Problem 272: Balasubramanian & Vlaicu Crisan - Fairy (Circe, Take & Make, KoBul Kings)

balasubramaniancrisan(06.11.2013) Wonderful fairy original with rich thematic content by the tandem S.K.Balasubramanian and Vlaicu Crisan!


 


272

1.Bxf4-e5(+bBf8)(bK=rB) Se3 2.Rxh5-h1(+bRa8)(bK=rR)+ d6xe5-h2(+wBc1)(wK=rB)#

1.Rxh5-b5(+bRa8)(bK=rR) Sh2 2.Bxf4-c1(+bBf8)(bK=rB)+ a6xb5-g5(+wRh1)(wK=rR)#

 

Exchange of roles between 2 pairs of pieces: Between wR and wB and between bR and bB.

Black battery formation with the front line pieces being bPs and the rear pieces appearing due to rebirth.

Anticipatory line closings by bS on the squares vacated by wB/wR to avoid self-checks. ODT.

(Authors)

Circe: the captured pieces reappear on their game-array squares.

Take & Make: Every capture ("take") must be complemented by a further step ("make": not a capture) by the capturing piece, using the movement of the captured unit, otherwise the capture is illegal. Pawns may not end up on their own first rank.

KoBul Kings - When a piece (not a pawn) of his own side is captured, a King transforms into a Royal piece of the same type as the captured one. When the King is in the form of any Royal piece and there is a capture of one of the pawns of his own side, he becomes a normal King again.

This is one of the best problems published here this year in my opinion and actually I don't understand how it do not obtain any reactions... Very dynamical play (1...Se3/Sh2 are really beautiful and surprizing). Full harmony between both solutions!

This is indeed an idea with beautiful logic chain, suprisingly rich for hs#2.

But the pieces are not perfectly used. The rebirth of wB/wR looks thematic and potentially could be a reason for B2, the rebirth of bR/bB in W2 is superfluous. Actually it spoils the effect of selfdefending bBf8 in 1st solution.

A rough example illustrates some of the points.
W: Pf6,Pg6,Ka3,Bh2,Rg1;
B: Pa6,Pd6,Kh6,Pc4,Bf4,Pc3,Sf3,Pc2,Rb1

Hm, Nikola, are you sure that the position in your comment is correct? I can not find the solutions...

It's the same problem with added flightblocking functions of wB/bB and pure arrival purpose of 2.bSe3. Of, course the conditions should be added :):
Take&Make Circe Kobul, hs#2
1.Bxf4-e5[rBh6][+bBf8 Sd2 2.Rxb1-h1[rRh6][+bRa8]+ dxe5-h2[rBa3][+wBc1]#
1.Rxb1-b5[rRh6][+bRa8] Sh4 2.Bxf4-c1[rBh6][+bBf8]+ axb5-g5[rRa3][+wRh1]#

Now I realize that WinChloe can not find solutions not only of your version, but also of the original... Strange why...

About your version - you know my opinion that if some thematic effect is realized only in one of both solutions this is more like weakness because decrease the harmony impression. In this version only first solution is with self-blocks by Bs, so I prefere the decision of the authors to avoid it and to make full analogy between solutions. Also there the bS play on squares just vacated by wB/R which is nice.

But basically you are right that if these rebirth are used the problem will be even better. Unfortunately this looks impossible.

My example, NOT A VERSION, only illustrates what would be better for Bishops, wB selfblocks in 1st and checks forcing selfmate in 2nd solution, while bB selfblocks in 2nd and mates in 1st solution.
For the Rooks it looks impossible in hs#2 but it would be worth to try it in longer play.
In the original, wB can be on c1,d2,e3 and wR on h1,h2,h3,h4. I simply can't see any significance in completely accidental Umnov effect. To me it is more like a boring and annoying hollow fashion than a nice effect.
But the most interesting and as you say surprising PURE ARRIVAL effect 1...Sh2 is missing in the first solution: bS DEPARTS from g4 away from h-file and ARRIVES to e3, the only square suitable for the DEPARTURE purpose. In the example, bSf3 could arrive to d4 serving to DEPARTURE purpose, so 1...Sd2 has a PURE ARRIVAL purpose. That's where the thematic analogy comes prior to all accidental effects.

Diyan wrotes: Now I realize that WinChloe can not find solutions not only of your version, but also of the original... Strange why...

Those solutions (original) can be found with Popeye, but if you look positions after W2, in first solution WR is checking rBR and in second WB is checking rBB. Now here black needs to mate which he doesn't want to do. The Royal piece can in both solutions capture the checking piece and there is no mate. One has to ask in this case which fairy condition is used first: Take&Make or KobulKings?

Nikola, thank you for sharing you opinion and full explanations!

Kenneth, in both solutions black Royal piece can not capture the checking white pieces, because after Take&Make move by the black Royal piece they will re-appear again (because of Circe) and this is selfcheck. Thats why the only defence on B2 is the closing line by bPs as in the solution.

Yes, you are right, but still I'm wondering are WinChloe and Popeye taking these fairy condition in some order or all at the same time?

This idea is so rich that it is hard to give a full explanation of the content.
Black will mate playing 2...a6xb5#. This requires wR on b5 and self-guarding bR on a8 (because wK must be in the phase of Royal Rook). Black must be forced to play axb5, so this move should parry the check by wB (axb5-g5). This must be the only legal black move so bK must be in the phase of Royal Bishop and therefore wB must be self-guarded on c1. Also, bS must not be able to parry that check so it must depart from g4, possibly to e5,f2,f6 or h2. axb5 brings wR to h1 and this could be legal only if bS has arrived to h2, otherwise 2.Bxf4-c1 would be mate to bK. A fantastic chain of motivations for only 2 white and 1 black moves. These motivations both force and legalize the last black mating move.
To match this fully in the other solution (with pure arrival purpose), bS should be on g2 (with wRh4 for the "nice effect").

Kenneth, I think that there can't be a different order of conditions because Take&Make is condition as a whole. We can't divide and separate the parts of it. Circe can't be applied before the capture and also can't be inserted between Take part and Make part.

A new condition Take&Circe&Make might be defined, but would it bring some interesting possibilities.

I fully agree with Diyan's opinion: this is one of the best problems published here this year. All three conditions are justified.
