Award of 33rd TT Chess Composition Microweb C 10.10.2013 - not awarded
(remarks to some non-awarded problems by Michal Dragoun,
selection of comparison problems added by Juraj Lörinc)
1 (Kf7-Ke4): The second bQ has technical use here. But even so the play is not balanced, 3.Sd5 serves as block,
3.S6d7 as unguard. Motivation for B2 is not absolutely analogous too.
2 (Kb1-Kg8): Use of promoted pieces without any sense: -a1, +bpa3 C+.
3 (Ka1-Ke5): Simple strategy. Twin looks interesting, but in fact is poor one.
7 (Kh7-Kb2), 26 (Kh2-Ka8): Multiple active sacrifice of black pieces allowing long walk of white King (and mate),
but problem PDB P1236906 without promoted force is quite close.
8 (Kg8-Kf4): Cycle of white moves, but not counting three white Knights, there is no special addition.
9 (Kg5-Kg1): Cyclic exchange of places of both four white and black pieces. I donīt know, if it is record
achievement, but even in such case no interplay disturbs me too much.
13 (Ka7-Kc5): Compare PDB P0548012 or older but cooked P0548034.
16 (Ke8-Kg5): There are dozens of problems with bQ standing on future black Grimshaw square. Usually the first
black moves are blocks or hideaways, but the same motivation as in 16 was already realized too (PDB P0580164)
and there is no special need for promoted force.
20 (Ke7-Ke5): Albino + interferences of black lines. However this combination in my point of view doesnīt justify
use of so much promoted pieces.
21 (Ke5-Kb1): Anticipated by PDB P0557306. Can be compared to P1003086 too.
24 (Kb3-Kd4): Compare PDB P1100971 and P0559589.
27 (Kd2-Kc8): Almost Oudot theme - but without promotions...
28 (Ke5-Ke3): Compare PDB P1074932 and especially P1266190.
30 (Ke4-Ka6): Two excelsiors and Knight promotions. Promoted Sb7 and Sb8 are only for miniature, with incarcerated
white King it is possible to use Bb7 and Qb8 as well.
31 (Kf2-Kc6): Threefold exact echo (Rd1 can be queen as well) with interference of black rooks for walk of wK
in all solutions. But number of repeated moves is really too high.
34 (Ka4-Kh2): Repetition of B2 is unacceptable. In addition bRg4 and two pawns can be used instead of bQ.
35 (Kc3-Ke5): Fourfold echo with twins, but with black King twice on the same square too. Can be compared to
36 (Ka1-Kf1), 49 (Kh7-Kf1): Mating pictures and pattern of three white Knights is known from PDB P0507444.
Added first move in 36 is not enough for distinction and promotions in 49 even less.
37 (Kg6-Kf3): Cyclic function exchange of white Knights, but black play is too simple and twins are poor.
41 (Ke4-Ke6): Compare PDB P0513200, P1002845.
42 (Kh2-Ke4): White cycle with blocks of initial black Kingīs square. It is well known and can be easily achieved
without promoted pieces and twins too.
44 (Kf8-Ke5): The content doesnīt justify technical promoted Queen, in my opinion.
45 (Kb3-Kf5): Whole play is well known (compare e.g. PDB P0528990, P0518520),
only motivation of the first white move can differ. However not original enough.
46 (Ke7-Ke5): Looks like a lighter version of 20 (without albino and with less promoted pieces, but with the
53 (Kg3-Ke4): Threefold echo, but again with repetition of moves Kg4 and Kg5.
55 (Kc4-Ke5): Two echo mates with line openings for black Rook, but for distinction I would like twinless setting.
57 (Kb4-Kf8): Three times the same black play (and only by King), white play is not very exciting too.
(If someone likes to use so called "constant" - the same play - and declare it as advantage, please donīt use
tourneys with me as judge.)
58 (Kf4-Kd2): Two black pieces from halfbattery capture white pawns on mating squares and as tempo moves
selfpin themselves. BQc1 is necessary for guard of mates by Ba5, but there are further problems for comparison:
PDB P0539486 (with two alternate pinlines) and P1276343 (unfortunately with bad white economy).
Some problems used promoted pieces to create apparently absolute exact chameleon echoes. I awarded some of
them, but usually it is only illusion. E.g. 5 (Kd3-Kb4) is sound with Bd6 and Re5 too, but then is clear
that blocks in single solutions are not exactly the same. In 10 (Kc1-Kd5) can be B on d6.
