I have been recently learning how to deliver a checkmate with 1 rook and 1 king. And I came across this situation in which not matter how much I try, I am not able to find out what to do(I want to deliver checkmate). So, could anyone please help me in find a checkmate. The FEN for the situation is: 8/k7/1R6/K7/8/8/8/8 w - - 0 1
Please if anyone knows the solution, do reply to my post with the solution in it.
