Hi Leonid,

Pretz finds a mate in 11 reasonably quick, but it takes a long time on different
settings to lower that to a mate in 10 ... will have to conjure up something to
speed that up:

01:01 WM11 12 Nxg3+ Kg1 Ne2+ Qxe2 Qxb1+ Qce1 Qxg2+ Nxg2 Rxh2 Rb8+ cxb8=Q Rxd7+
Qxd7 Bxd5+ Qdxd5 Qexb1 Qcxd4+ Bxd4 Rh1+ Kf2 Qgg3#

09:36 WM10 10 Nxg3+ Kg1 Rxh2 Rb8+ Kxb8 Bxc7+ Qcxc7 Re8+ Qxe8 Qcf3 Bxd4+ Qxd4
Qxd4+ Qe3 Rxg2+ Qxg2 Qxe3+ Qf2 Qbxb1#

Groetjes,
Paul
