    Recently, I played out a hypothetical game in which one side had a king and rook while the other side had a king and knight. Ultimately, I could not force the weaker side to the edge of the board, and thus, I found no way for checkmate. If anyone has any thoughts or comments (or suggestions for K+N vs. K+R endgames), please post below.

    That's a very difficult endgame, but with best play the game could be a draw. I remember a few months back in a game between two grandmasters, both players made a few mistakes, and the side with K+R ended up forcing checkmate.

    Yeah, this one is much tougher for the defender than bishop vs rook (at least, it is for me!). The stronger side has a lot more winning chances, and there are a lot more positions that are theoretically won (usually when the king and knight are far apart to start with, I think).

    Does anyone else have suggestions about K+R vs. K+N endgames? How does the K+R go about winning?

    I tried to search Chessbase for the game. You can try....there's a game between GMs that's commentated a little bit and there's a K+R K+N ending. I think the game was sometime around May or June.

    EDIT: Found it. I've included the analysis from the chessbase report.
