73 compositions participated in this tourney (29 twomovers, 26 threemovers and 18 moremovers). The average quality, even if not particularly high, was satisfactory. The prizewinners were picked up easily. I tried to provide comments to most of the participating problems, as almost none was given in the solutions.

Anticipations or compositions of limited originality :

43 is anticipated by Avner Bar-Nir, Shahmat 1977 (PDB P0526387, WID 237938), while 46 by Jorge M. Kapros, MH idee & form-10 JT 1994-96 (WID 202985).

47, 51, 53 and 57 have been already published as 5303 diagrammes 149 April 2004 (WID 193186), 1573 Orbit 27 July 2005 (WID 206757), 4422 Phénix 124 December 2003 (WID 188445) and 5174 diagrammes 147 October 2003 (WID 177873) respectively.

49 is substantially anticipated by Fadil Abdurahmanović, Magyar Sakkélet 1979 (PDB P0559869, WID 59129), even if the composer’s trick to use a white pawn for one of the mates in order to get models is smart and adds variety.

60 is anticipated by Garen Yacoubian, 2° Prix The Problemist 1973-74 (615 FIDE Album 1974-76, WID 23242), Viktor Chepizhny, Kudesnik 2004 (WID 245445) and Aleksandr Pankratiev & Vadim Vinokurov, 2°-3° Prix Rabochy Kraï 2005 (WID 260599).

67 is anticipated by Julius Bebesi, Magyar Sakkvilág 1936 (PDB P0565066, WID 7011), Henry Tanner, MH Ideal-Mate Review 1994 (PDB P0501158, WID 7013) and Luigi Vitale, Thema Danicum 1999 (PDB P0577776, WID 209034).

145 shows anticipatory self-pins of three black pieces along the same line, which have already been blended with a cycle of white moves in Chris. Feather, 2° MH The British Chess Magazine 1972 (PDB P0504456, WID 119248).

152 is anticipated by Viktor Bene, 5° MH Probleemblad 1998 (PDB P0576708, WID 116387). 210 shows cyclic Zilahi with prolonged Y-flights, a combination that has already been achieved in miniature and in 3 solutions form (yet, at the cost of a repeated white move) by Zvonimir Hernitz, 1° Prix 13° TT Problem-Echo 1995-96 (E34 Album FIDE 1995-97, WID 9774).

215 is actually a version of the same composer’s 6° MH Problem-Forum 2005 (quoted together with the solution) showing interferences on two black lines and having a visually more attractive setup, alas at the cost of twinning. By the way, Jones’s composition of 2005 fully anticipates a later problem by Abdelaziz Onkoud in Chess Leopolis 2010 (WID 418190).

223 is anticipated by Norbert Geissler, feenschach 1993 (PDB P0556338, WID 3765), which furthermore avoids the unnecessary black pawn.

Constructional defects :

There is idle white material in the set line of 52, and repeated moves in 56 and 150. 146 is strangely to our days cooked. The awkward capture R×h1 in 159 should have been avoided. Thin content or not of any particular interest :

42, 44 (Chumakov theme with ideal mates, but too dry to my taste), 58 (twins (c) and (d) are symmetric), 59 (rather simple Zilahi), 140 (self-pin hideaways with unbalanced B1 moves), 142, 143, 144 (minimalistic Zilahi with pawns), 149 (just a scheme), 151 (ideal mates without any strategy), 161 (too many repetitions), 162 (ordinary single-liner), 212 (very familiar reciprocal black self-unpins), 214 (merely a pair of mutual captures), 216 (only two black switchbacks packed with a lot of ordinary moves), 221, 222, 224.

Thematically not profound enough to be included in the award :

 64 (the WCCT-8 theme with two pairs of analogous solutions in HOTF style ; unfortunately the twinning is excessive),
 66 (two switchbacks of the WB, but unbalanced solutions),
 68 (a puzzle for solvers, but the quoted “try” is not so convincing ; it would have been more interesting if it could not work because of lack of a tempo, for instance),
 69 (tricky solving, but not to my taste),
 70 (nice and probably novel hiding manoeuvre by the WK that involves a tempo, but there are many earlier problems showing even an AUW),
 141 (charming and well-constructed, yet the W1 moves are commonplace),
 153 (black sacrifices for gate-openings, but the rest of the play is mediocre), 154 (witty twinning for castling, but thin from strategic point of view and with pin-mate only in one solution),
 155 (hackneyed reciprocal white batteries),
 156 (unbalanced white play with tempo only in one solution),
 158 (not particularly interesting),
 208 (a HOTF with dual-avoidance square blocks in the first pair of solutions and critical Grimshaw interferences in the second, but excessive twinning and the move B×c3 is very weak).

The single-double step moves of the same white pawn in 211 working as sacrifices that vacate the mate square are interesting, but the practically inexistent black play leaves no room for a distinction.

Awkward captures of black pieces in 213 without any meaningful strategy except for the mutual vacation of mate squares between the white pieces. The captures of BB in 218 are very unattractive.

Familiar Kniest and Zilahi play in 219 with the WR and WB breaking the wall of the black pawns and the WS carrying out dissimilar manoeuvres. Nice line clearances with white sacrifices in 220, but the repeated moves are not appealing.

2 solutions

1st-2nd Prize 160 Degener & Degenkolbe :

A lovely Minimal with two distinct manoeuvres leading to the same finale ; in one solution the WB has to carry out a critical move to allow the black castling and in the other he should move away from the diagonal (without obstructing the route of BR with the move Be8) to allow the BK reach to the mate square.

1st-2nd Prize 164 Abdurahmanović & ellinghoven :

Again a WB Minimal, this time a superb strategic single-liner showing black and white Indians with lively and very enjoyable play.
