Here is the famous win of Kasparov against Polgar. I guess that this is of little interest for many players here: if you are a beginner then this ending is always a draw, while if you are a strong player, you use of course tablebases :)
Question...Is Rook and Knight vs Rook a draw?

Kasparov owns.
A passed pawn will make a lot of difference.

cobblepot...wonderful article! Saved it to my toolbar.
costelus...ty for sharing. So the article suggests K would have to be cornered.

yeah, that goes without saying...but there are no pawns on this board. It's just the five of them.
I checked about 25 or so semi-random positions on Shredder's endgame database. Unless there was some lucky tactic available (forced mate, fork, skewer, etc), they were all drawn with best play.

Funny, I was under the impression that Anatasia's mate was another pattern...
As for R+N vs R, I'm pretty sure it's usually a draw, but there's always exceptions.
You're right. I believe this is Anatasia's mate:
I believe the R+N mate is called the Arabian Mate.

I didn't have the nerve to make the draw offer, but the game has been drawn. :)

I think I mentioned somewhere that I suck at naming openings. I guess I can add names of mates to the list as well
See "Secrets of Pawnless Endings" - Nunn, John (Gambit Publications 2002)
Chapter 6 Rook and Knight v Rook - pages 155 to 172
How you can obtain this books in:
You research in Books with the words: "Chess" for books in English; has many books in pdf to free dowload in this page. For example: Secrets of Pawnless Endings
You can win with the extra knight, but it's super hard, and I've only seen other really strong players (above the 2200 level) win in that situation.

Seems like knowing how to draw this (i.e. knowing what to avoid) is a small but occasionally useful tool in your belt.

Mostly, but there are quite a few positions where the R+N can win.
Mate in 37 😮
[COMMENT DELETED]
I just played a game in which my oppent had the R+N and I had just the rook. My king was in the center of the board when the last peice besides the rooks and knight was captured - and there would have been no way for him to force a mate or a R for N exchange so it was drawn. If the defending king is in the center of the board it is extremely difficult if not virtually impossible to force mate. My oppenent did blunder though and I offered a draw before I forced it and that was the end of the game....
Nope it's a draw in general.

I'm sure this can be independently confirmed by someone with an endgame tablebase.
Good link!!
