In a game I recently played, I was playing White and I blundered quite a bit to reach this position.
[FEN "8/R1N4p/2k5/1pn1K3/8/3r4/P4r2/8 w - - 0 1"]
Is it possible for White to win at all? I had four minutes at hand, and I sat down thinking about all the possible moves I could make by giving the Black king constant checks to win. However, I could not think of anything here.
