A very pretty puzzle. The first move was pretty obvious as a way to constrain black’s alternatives, but it is the second move that is much more difficult to find:
1. Rg1
Pins the bishop, keeps the black king in his hole. Forces black to play pawn pushes:
1. …..a4
2. Rc2!
The keystone move in my opinion. I tried out several alternatives, but once I put the rook on c2, the final position immediately popped into my head:
2. …..a3
3. Ke2! a2
4. Kd1
Relieves the pin on the bishop so that black can and is forced to make the move…
4. …..Bc2
5. Kc2#
Dear Yancey,
A beautiful problem.after seeing your solution I shorten the problem to White to move and checkmate in 4.
8/8/8/8/p7/8/3RKR2/kb6 w – – 0 1
without spoiling the beauty of the problem.I dare to go one step further without letting cat out of bag.
Sorry.I meant I dare not go one step further as it would ruin the beauty of the problem.
