Hello Richard and all,
You meant to write "Rdxd7" instead.
I forgot to state that Rc1 is not possible. This could only occur if the
two
pawns at Pc3 and Pc6 were removed.
After black moves the rook to f8, black can create some counter play by
attacking. Black can take the white rook at d7 slowing white's attack.
Then,
the white rook at e7 takes the black rook at d7. White can then bring the
knight into play.

Hello Edward,
I think your first two moves are correct:
1. Qxd7 Qxd7
2. Rcxd7, this looks correct so far. White has won a bishop and the four
rooks have somewhat of a standoff. This may well be the whole point of the
problem.
Now you say:
2. ... Rc1, threatening Rc#1, but I don't understand the threat as there
are two pawns and a bishop to go through first and the knight at f3 can
block.
Meanwhile the two rooks on the seventh rank can go after the pawns.
Richard

Hello all,
Doctor Z has his scalpel ready. My solution:
1. Qxd7 (Queen takes bishop.) Rxd7 (Rook takes queen.)
2. Rxe8++ (Rook takes rook for checkmate.)
1. -Qxd7 (Queen takes queen.)
2. Rdxd7 (Rook at d1 takes queen.)
If black takes a white rook, white takes the other black rook for
checkmate.
2. -Rc8 (threatening Rc1++)
3. Nf1 (blocks potential checkmate) This move would allow black's rook to
pin
the knight to the king. If black makes Rc1 now, white wins with Rxe8++.
3. H3 (creating an escape square) Rc1+
4. Kh2 (White knight can join the attack now.) Rc8 (protecting rook at e8)
Otherwise, white wins with Rxe8++.
2. -Rf8 (protecting f7 pawn)
3. Bb3 (Bishop targets f7 pawn.)
The bishop pins the pawn to the king. Two rooks and bishop attack the f7
pawn
for white. Black has a rook and king defending the f7 pawn. Since white
has
three pieces attacking f7 and black has two pieces defending, white will
capture the f7 pawn.
