Queen vs. Two Rooks

I’m continuing with my articles about material imbalances. This time it’s queen vs. two rooks

What can we say about queen vs. two rooks? Using the beginner material scale, two rooks are worth 10 points, and a queen is worth 9 points. Does that mean that two rooks are better than a queen? If that were a simple question to answer, then I wouldn’t be writing this article…

Coordination

It depends, as usual, on coordination. Bad coordination, especially with more pieces on the board, is, in general, a recipe to disaster when facing the queen. The queen is a goddess at causing nasty cases of LPDO (loose pieces drop off). If the rooks are coordinated, however, then the two rooks can be an effective force.

Number of pieces on the board

Don’t underestimate the power of a queen and minor piece(s) combo. Those can be quite annoying, especially if the opponent’s pieces are badly-coordinated. The pieces can, of course, be cooperating with the rooks too, but usually it’s the side with the queen that is better off.

King safety

It would be criminal not to mention a thing or two about king safety, especially when we’re talking about queens. The queen has a reputation of mating unsafe kings, especially with the help of a couple pieces. And let’s not forget about perpetual checks; queens are good at that too.

I’m not saying that two rooks are not good attackers. No, they can be, but mostly when they are coordinated. “Ladder” mates exist, and two rooks on the 7th rank are true monsters. But the queen is generally better at dealing with weak kings than the rooks.

One thing that I should comment on is that, when looking up my games with the queen vs. two rook imbalance, I found that many of those were one-sided games, mainly in favor of the queen. It was not because the side with the two rooks botched it up but because the position was totally botched up to begin with.

Let’s look at a quick example of a position that isn’t one-sided.

White has a queen for two rooks, and there are a couple minor pieces on the board – if the minor pieces weren’t there, then black would just be better. The rooks aren’t coordinated for the moment, and white is threatening mate. Here, black should go 20…Ne8, defending the g7-pawn and preventing white from infiltrating on c7. The position there is roughly equal, as neither side can do anything concrete. Instead, I went for inspired active play with 20… Ng6? and was in trouble after 21.Qc7! grabbing some queenside pawns.

The rest of the game wasn’t pretty. I basically tried to blow open the white camp with active play, but everything was under control for white, and I was objectively much worse. I managed to generate something but in the process botched up the complications and would have been lost had my opponent found a nice little tactic. Fortunately, he missed that tactic, and the position went back to objectively drawn. Then, he blundered again, and I won. Phew!

What are the conclusions from that game? Don’t overestimate the power of the two rooks and don’t give away pawns unless you have a legitimate reason to!

Last October, I got a chance to get the raw deal: two rooks vs. a queen with equal number of pawns and no other pieces on the board. In simple English, I got the raw deal. And, in simple English, the game turned into a festival of mistakes.

Yes, I did use this game already in my queen vs. pieces article. This was after my messup that degraded my position from winning to better. So, what to say about this position?

The black rooks are coordinated, that’s for sure. There aren’t any loose pawns for either side, and black should be able to protect everything if necessary. The black king is defended by the rooks, though it can get a bit drafty (as it did in the game).

What’s the overall evaluation? Black is better, but he isn’t winning.

But how to try and win? The white king is a bit airy, but I didn’t see any realistic mating ideas. But how about the queenside pawns? None of them are really loose or anything, but it’s not a bad idea to eyeball them… In simple English, I needed to try to grab some queenside pawns without allowing a perpetual check. This wouldn’t be easy – I knew I had to resort to the old trade secrets of dancing around trying to make progress… AKA grinding.

Nothing particularly eventful happened for the next few moves, and we soon reached this position.

After having my rooks doubled on the f-file for the past few moves, I decided to try out the g-file with my last move 51… Kg7-h7!?, clearing the g7-square for my rook. I honestly doubt that the rook could accomplish anything effective there, but it was worth a try – I could always put my rook back on the f-file with no harm done.

Vincent had defended well up to this point, but here he cracked with 52.h4?. I thought this was a bad move but for the wrong reasons. Can you find the win for black here? I’ll come back to the solution later in this article.

I went 52… Rg7+? 53.Kh2 Rf2+ (going 52… Rf4 would have gotten there immediately, but I wanted to dance around a little) 54.Kh3 Rf3+ 55.Kh2 Rf4 56.Kh3 Rxd4

Yay! I’ve snagged a pawn! The only problem is that after 57.Qf8!, black cannot stop perpetual check. Oops… Instead, I got lucky when Vincent played 57.Qe5? which was the right idea but the wrong execution. After 57… Rd3+ 58.Kh2 Rf7, I stopped the perpetual. Still, after 59.Qe6, I had to figure out what to do. Black’s best policy is actually to give up the d5-pawn with 59… Rdf3 in some form or another to stop the perpetuals. Black retains some advantage there. I went 59… Rff3?. Here, white would have had a draw after 60.h5!, not letting black escape with the king via g6. After some thought, my engine gives triple zeros. Instead, Vincent couldn’t resist checking with 60.Qe7+?, after which my king successfully flees. The game continued 60… Kg6 61.Qe6+ Kh5 62. Qe5+ Kxh4 63.Qe7+ Kg4 64.Qe6+ Kf4 65.Qxh6+ Ke4 66.Qh4+ Ke3

All those checks may seem scary, but I was well aware that this was no perpetual. My king has run towards the queenside, and my rooks are now helping shield his majesty. This is the point where white starts running out of checks. A few moves later, I won.

I want to go back to the moment after 52.h4?, where I had a win.

Tsay8

Black should be concerned that his king doesn’t get into a perpetual check, but the winning move here is ironically 52… Kg6!. Black’s plan is simple: play Kg6-h5xh4. Then, white will be forced to trade his queen for black’s two rooks after Rf2+, resulting in a completely winning pawn endgame for black. How does white stop this? Well, he can’t! His checks are useless! I completely missed this remarkable idea, and kudos if you found it.

So yeah, queen vs. two rooks is not an easy imbalance to play… What’s the conclusion? I guess it is not to underestimate the queen – in their raw form, two rooks are better than a queen, but in many other situations they are not.
