Subject: A very difficult forced mate - can anybody find it?

Very recently, Christian Bartsch showed a very interesting position in the FCP
forum:

[D] 6k1/ppb2p2/2p1rR1K/3p3p/6bP/N1PB2Pq/P4Q2/8 w - -

It is from Jean Dufresne - Adolf Anderssen Berlin 1851. The only move to save
the game is Bg6. But this moves even wins. After: 1. Bg6 Qxg3 2. Bxf7+ Kh8 3.
Bxe6 Qxf2 4. Rxf2 Bxe6 Can any engine/mate solver see a forced mate after those
moves?

[D] 7k/ppb5/2p1b2K/3p3p/7P/N1P5/P4R2/8 w - - 0 5

My engine cannot see it in reasonable time. When I analyze some variations from
back to front, I see, that Rf8+ can announce mate in 15 (or even shorter?)

Regards,
Dieter
