Good Morning Puzzlers,
The best move is: 1. Rb7
Principle:
The white Rook threatens mate by moving to the eighth rank
black can block mate with 1... Rg8
The white king attacks the black rook.
So white attacks the a-pawn 1. Rb7
Now we have a double attack.
if black moves the a-pawn, white takes the rook!
if black moves the rook, he loses it at g6 or 7 and is mated at g8.
if black moves the rook to a new file,
white moves Rb8+ and black loses the rook after blocking the check.
Rod tells us:
Regarding problem #6, Mr. Fritz says that 1. Rb7 leads to a forced mate in
15 moves. The first few moves of the mating line are:
1. Rb7 Rb5
2. Rxb5 Kg8
3. Rg5+ Kf8
4. Rxg4
Any other first move by white is, at best, a draw.
Richard
