Final AWARD in informal tourney «Problemist of Ukraine - 2010». HelpmatesI thank the editorial staff of the magazine for honour to evaluate the chess works in the rather numerous international tourney. 84 originals (44 h#2, 25 h#3, 15 h#N) from 48 authors from Argentina, Azerbaijan, Belarus, Brazil, Bulgaria, Czech Republic, England, Lithuania, Macedonia, Moldova, Poland, Romania, Russia, Slovakia and Ukraine were published in the magazine during 2010 year. The general level of chess works is not high. H#N section has turned out to be the most weak. Problems with uninteresting play and obvious defects (such as unmatched play of both sides in phases, unnecessary repetition of moves, idle white officers in mate positions, unsatisfactory construction or twinning form, evident symmetry in play) were excluded from awarding. The report contents direct links to the chess problem database server http://www.softdecc.com/pdb/index.jsp. Í7 – not a quite matched play of the Black; in addition partially anticipated: P0525341 [rn2k2r/p4b2/4B3/8/8/8/K7/1R2R1q1 h#2 2.1..], P0525358 [r2bk2r/3p1p2/8/8/8/8/4K3/5RR1 h#2 2.1..]. H8 – in diagram position there is a B-B Umnov effect instead of Bristol theme; in three phases the idea has been already realized with more interesting white play: P0535028 [b1n4n/1P6/8/1B1p1p1K/8/8/rb3kp1/qr6 h#2 b),c)Kf2->b6,f7]. H9 - a similar idea has been already shown with more matched black play: P0578160 [2R3B1/1pn5/5P2/1NnP4/1qk1PR2/2N2P2/K4brr/8 h#2 b)Kc3->c1]. H16 - see the similar problem with more harmonious play: P0573977 [b5K1/8/2p1R3/pnpp4/Bpk5/2rp4/2r5/2n5 h#3 2.1..]. H18 - a crude play in 2nd solution. H19 - the idea is rather interesting but the construction is not optimal: Qc7 can be replaced by BP and one can place two black knights instead of BRb7 & BBa8. WS can be moved to e5 square in initial position for greater paradoxicality of the twin (C+). H30 - anticipated: P1070907 [q1R3BK/2b1p3/4p3/pn6/ppkn4/3pp3/b3r3/2r5 h#3 2.1..]. See also P1098928. H32 - anticipated: P1185731 [8/8/qB2k3/3r4/4K3/8/6N1/8 h#3 2.1..]. H36 - a great number of similar problems with more harmonious play of both sides, e.g. P1078666 [8/6B1/3kn3/8/2R1q1P1/6P1/6p1/5bK1 h#3 b)-Se6]. See also P1005203, P1085194, P1072748. H35 - a solution that ends with Be3# move differs strongly (in terms of content) from the other two ones. In my opinion, it is better to leave two phases in a light construction: 8/6B1/3K4/4P3/2rk4/1pRn1n2/3b4/8 h#3 2.1.. (C+) H38 and H40 have the same defects: radical twinning form and symmetry in the play of both sides. H41 - heterogeneous play in phases and the repeated moves of BK. H46 - multiple predecessors, for instance:P0547553 [2k5/8/8/5R2/1K2p3/2Bp3B/8/2Rq4 h#2 2.1..]. H47 - a phase beginning with 1.Sg6 differs strongly from the rest content of the problem and contains repetitions of moves in the play of WSs. H48 - in a mate position of two solutions WBh7 is idle plus repetition of 2.Sfd4. The following version could deserve a distinction: 4n3/4P3/8/4k1P1/5n1R/1N6/7B/K4R2 h#2 3.1.. (C+). H53 - a combination of Grimshaw with Pickabish interferences has been already shown in more ambitious work: P0565535 [3K2B1/1br1ppb1/3R1R2/2p5/8/B4p2/2k5/1r6 h#2 2.1..]. H54 - in my view, an unsuccessful attempt of improvement of author's older work P1094761 (52 Chess Leopolis, 2009, No 3621): solution beginning with 1.g4-g3 does not match to the general concept of the play and contains a repetition of mating move (Sf4#). H55 - taking into account the task idea, a radical twinning form could have been forgiven but the idle white officers in mate positions of 'c' and 'd' twins - no way. H56 - repetition of B2 and unjustified heavy construction. H59 - anticipated: P0524502 [N7/8/3r3q/5K2/2k5/3rp3/6B1/N7 h#3 b) Bg2->g7]. H63 and H84 demonstrate a combination of slow Excelsior with Phoenix theme that has been shown many times. See e.g. P0559635 [8/8/8/1K6/4p3/k7/1p2Pp2/8 h#7], P0533815 [4k2r/8/8/7p/8/4p3/4P3/5K2 h#7]. H64 - anticipated: P0557829 [8/8/8/8/5p2/N1N1pk2/5p1K/8 h#2 b)Kh2->h4]. H65 - unmatched play of both sides in phases plus repetition of the move Rf4. H66 - anticipated: P1106433 [K7/8/1N6/1bpR4/Bn6/2k5/rb4q1/8 h#2 b)Ka8<->Qg2], P0541617 [8/rR1K4/3N4/5B2/6b1/2k5/3p4/8 h#2 b)Pd2->d4]. H67 - there is a superfluous WB in solution beginning with move Sb4. H69 - repetition of B2 in pairs of solutions plus superfluous WB in solution finishing with Qe4#. These defects can be eliminated: KQ4r1/Pp3pp1/bP3p2/3r4/PBk1p3/1pbR1n1q/8/1n6 h#2 4.1..(C+). Í70 - anticipated: P1213852 [3K1n2/3b2BQ/6q1/8/2n1k1rR/3rp3/8/8 h#2 2.1..]. H72 - a play in the phase that begins with Qe6 does not correspond to the play in the other two phases. Furthermore the idea of a cyclic pin of two black pieces is known: P0504406, P1106182. H80 - a syntheses of Indian theme with Maslar theme has been realized in Neiman form more than once: P1087780 [5K1n/p1n2p1b/5bp1/3krBpp/P4R2/2ppr3/8/7q h#3 4.1..]. See also: P1073779. All the competing helpmates were divided into three usual sections. I have been using the following abbreviations in my comments: B1 (2,3 etc.) the first (second, third, etc.) move of the Black; W1 (2,3 etc.) - the first (second, third, etc.) move of the White. I propose the following award. Helpmates in 2 moves
Helpmates in 3 moves
Helpmates in more than 3 moves
