Subject: One mate to solve

Author: Peter Berger

Date: 11:36:18 09/06/01

Just saw this interesting one posted at the WinBoard forum (
http://f11.parsimony.net/forum16635/) by Volker Pittlik:

[D]5n2/B3K3/2p2Np1/4k3/7P/3bN1P1/2Prn1P1/1q6 w - - 0 1

It is supposed to be a mate in 30 (source unknown to me).

Chessmaster 8000 can't solve this in 15 minutes on an Athlon 1333:

Analysis by The King 3.12d:

1.Seg4+ Kf5 2.Sh6+ Ke5 3.Sf7+ Kf5 4.Sd6+ Ke5 5.Sg4+ Kd5 6.c4+ Lxc4 7.Se3+ Ke5
8.Sdxc4+ Ke4 9.Sxd2+ Kd3 10.Sxb1 Sh7 11.Kf7 Sxg3 12.Kg7 g5 13.Kxh7 gxh4 14.Sa3
Se4 15.Sac4 c5 16.Kg6
  +-  (8.13)   Tiefe: 14   00:13:58  246285kN

Bringer (http://www.reubold.onlinehome.de) announces a mate in 29 after about
one minute :

0:00:33.6  (11/59)   13872159   5.61  e3-g4  e5-f5  g4-h6  f5-e5  h6-f7  e5-f5
f7-d6  f5-e5  f6-g4  e5-d5  c2-c4
0:01:16.8  (12/59)   32704069   Matt in 29  e3-g4   (Mat=-1320,50=1)
0:01:45.0  (12/59)   49458897   Matt in 29  e3-g4  e5-f5   (Mat=-1320,50=2)

What do others think ?

Cheers,
