Award Helpmate twomovers 1998
In 1998, there were 88 problems in the Probleemblad helpmate column; among them, two had been published in other magazines before and were thus not eligible for distinctions.
I would like to thank Peter van den Heuvel for asking me to act as ajudge in this renowned magazine and Hans Gruber for helping me to find anticipations and problems that offer interesting comparison. Judging an informal helpmate tourney is a lot about comparing the entries to what has been done before, maybe more so than in other genres, as so many helpmate problems have been published recently that it's almost always possible to find something. As it has become typical for helpmate informal tourneys, 1 got a great deal of assistance from the solvers, criticising constructions and providing versions and problems for comparison; their comments explain why 1 did not include several interesting problems in the award.
In addition, the following problems have been excluded because of anticipations, better predecessors or thematical flaws:
I found the level ofthe remaining problems quite high, which explains the rather high percentage of distinctions.
- H054 by Jevgeni Markov is anticipated by Matti Myllyniemi (diagram A) ;
- H073 by Toma Garai: cf. Jean-Marc Loustau (diagram B) ;
- H080 by Tode Ilievski: cf. Attila Benedek (diagram C) with the additional paradox that the originally pinned white piece gives the mate;
- H088 by Nikolai Nagnibida: I don't consider the problem given in PB 1998-5, p. 191 to be an anticipation since the first black moves of H088 add strategy. I didn't award it, though, because of its overly heavy construction and its logical impurity: if the black Rook and black Bishop moved to d3 from the side (c2/f1), we'd have dual-avoiding blocks instead of blocks that happen to interfere. See my article in idee &form 62/1999 for a longer discussion;
- H100 by Gennadi Tsjumakov: cf. Frank Fiedler (diagram D) ;
- H129 by Aleksandr Pankratjev & Dieter Muller: cf. Zoltan Laborczi (diagram E) .

Nice functional change ofwhite Rook and Bishop both in the set play and the solution (Zilahi). 1 also like that the selection of the black pieces capturing at c2 and e7 is based on negative effects of the Knight moves. All this is added value to Janos Csak (diagram F) , and compensates well for the not so pretty position.

Some time ago, 1 awarded the similar looking Gabor Cseh (diagram G) the Ist prize. The play in H064 may look less ambitious, but the pin-mates are more subtle than what we find in Gabor's problem.

Usage of white battery pieces in newly created batteries as required in the WCCT. Much to my surprise, there is only one WCCT entry (Manne Persson, 12th rank) with this combination and a black half-pin; H099 has more interesting black play.

The author has created several examples of this cycle, but (to my knowledge) not so far with the entire play on a direct third-battery. One could argue that Miroslav Stosic (diagram H) contains double the content of H111 (with much less effort!), but the avoidance of the other variation in each solution is the essence of H111.
I would have preferred quiet first white moves, but 1 don't know if they are possible

H125 is thematically denser than the problems printed for comparison with its solution (PB 99-2, p.57): there are only thematical white pieces so that we have a Zilahi. 1 don''t give a prize to H125 because Arefjev's sacrifices are more subtle.

From a thematical point of view, this problem may not be on the level of its neighbours in this award. But 1 like such neat realisations where there isn't a single non-thematic piece. There is a serious danger of anticipation, but 1 haven't found an example with anticipatory unpins.

1 have always been fascinated by problems where a white line piece has to be replaced by another one. Here we have an example where both replacements occur on the same line, which allows the replaced piece not to be the Queen. 1 didn't take into consideration the fact that the thematic line is masked, which in theory could make the solver's task a little bit more difficult. In Hl 12, the masking is artificial since the white Bishop could as well stand on h5 in the diagram position, which, by the way, looks heavy, but 1 can't find any obvious draw-backs in the construction.

Interferences of the black Bishop that cause the black King to be 'pseudo-unpinned'. In strategical two-movers 1ike this, I think it's important for the thematical moves to be purely motivated. But, as pointed out by a solver, in H110(a), the black Rook has two (or maybe one and a half...) reasons for interfering with the Bishop al (check and control of f6).

If l hadn't known of the Problemkiste problem provided by a solver in PB 1998-4 p. 148, 1 would have awarded H068 higher. 1 don't consider it to be an anticipation, but where we 'merely' have King moves in H068, there is additional strategy (black anticipatory self-pin) in Problemkiste.

The Java theme in helpmate form; 1 must confess that 1 have absolutely no idea if there are earlier realisations. This one is not too much to my taste, partially because the locked out white Queen has to be brought into play which made the solutions rather obvious.

There are many two-phase problems with anticipatory self-pins, but a lot of them don't show double-pin mates, of course. Daniel de Irezabal is interesting to compare (diagram I) ; I prefer H066 because it substitutes exchanged functions of the black pieces for the twinning mechanism.

Two white Knight-wheels seem to be new, and they are realised with optimal white economy here. The author seems to have been interested in the fact that all the first moves are executed by one Knight and all the mating moves by the other. Luckily, he didn't have to pay for this with additional black material; every black piece contributes to at least one mate.

Tempo captures with exchange off functions (Zilahi); the interceptions in Black's second move are well integrated. Everything except the Zilahi has been shown in the equally crowded bemd ellinghoven, feenschach 1991 (diagram J) , where strategical means are employed to prevent the black Knights from losing the tempo.

Nice differentiation of the black play in a heavy setting. It's obviously very hard to show something outstanding in this context after Franz Pachl's marvellous problem (diagram K) .

Interesting play, but I don't understand why the author chose to pin the white Rook and Bishop in the diagram position. The author has shown the same strategy in Mat-Pat 1994 (diagram L) , but here, the play is much more obvious because of the white Pawns on the seventh line.

What should I add to the discussion in PB 1999-2 p. 57, apart from the fact that this would have got a prize if both first black moves were pure tempo moves?
