With my favorite "Leonid parameters" in Yace, AMD K6-2 475, 20M hash, running in
the background:
nodes time score depth
122249 2.535 9.91 1. 1.N8xb6+ Nxb6+ 2.Nxb6+ Qfxb6 3.Qxf8 {1011}

After this was rather fast, I also tried my current default parameters. Yace
found a different mating line:
2396222 44.092 0.95 3. 1.Qgxd4+ Qxd4 2.N8xb6+ Nxb6+ 3.Nxb6+ Qfxb6
4.Rxd4+ Nbxd4 5.Qxf8 Rxc7+ 6.Bxc7 {360}
2406208 44.282 1.35 4++ 1.Qgxd4+ Qxd4 2.N8xb6+ Nxb6+ 3.Nxb6+ Qbxb6
4.Rxd4+ Nbxd4 5.N4xf6+ Qfxf6 6.Nxf6+ Qxf6 {1182}
3992856 1:10.7 Mat08 4t 1.Qgxd4+ Qxd4 2.N8xb6+ Nxb6+ 3.Nxb6+ Qfxb6
4.Qxd4+ Nbxd4 5.Qcxc5+ Qxc5H 6.Qxc5+H Qxc5H
