkachenko (PDB 538782) where black pawns have a role of the chessboard border.
