Depends on position, but normally a draw.
A Draw? King-Rook vs. King-Knight

It's against the rules of the site to talk about ongoing games. Decide whether to accept the draw or not and then, when the game is finished, post it and get others to comment on it.

jonnyjupiter, thanks and apologise.
Anyway I already decided to accept the draw... and I posted the question here since this game is on-going in another site.
Thank you, all
That position is a draw
Here is a good site to check stuff like this out after you finish games:

No worries. Since the game is now over I can comment:
King + rook against king + knight can only be a forced win if the knight is separated from the king or if the king is trapped in the corner, otherwise it is a draw. Your position was a draw with accurate play from both sides.
I'm playing a game where I have a knight and a rook. He has a rook only.
He keeps checking me with rook and trying to force a draw. Is this a draw?
This is on Chess with friends.

Why not try cover your Knight to the King, so the rook can't give check.
However, Bishop+rook+king vs king+rook is sometimes drawn.

The problem is i was playing a game in a few min ago i had rock and a king and black had king and a knight i kept checking him but they kept blocking it with there knight close to the king so i couldn't eat it we ended up with a draw cause 50 moves passed without moving any pones

When I have the knight in this endgame, I just keep my king and knight close together in the center of the board and wait until one of us runs out of time. Usually that's me though, because I'm playing on a laptop with a trackpad.
Emmanuel Lasker demonstrated an ending against his namesake Edward Lasker where a king and knight draws against a king, rook, and pawn.
I've been offered a draw in one of my games. I'm playing with only one rook and my opponent has only one knight... should I accept it?
No need to say that we've been playing around a couple of moves... I know I CAN mate him with my rook but the knight has been always bothering...
Regards!
