It depends on the position and whether any pawns are involved. You have to be more specific.

It's 9 vs 10-meaning, queen is worth 9 points and rooks are worth 5 each (so 10 total).

Some factors to consider-the queen is more mobile, but rooks can work together (slower, but you can trade a rook for the queen and still win with a k+r v k.

I would prefer rooks because I can only really win or draw, but with a lone queen I can only lose or draw. These are assuming that you play them right.

I'm referring to just the pieces. No pawns involved. As far as position goes, who knows ( I don't). Most people I've talked to say the two rooks have the advantage. But with the diagonal capabilities of the queen I'm not so sure. I'm thinking whoever makes the first tactical mistake loses.

It's a clear draw. The side with the two rooks connects them so that the other king can't get past, then shuffles his king around and the queen can't mate on its own.

The side with the queen can't do better than repeatedly checking the other king, and can force a draw by doing this.

Hm. Euwe's end game book (old, but still) agrees with the draw, but disagrees with the "clear". He claims that it will usually be a draw, but the chance of a win is greater than with most other "equal" end games.

He agrees that the normal case is a perpetual by the queen, but positions on the edges can turn fatal for both sides, and unless there is an immediate win, the queen must consistently play for a draw or risk losing.

With no pawns and starting from a position were there is no forced win
then it should be a draw.
The Rook player has to avoid losing a Rook to a Queen fork and the
Queen player has to avoid getting his Queen skewered or pinned to the King.

However it all depends on who is playing. 😉

On my 1.2 Million -1400 DB the bare K + Q v K + RR has appeared 7 times
and all have been drawn.

Spammer - Pauline Calf RHP 2007 Game 3787485 is one.
Play out the game from move 54 and see if you can see White's missed win.

Add only pawns and the -1400 DB gives an edge to player with the Queen.
Games = 2914
Queen Wins = 1304
Draws = 695
Rooks win = 915

57 Rh8+! Qxh8 58 Rh3+ skewering the Queen


That took embarrassingly long to find.

That's it.


White played 57.Rg8 and the game was agreed drawn a few moves later.
Instead 57.Rh8+ wins.

And once again it is obvious why I will never be a good chess player.

I found
Rh8+
as the obvious move. Then I spotted
Qxh8
as the obvious defense, and never even bothered too look any further. I never even considered
Rh3+
.

If this has just given someone an idea on how to beat me... tough. Maybe it'll teach me.
