Checkmating question

Is it possible to win in a K,R,NvsR,K endgame?

If you have a Knight, then there's always a forking oppurtunity. Granted I don't like the odds but it is possible.

yes, but I think your question is it possible to force checkmate. I don't know the answer to that question.

Although I'm not positive, I can say im 99.98% sure it cannot be forced.

I'm fairly sure it could, but it may take too many moves and the opponent could most likely claim a draw before it happened.

If there is no immediate way to win material, it is a draw with best play from both sides.

From Wikipedia : -
"Rook and a knight versus a rook: this is a theoretical draw, but Judit Polgar lost a famous game to Garry Kasparov when she blundered in a quickplay finish (a sudden death time control) (Nunn 2007:159–61,165). There are five cases that are wins when the defending king is restricted to the edge of the board (Grivas 2008:257)."
Game was in 1996.

According. to the book Fundamental Chess Endings by Muller and Lamprecht, it is a draw. However their opinion is that it is worth playing on if the defending king is confined near the edge of the board. If it is in the corner, the chances of winning are good. The game J. Polgar-Kasparov mentioned in an earlier post was referred to.

For fun, the game in question:
