Problem 824: Preet Vardhan - Helpmate
preet.vardhan(18.04.2017) Welcome to Preet Vardhan. He started composing recently and his first composed problem shows the nice theme of  'twoway interference' with excellent dual avoidance.  Hope he comes up with more of the same quality!
 
He is from a group of four promising newcomers from India who are the product of the efforts of the seniors through a Whatsapp group. The group includes N.Velmurugan (See 800) and Dr. S.Manikumar who have already shown their mettle in  the recent Quick composing tourneys of the Superproblems.  I will soon publish a few originals of the fourth member of the group Dr.Phani Bhushan.

Nice one Vitaly. But Preet's has dual avoidance & selfblocks on the same square !

It might be worth the extra men.

Interaction between BQ and BR in each solution (a mechanism) is better than that dual avoidance, on my glance.
A clear mechanism which unifies all phases of chess problem is the main goal in composing of strategical helpmates, I belief.

@ Vitaly sir, The main theme involved here is change in direction of interference - something like to and fro blocks. This is lost in your version sir.

Manikumar, my example is not a version, it just an illustration how to enrich unity of Black's play. I think a unified mechanism is better than a trivial dual avoidance with alternate self-blocks.
It is very important to give the right direction in composing from the very beginning.
I wish goog luck to the new author!

Vitaly,
the Qg2 is horrible!

1K6/8/2pS4/3k4/2r2PS1/8/7R/6b1 looks better.

I prefer the original with interference in both directions.

Rodolfo, I suppose this is an emotional evaluation. :-)

Yes, BB instead of BQ looks better but economy wasn't my point. My point was interaction between two black pieces in each solution. I have intentionaly ignored the difference between arrival effects on B1 in solutions.

In the following position, is Rc6 repeated in both the solutions a drawback?

7K/2pN4/r2k4/2N2P2/8/8/6q1/6R1

1.Qb7 f6 2.Rc6 Rd1#
1.Qd5 Rg7 2.Rc6 Sb7#

The interaction between BR and BQ though is less beautiful than Vitaly's illustration.

Repeated move Ra6-c6 is a drawback, definitely

There is no interaction between the black pieces in the scheme at #7?
Departure and arrival effects are the central point in both versions and it is impossible to ignore the difference between the arrival effects on B1.

Probably, there is misunderstanding. My English is not perfect, sorry.
Quote:

Of course, there is! Your version suggested in comment #7 is better than mine. I meant I wasn't paying attention to economy while composing my illustration.
Quote:

Yes, I agree with this. I have ignored the difference intentionaly since the central point of my illustration was intersction between two black units.

Обе версии, и #2 Vitaly Medintsev, и #7 Rodolfo Riva по содержанию и показателям, которые заложены в Анализатор от Viktoras Paliulionis абсолютно равнозначны. Чёрный ферзь не такой и ужасный, если учесть, что для него гораздо сложнее организовать Hideaway.

Сравнивая версии, представленные в комментариях #2 и #7, версию Rodolfo следует признать лучшей - в соответствии с принципом экономии силы (economy of force)

About #4, I agree that unity is the main goal in composing, but I think the first point is too general and possibly even subjective to be approved. I appreciate the istructional example of Vitaly and versions, emphasizing the importance of interaction play between pieces and I like the nice problem by V. Preet Vardhan, where moves in the same direction are followed by interferences in opposite direction, that is fine and paradoxical, in my opinion. If we want, we can note an unbalance in problem 824: the move 1.Bc7 is a pure critical move, while 1.Be5 is merely a selfblock. Also, the interferences in B2 are not pure, which of course makes easier the goal. These, I think, are possible points the author may consider to realize other compositions on the idea.

Thank you Vitaly, Rodolfo Riva, Yuri Bilokin and Francesco Simoni. The wealth of the varying views and the instructive examples are very very useful for a newcomer like Mr.Preet and even for more experienced composers.

I agree with Francesco that despite the minus points he mentioned, Preet's paradoxical idea of interferences on both directions is as important as better coordination between black pieces. Mr.Preet is very happy that his problem received so much attention.

Yes, this feature (that was noticed by Rodolfo in comment #2) is very clever and probably original. I have missed it.
So my illustration is not quite appropriate :-)

This idea can be expressed as follows.
The content is much richer than the source.
Preliminary coating of black figures, selfblock, model mates, change of function of white figures
