White to move and checkmate in 6.
5K1k/3N1R1r/5R2/8/8/8/8/4r3 w – – 0 1
1. Rg6
1.Kxh7+ Kxh7 2.Kf7 Rh1 3.Rg6 Rf1+ 4.Nf6+ Rxf6 5.Rxf6 Kh8 6.Rh6#
It may be too simple. 1. Rxh7+ Kxh7 2. Kf7 and now 2… Re7+ spoils the simplicity.
after 3. Kxe7 Kg7 there seems to be no checkmate in 6; e.g. 4.Ne5 Kg8 etc.
Hence 1. Rg6! seems to be the only solution.
1. Rg6 Rxf7+ 2. Kxf7 Rf1+ 3. Nf6 Rg1 (stalemate trap) 4. Rh6# (why would you fall into it with a mate available?)
1. … Rg7 (another sm trap, 2. Rxg7 Re8+) 2. Rh6+ (same escape) Rh7 3. Rxh7#
2. … Kh7 3. Nf8+ Kh8 4. Rh6#
2 … Rh1 3. Nf6 Rh7+ 4. Nxh7 Kxh7 5. Rf6 Kh8 6. Rh6# seems to be the longest line
