"The most difficult subjects can be explained to the most slow-witted man if he has not formed any idea of them already; but the simplest thing cannot be made clear to the most intelligent man if he is firmly persuaded that he knows already, without a shadow of doubt, what is laid before him." Leo Tolstoy (1828-1910) "The Kingdom of God is Within You" (1894).

1st HM. Something on Rxf3 opening the K-flight to e4 has to be prepared. Thus the key is 1. Qxb5 (2. Bc7+ Kd4 3. Qc4#) creating a QN-battery with many variations: 1.. Rxf3 2. Nf6+ Kd6, Kxf6 (Kf4), Kd4 3. e5#, Qg5#, Bb6# (Nxf3# minor dual); 1.. Nf7 2. Nxe7+ and mates by the Siers-Rössel after the star-flight of the bK 2.. Kd6, Kf6, Kf4, Kd4 3. Nc6#, Ng8#, Ng6#, Nc6#; 1.. Qa1 pinning the wB but unguarding c2 so that so that the Siers-battery strikes again 2. Nxe3+ on the star-flight 2.. Kd4, Kf4, Kf6, Kd6 3. Nc2#, Ng2#, Ng4#, Nc4# Side variations are 1.. exd5, Kd4 2. Qxd5+ Qc4+ Kf4 (Kf6), Ke5 3. Qxf5#, Bc7# A very good problem, rich content and challenging to solve!
