Good old times 8

Let's move further. Having covered feenschach issue 87 extensively, here you can find six problems I have liked in the issue 91, dated May-August 1989.

Besides, the issue contained also an excellent h#6 by Tichomir Hernadi, showing 2+2 queen promotion that I have presented as an example for the 11th TT CCM C 28.2.2003.

a) 1...c8PR 2.Kxe8 PRd6#

b) 1...c8PA 2.Kxe8 PAc7#

Not exactly an example for the currently running 24th TT CCM C 10.10.2008 as there are only 2 positions here. But there can be a possibility of multiplying the content by introducing some other fairy piece.

h#1,5 (4+2)
a) princess e8
b) pao e8

Andernach tourney in 1989 was dedicated to stalemate problems with normal orthodox kings in which all 8 squares next to the stalemated king are empty during the whole solution. Mutual paralysis in Madrasi allows guarding such squares. If nightriders are used, one pair can take care of two squares, therefore four pairs of mutually paralyzed nightriders are needed. To reach this aim, 5 nightrider promotions are needed.

h=6 (7+12)
1+4 nightrider

1st Prize Andernach 1989

If the previous problem have won only the third prize, what could have won the tourney? Somethig like this:

1.Ke6 2.c1Q 3.Qxc6 4.Qh1 5.c5 ... 9.c1R 10.Rc5 11.Rg5 12.Rg1 13.g5 ... 16.g2 Qxd4=

In the initial position bK is surrounded by 8 empty squares and it moves to another square with 8 empty squares around.

ser-h=16 (6+10)

Any single phase is nothing special, but together they form great whole.

Two of three black pawns on the second rank are blocked by reborn white pieces, captured in cycle BQ-BS-SQ, the third black pawn promotes to the capturing piece and finally is captured on its own Circe square.

Interesting geometry. Actually all bishop moves are tempo moves - and they are precisely determined by collisions with important Black unit - future blocker of c1.

Typical for Duel chess. White needs to promote pf2, but this is initially prevented by two pieces on f-file. To ensure bK does not escape, check by bishop must take place first, the bishop is then sacrificed. The other bishop eats pf3 and is sacrificed too. Rook promotion instead of queen is nice Duel extra.
