Black has a whole range of powerful threats, including 1...Nxd3 and 1...Bxb7, so White's first move has to be fairly blunt. A sacrifice may be necessary.}]

Since Black threatens to play 1...Nxd3 or 1...Bxb7, White's first move must carry a strong threat. Bearing in mind that sacrifices are appealing to both composer and solver alike, one might be led to try 1  Be4! This multiple bishop sacrifice is the spectacular solution. The powerful threat is 2 Qxe7 mate. If Black plays 1...Kxe4, then 2 Re3 is mate; 1...Rxe4 allows either 2 Rd5 or 2 Qd5 mate, while if Black plays 1...Nxe4 or 1...Bxe4 then the square e4 is blocked and White can mate by 2 Bf4. Thus the sacrifice can't be accepted, but other moves are no help, for example 1...Bd6/Rd6/Rd7 2 Qf5 mate, or 1...e6 2 Qf4 mate.]
