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 very good. All problems were computer tested (C+).

The 1st Prize from S. K. Balasubramanian & S. Manikumar in the preliminary award is anticipated by Abdelaziz Onkoud, 2nd HM 3° FRME C 30.9.2017 – preliminary award 3.10.2017 (See CE1!) – with an interesting discussion in matplus forum: matplus.net/.../

It is obviously not very important to separate the H#2 section from the helpmates whereas the frequency of problems publishing in KoBulchess has slowed down significantly in recent years.

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.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 (825.20 Kobulchess.com 20.04.2017) and comments on:

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.

Compare to CE2!

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.

A well done blend of Goethart & Gamage interference unpins.

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 CE2!

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).

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.
