In 24 minutes on a K7/600 (350 MB hash) Chest finds 4 solutions in 7 moves: Nxb5+ Nxb5 Qexb3+ Nxb3 Qcxb3+ Qbxb3 Bxe7+ Qxe7 Qexe7+ Nbd6 Qe7d6+ Nxd6 Rxa4# Qcxb3+ Nxb3 Nxb5+ Nxb5 Qxb3+ Qbxb3 Bxe7+ Qxe7 Qexe7+ Nbd6 Qe7d6+ Nxd6 Rxa4# Qexb3+ Nxb3 Nxb5+ Nxb5 Qcxb3+ Qbxb3 Bxe7+ Qxe7 Qexe7+ Nbd6 Qe7d6+ Nxd6 Rxa4# Bxe7 Qgxe3 Qfxd1 Bg6 Qbxe3 Q5c5 Q2xb2+ Nxb2 Qdxb3+ Nxb3 Q6xb3+ Qxb3 Rxa4# The last one is surprisingly "quiet".
