Originals from Springaren 84

After some time I again had the chance to look at some Springaren originals. But I hadn't enough energy to solve, so I simply chose these that looked promising (after reading the comments of editors or given the name above the diagram) and set them to Popeye. Well, the result seems worth of spent time...

1.e3? th. 2.Rd4#
1...Sd5, Sc6 2.b6#, bxc6#

1.Qb7! th. 2.Qe4#
1...Sd5, Sc6 2.Qxd5#, Qxc6#

9673 shows theme of 4th WCCT - key destructs white battery that acted in try (or in set) and changes mates. Here there is further unfication in solution - both mates capture knights.

1.Kb4? th. 2.Qd3#, Qe2+, 1...Bc5+!

1.Qb7? th. 2.Qxd5#, 1...Rd1!

1.b7! th. 2.Rxe6+ Bxe6 3.Qxe6#
1...Bxg3 2.Kb4! th. 3.Qd3#, Qxe2#, 2...Bxd6+ 3.Sxd6#
1...Bd4 2.Qc6! th. 3.Qxd5#, 2...Be5 3.Sg5#
(1...Bb6 2.Kxb6! th. 3.Qd3#, Qxe2#)

First try and first variation show Roman theme - effective defence 1.Kb4? Bc5+! is after move defending threat of key 1...Bxg3 substitued by weaker defence 2.Kb4! Bxd6+? Other try and variation are more complicated. Main plan ("move wQ to a8-d5 diagonal and threat Qxd5#") is executed by different moves of wQ due to different positions of wp. Refutation of try (1.Qb7? Rd1!) is after bishop defence substituted by another bishop move unpinng pawn. Complex composition!

1.Bf5! th. 2.Qd3+ Rd4 3.e4#, Be4#, 2...Bd4 3.Be4#, Qe4#, 2...Sd4 3.Qe4#, e4#
1...Rd4 2.e4+ Rxe4 3.Qxe4#
1...Rxf4 2.Be4+ Rxe4, Ke5 3.Qxe4#, Sc6#
1...Sxf4 2.Qe4+ Rxe4 3.Rxc5#
(1...Sg5 2.Rd8+ Sd7 3.Rxd7#
1...Rxf5 2.Qxf5+ Be5 3.Qxe5#)

Unusual formal theme: 3 white mates on e4 appear in threat after 3 black defences on d4 - one mate is always avoided by various effects - R keeps guarding e4, B pins pe3 and S unblocks e6. These 3 white moves then appear as 2nd moves in 3 main variations. Unfortunately mate Qxe4 is repeated.

Perfectly constructed (no wp!) selfmate even with promotions! I omitted some variations with shorter mates.

Sharp idea: using battery of 1st rank white forces movement of bB and creating black royal battery that fires in 4th move.

The end justifies the means... Once upon a time we had here at CCM the discussion about helpmates with moving black king as a twinning - part 1, part 2, some people expressed their concerns and the opinions weren't shared largely. 1st TT CCM proved that there is large space for various ideas and the device can be used for achieving interesting results. Cycle of 8 white moves is surely something exceptional despite lack of strategy.

1.Ke3 c6 2.Qxd4 Re7#

1.Kg3 Bb8 2.Qxd6 Rxg8#

Fine analogy - B1 (1st black move) unpins bQ and moves bK to right position for mate, W1 creates future pin line and unguards by closing black line, B2 opens rook line and selfpins bQ.

1.Bf3 hxg3 2.Sfd5 Qg6#

1.Bb7 h3 2.Sed5 Qg4#

A good deal of symmetry is present in this position with lines heading to both kings (a7-f7, b3-f7, f1-f7, e8-g5), black have to work hard to avoid checking wK and to upin wQ. Opening of e6-g6 is unmatched in other phase.

a) 1.Qb3 Rxe6 2.S2a3 Bb6#

b) 1.Qb4 Re4 2.S4a3 Bxb4#

Similar strategy as in previous problem, but here in 1st move bQ have to choose right square from which she won't directly or indirectly guard mating square. Again S4a3 opens e4-b4 - imbalance.

b) 1.Bxd7 Be5 2.Ke6 Sc7#

c) 1.axb5 Bf6 2.Kxd6 Rd2#

B1 captures white unit guarding squre that bK enters in B2. W1 is unified by three moves of Bc3 on long diagonal. Cyclic Zilahi.

1.Rxd2 Bd3 2.Ke3 Be4+ 3.Ke2 Bf3#

1.Bxd2 Rd3 2.Kxc4 Rd4+ 3.Kc3 Rc4#

Echo diagonal-orthogonal, but not entirely in motivation - Kxc4 annihilates wp and thus allows wR to enter c4, while there is nothing similar in Ke3 move.

1.Kxc5 Rc1 2.Bd5 Rc3 3.dxc3 Be3#

1.d2 Bxd2 2.dxc5 Bc3 3.dxc3 Rd1#

Two sacrifices at c3 are followed by the same black capture. Anyway, transformations the harmless cage around bK into mating nets are interesting.

white stalemates: 1.h7 2.h8R 3.Rxh2 4.Rc2=

black stalemates: 1.Ka1<->Kc1 2.h1Q 3.Qxh6 Qd2=

The phases are unified by similar Messigny-typical stalemate - white piece must guard own king as without this black could have escaped stalemate through exchange of kings' places.

"Trivial" rook checkmate after highly non-trivial play - many sacrifices in order to allow movements of both kings and moreover two rook promotions - of course, queen would have another longer moves.

"Pickaninny", with berolina it includes 5 variations instead of well known 4 with usual pawn. But the play is mechanical, it is simple hunt for black berolina, symmetrical.

General stategy is simple at the first sight - black provides hurdle for Gh7 and battery mate follows. But white lacks tempo moves, that's why B1 must provide him one. It is possible to do this everything eight times - providing 8 different squares for wK!

1...RLb7 2.Se7! th. 3.RLh5#
    2...RLb7~, c6 3.Sc6#, Sg6#

Multiple line combinations: threat changes white lines to d5 and e6 and black defends Lewmann-like by anticipatory closing, but with lions anticipatory line deactivating is the same as its activating, white exploits that on e4, f6 respectively in 2nd move, threatening mate RLh5, that's why Black deactivates lines activated in defence - RL~ allows Sc6 by anticipatory activating, while c6 changes activated and deactivated line allowing further change of line activated by white S.

1.Nxg2 Nxf6 2.Nxc4 Gf7#

1.Gxe2 Gf7 2.Gc4 Nxf6#

White needs only 3 "effects" to mate Black: move Gf7, move Nxf6 and remove guard from one of rear pieces of white batteries - Ne2 or Gg2. So Black helps him by capturing other rear piece avoiding battery check that would destroy the plans and as this provides additional guard on other battery line, black piece goes back on the same line interfering with other piece -a kind of G-N Grimshaw. Well done.

Notorious critics can say that Madrasi is simple for achieving AUW effect and I'm known as being not very friendly with promotions in general. But 12 various answers to triple AUW, it is for me considerable achievement. I'm even ready to come across repeated 2.Rxc3 without many words...

Here there are 4 AUWs, followed by 16 various answers by White, considerable too, but more symmetrical and moreover, Circe is rather underused - only in 2 variations.

Well, I set this problem to Popeye, but it refused to solve it, with "too fairy" message... But task nature was so clear - at least the set play - that I managed to solve it from diagram despite Mars Circe uncomfortable complicated visualisation. It was almost clear that 1.Nd1 immobilizes two black grasshoppers and blocks d1. After some minutes I realized that it also allows other promotion mates. Great - Franta Sabol becomes real Mars Circe expert!
