Long fairy helpmates 9

Our 2nd TT is finished, but this doesn't prevent us from looking at some more longer fairy helpmates *smile*.
Klaus Wenda
1st HM Schach-Echo 1974

1.d5 g4 2.d4 g5 3.d3 gxf6(pf7) 4.dxe2 fxe7(Qd8) 5.exd1S(Bf1) exd8S#

100$ theme - excelsior by both sides finished by two knight promotions. As far as I know not realized in orthodox h#5 yet.

h#5 (4+13)

12th Place Norbet Geissler's Special "37" TT 1995

1.RGd1 (1,6)e2 ... 2.-14. ... (1,6)f8 - g2 - a3 - g4 - a5 - g6 - a7 - g8 - f2 - e8 - d2 - c8 - b2 15.RGb1! (1,6)h3 ... 16.-28. ... (1,6)b4 - h5 - b6 - h7 - g1 - f7 - e1 - d7 - c1 - b7 - h6 - b5 - h4 29.RGb1 (1,6)b3 30.RGb4 (1,6)h2 31.NHa6 (1,6)g8 32.-37. ... (1,6)f2 - e8 - d2 - c8 - b2 - h3#

Thematical tourney was dedicated to problems expressing in any way number 37, here you can see doubled theme: helpmate in 37 and active white piece is (1,6)-leaper and its move is long exactly (square root of 37). Of course very long circuit of white hero.

h#37 (1+2)
(1,6)-leaper d8, royal grasshopper a4
nightrider hopper c2

31st Place Norbet Geissler's Special "37" TT 1995

Set: 1...RFg2 2.(1,5)e8 RFh3 3.(1,5)f3 RFg4+ 4.(1,5)a4 FEb2#

Solution: 1.(1,5)c8 FEb3 2.(1,5)h7 FEc4 3.(1,5)c6 FEd5+ 4.(1,5)d1 RFe2#

Echo with white change of function. Theme "37" is hidden in the sum of coordinates of acting pieces: 11+11+15=37. Strange...

h#4(*) (2+1)
fers a2, royal fers f1
royal (1,5)-leaper d3

7 capturing moves out of 8. All black reborn pieces appear immediately on squares they block in mate. Promotions to bishop and rook.

1.Kh2 Gg1 2.Kg3 Gg4 3.Kh4 Gh3 4.Kg3 Gf3 5.Kh2 Ge2 6.Kh1 Gg2#

Classic! I can't imagine how author could find such simple and elegant position...

Hauke Reddmann wrote as an answer to my rhetoric question:

"..here is the utmost trivial answer:
I first intended to show a king crossing the whole board, pulling some grasshoppers in his wake. One cook, two cooks,...Then I built up, in desperate, the position which was the most simple I could think of, just to check how long a mate with this material would take "usually". And searched for the shortest mate.
To my amazement, I came up with the wacky solution. Revved up the computer to check one day long whether it was the only one, lo and behold, it was.
Just dumb luck."


h#6 (4+1)
3+0 grasshopper
