Problem 822: Francesco Simoni - Helpmate
francesco.simoni(17.04.2017) Happy to publish this complex helpmate from the Italian master!  It is another ideal example of the 'Organised disharmony' popularised by Zivko.
 
 
 
 
 
 
 
 
 
 
 
 
822. Francesco Simoni (Italy) 
822
H#2         3 Sol.         (6+14)
 
1.Bxc3 Rxg4 (Sxg4?) 2.Bf6 Re4#
1.Rd6 Sxg4 (Rxg4?) 2.Rf6 Sf2#
1.g5 h5 (Rxg4? Sxg4?) 2.Rf6 Bxg4# 
 

Tries fail for want of tempo W1.

1.Bxc3 ~?  2.Bf6 Bxg4

1.Rd6 ~?  2.Rf6 Bxg4
 
Three solutions with the common strategy of selfblocks in the same square by different pieces. In the solutions 1.Bxc3 and 1.Rd6, if white had a tempo move, it could mate with 2...Bxg4, but white doesn't have such a move, so it forms a battery in W1, with reciprocal dual avoidance for the indirect white pin due to B1. It follows a battery mate with Switchback.
 
In the third solution, instead, the pawn move 1.g5 prevents the previous strategy, but the selfblock in g5 allows 2...h5 to guard g6, so the mate Bxg4 is now possible.  (Author)

Very unusual idea.
Pity that BB cannot be placed on d2 in initial position due to cook...

Problem 822 is not the worst example of Organized Disharmony, but it is artificial: the bRh6 is completely useless, it is here only to add the badly matched solution. In my view it is preferable the 2 solutions form replacing the misused bQ with the indicted bR.

The white mechanism is nice and does not seems anticipated.
If so, Vitaly would have already found the forerunners. :-)
Two illustrative examples of it through direct unpinning.
7B1/4pp1K/3pk2S/5R2/7q/8/2b5/b7 (4+7)
h#2 2 solutions
1.Ba4, Rxf7 2.Bd7, Rf5# 1.Qa4, Sxf7 2.Qd7, Sh6#

r5q1/1r4p1/8/8/2R5/S2k4/Kpppp3/1B1S4 (4+10)
h#2 3 solutions 1.Re8, Sxc2 2.Re3, Sa3#
1.Qe8, Rxc2. 2.Qe3, Rc4# 1.Re7, Kb3 2.Re3, Bxc2#

Searching for not well matched solutions in Helpmate I found the following work:

M. Kovacevic, 11 Place, 8.WCCT
4b2b/1p4s1/5Ksr/p2q4/7p/1B1k4/R2P2p1/8
h#3 b)Pd2-->e3
a)1.Qg8, Rxa5 2.Se6+, Kf5 3.Kd4, Rd5#
b)1.Qh5, Ra3 2.Sf5+, Ke6 3.Ke4, Bd5#

It is remarkable that it fullfills the 8, 9 and 10.WCCT-themes at one time!

The most closer in respect of pattern and content, though partially, is the following:

pdb.dieschwalbe.de/search.jsp?expression=PROBID=%27P1088036%27

On my opinion, these problems cannot be considered as forerunners, since the motivation differs radically.

Not being an apologist of 'Organized Disharmony' concept, I would agree with you but we should respect other views :-)

I suppose, the correct FENs are:
6B1/4pp1K/3pk2N/5R2/7q/8/2b5/b7

r5q1/1r4p1/8/8/2R5/N2k4/Kpbpp3/1B6 (in your version WS doesn't participates in final position ending with Bxc2#)

Thanks Vitaly!
It seems that the already known white mechanism can give rise to many interesting versions (except the Rope theme, I think).

I don't like the helpmates with not well matched solutions especially when there are remarkable flaws regarding economy and when there is too distance between main and side solutions in terms of content (and visual impact),

The FENs are correct.
The jobless wS in third solution is unpleasant.Slightly better are:

8/QP6/8/6P1/5kb1/4R1p1/1r4pB/r4SK1 (4+9)
1.Ra5, Sxg3 2.Rf5, Sf1# 1.Qa5, Rxg3 2.Qf5, Re3#
1.Rb5, Kxg2 2.Kf5, Bxg3#

8/8/1b6/5p2/5kbs/4R1p1/6pB/3q1SK1 (4+8)
1.Qd8, Sxg3 2.Qg5, Sf1# 1.Bd8, Rxg3 2.Bg5, Re3#
1.Sf3+, Kxg2 2.Sg5, Bxg3#

I like a Meredith version, here is the diagram:
Version/reworking? by Rodolfo Riva

1.Qd8 Sxg3 2.Qg5 Sf1#

1.Bd8 Rxg3 2.Bg5 Re3#

1.Sf3+ Kxg2 2.Sg5 Bxg3#

Let me explain my choices. With only two solutions with R and S or two R or two S, the scheme seems rather familiar to me, so I considered the opportunity to insert a third solution, which is logically connected to the first two and so in harmony with them, although the strategic content is not (and cannot be) perfectly homogeneous.
Homogeneity is a cardinal point, but I think it's opportune to search new ways in helpmate in two, to keep alive this charming stipulation.
The diagrammed problem by Mountecidis shows the classical idea of cross-checks with Switchback, which is present in many other helpmates and I also composed some.
The nice and instructive problem #11, doesn't have the dual avoidance.

I realized the problem 822 while I was composing for the 185 TT of SuperProblem, this should explain the choice of the pins in B1. But with only the two thematic solutions I considered it insufficient for that tourney and so I added the third solution.

Rodolfo, I agree that the strategic content of the solution 1.g5 is poor, when compared with the content of the other two solutions, but it is far from artificial, IMHO, because 1. g5 it's not a neutral move, but it prevents 1 ... Rxg4 and 1 ... Sxg4. I'm sorry that the dual avoidance after 1. g5 is not pure, but at least the economy is rough. Be sure this problem is the result of some study, not the first version that came to my mind.

For example, consider the following version

1b6/2p1p2q/4P1n1/5Bp1/3pp3/p1pk2Np/r1b1R2K/2r5

H#2 3.1.1.1 (5+15)

1.Bb3 Sxe4 2.Bc4 Sg3‡
1.c5 Rxe4 2.c4 Re2‡
1.Se5 Bxh7 2.Sc4 Bxe4‡

Tries, failling since no tempo W1
1.Bb3 ~ ? 2.Bc4 Bxe4‡
1.c5 ~ ? 2.c4 Bxe4‡

Dual avoidance for line opening after 1.Se5. I like it, but there are too many similarity to consider it an original for another tourney, I think. I discarted it because the capture 1...Bxh7 is too strong, better to try other ways, in my opinion and the 822 was born.

PANTA REI ? I know the Greek bad words but this is new to me! :-)
I found the version with Rope.theme (it was inspired by the M. Semrinec - P1088036 quoted in #5). There are also interesting tries: 1.Rg5; and 1.Sg3;

8/K2R3r/1Sp1kp3/3pp2s/8/1B6/6r1/6b1 4+9
1.Rf2, Sxd5 2, Rf5+, Sb6# 1.Sg7, Rxd5 2.Sf5+, Rd7#

Of course my preferred version is the 4+7 (#3) where is more emphasis on the black play on same square.

I like the Gruber helpmate, with interferences, because it offers a good interplay.

I agree.
By the way, there is W-B form of Klasinc theme (in Gruber's work) which is a part of recently announced Belgrade Internet Tourneys 2017 theme in Group B (h#2)
