KoBulChess Helpmates in 2 moves 2017 AWARD
logo(29.04.2018) Here is the Award of KoBulChess H#2 2017. Many thanks to Karol Mlynka for his quick and excellent job! The award is open for claims for 1 month period.
In the section helpmates twomovers of KoBulChess Informal Tourney for 2017 on the website http://kobulchess.com/ participated 18 entries (plus several versions also from other authors in comments): 810, 821, 822, 823, 824, 825, 831, 833, 834, 835, 839, 840, 841, 859, 860, 864, 866, 870(22 composers from 12 countries). The general level of the competition was high, above all, the top compositions honored in the tournament. All problems were computer tested (C+).
I would like to express my thanks to the website’s editor Seetharaman Kalyan for inviting me to judge this helpmate tourney, which was a pleasant job to do.
1.Qb7 Sxe6 2.Rd4 Sef4#
1.Rh4 Sxf6 2.Qe4 Sfd5#
1.Rxf4 Rd7 2.Re4 Bxf6#
1.Qxd5 Bh6 2.Qd4 Rxe6#
TF-helpmate in 2+2 phases. In the first pair: unguards of the mating squares (B1), white line-openings for black self-block (Klasinc theme) with capture of black pinned unit by a battery creation and pinmates with shut-off switchback. In the second pair: Zilahi on the mating squares from W2and self-blocks on the exchanged squares and capture of unpinned black unit in mate on the same squares as in the other pair on W1 – that all after homogeneous keys by a good construction. (This beautiful HOTF-composition exists not only because of experts' criticism by 859.)
Compare to 859 and CE1!
1.Bxc7+ Kxc7(Kc5?) 2.Bb5 Rd2#
1.Bxd7 Kxd7(Kd5?) 2.Ba5 Qh2#
An excellent sacrifice Zilahi with gate-opening and a choice of white king?s moves by line-opening. Reciprocal functions of the black half-battery front pieces: each bishop either captures the white unit or plays a hideaway move.
  • Thanks to Internet communication, it was possible to achieve a significantly improved (more economical) joint version of the original composition within a reasonable time horizon.
  • See versions and commentson:
1.Re7 d4 B 2.Re4 Sc7# C (Be8 = A)
1.Re6 Bb5 B 2.Be4 dxc4# C (Sa6 = A)
1.Rc6 Sb8 B 2.Rc5 Bxf7# C (Pd3 = A)
Cyclic changed functions of white pieces Be8, Pd3 and Sa6:
A = passive flight control,
B = active flight control,
C = mating unit.
In this way, the composer has reached a closed3-point 3-part cycle (ABC-CAB-BCA).
All phases with self-blocks in the new Meredith version. A totally unconventional modus operandi for author's creation in this genre.
See the initial position: +bBh8, wPe3?c3 (Devil?s Meredith)
Compare to CE3!
1.Sa8 Rc3+ 2.Kd4 Rd7#
1.Se7 Bc3 2.Kc4 Qa6#
Creation of a white battery on the same square (white Grimshaw) with self-pin by black knights hideaways and pin-mates after anti-cipatory opening of two masked lines. Diagonal/orthogonal cor-respondence.
18 responses on:


1.d3 Sf6+ 2.Be4 Qc1#
1.Qd7 Sb5 2.Sf5 Sed6#
A well done blend of Goethart & Gamage interference unpins.
9 comments: (WRh6 as a weakness point?)
“Technically superfluous units can be vital if looked at from the thematic point of view...“ (after Uri Avner in comment #2)
Transfer of a theme to another genre requires comprehending the essence of both the theme and the genre.“ (comment #3 by N. Predrag) 
1-2.Qxe4 a Sge6+? A 3.Qxe6,
1-2.Qe5 b Bxc5+? B 3.Qxc5,
1-2.Qc3 c dxe3+? C 3.Qxe3;
1.Qe8 Sf7! (controlling e5) 2.Qxe4 a Bxc5# B
1.cxb4 Bxb4! (controlling c3) 2.Qe5 b dxe3# C
1.Qxb4 d3! (controlling e4) 2.Qc3 c Sge6# A
Cyclic flight control and self-block by cyclic dual avoidance. All 8 white pawns can be seen in a helpmate only rarely. It should be emphasized that the author is a successful originator.
Compare to CE3! 
a) 1.Bd4 e5 2.Bc6 Bd6#
b) 1.Rd4 Bd3 2.Rc6 Rb5#
An ingeniously constructed Meredith with double black Grimshaw by self-blocks and critical B1 moves. However, their basic motivation has a different content in the same form: 1.Rd4 shows a help effect of anticipatory interference unpin of white unit (without unguard) while 1.Bd4 only interfered for the unguard of the mating square (without unpin).
(Note: There were no forerunners reported in the comments and the judge also found no anticipated problems.)


1.c1=S Qxa4 2.Sa2 Qd7#
1.c1=R Qxb4 2.Rc3 Qe7#
1.c1=B Qxd5 2.Bg5 Qd7#
Very harmonious processing of unified strategic content. Complex blend of 3-fold change of black underpromotions (B1), direct self-pins (W1)and interference unpins by a promoted unit (B2) –  but in rather heavy position and unfortunately with one repeated mate. The aesthetic and economic criteria had to retreat from the main idea of the composition.  
The award remains open for 1 month period: please address any claims to the editor.
Bratislava, February 2018       Karol Mlynka, International Judge of the FIDE

I think my contribution is not so significant that I would be included as a co-author of Vitaly Medintsev‘s problem.
+2 #6 Vitaly Medintsev 2018-05-06 07:51
I don't mind if it would be a joint problem :-)
