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