1 Q vs. 2 R

I like heavy endings, that is with queens and rooks. Not too many books deal with these types of endings, leaving the student with many questions unanswered.

 

 

Here is one type that interests me. It comes in form of a question.

 

 

Which is stronger in the endgame, a queen or two rooks? Here’s an introduction.

 

 

Let’s first look at four well-established guidelines for these types of endings.

 

 

(1) If the rooks are not connected, then the side with the single queen has the advantage.

 

 

(2) If the rooks are connected, then that side has the advantage.

 

 

(3) The advantage always lies with the player who has the initiative.

 

 

(4) Having the advantage that does not mean that side can win the game.

 

 

Here’s the first example.

[White, with the single queen, is the one with the initiative but cannot break through the Black’s defence. Neither side is in real danger as Queen versus two connected Rooks endings, with nothing else on the board, are almost always drawn.]

Adding a single pawn to either side obviously increases the chances for that side. The plan should always try to push the pawn towards a promotion.

 

Adding two isolated pawns to the side with the Queen, the result is almost always a win, even without a promotion.

With two isolated pawns with the two rooks, a win for that side is the most likely outcome. But examples are hard to find. We’ll cover more in a later post.
