♡ 26 ( +1 | -1 ) two rooks versus queenUnder what circumstances would you exchange a queen for two rooks and vice-versa? In a recent game I had the opportunity to force my opponent to lose his queen in exchange for my two rooks, I didn't in the end as there was no obvious strong attack to follow up with.

♡ 204 ( +1 | -1 ) The value of queen versus 2 rooks ...... depends very much on position. Generally, though, I've found that the situation is at the outset hard to judge. In a pure Q plus pawns vs 2R plus pawns, the queen needs the extra pawn for "equality". Maybe. Here's a game I played (as Black) several months ago that led to just such an ending. I've set the opening diagram several moves before the ending arrived, as the sequence is full of incident b Black had given up 2 pawns already - not altogether voluntarily - but has every piece aimed at White's king. 23...Qa3ch 24.Kb1 Bxb3!! 25.cxb3 Rxb3ch! 26.axb3 Qxb3ch 27.Kc1 Bxc3 ... Now, 28.Nxc3 Rxc3ch 29.Qxc3 Qxc3 leads to something not too dissimilar from the game continuation, but White has some shots of his own up his sleeve... 28.Rd8ch!! Kg7! 29.R4d4! Rc5! 30.R4d5 Rc4 31.Qxc3 Rxc3ch 32.Nxc3 Qxc3ch ... Now we have the 2R vs Q ending. How to assess? I thought Black had whatever winning chances were going, but couldn't believe they amounted to much... w 33.Kd1 a5 34.Rd2 a4 Just how do you stop the pawn?? 35.R8d3 Qb4 36.h3 a3 37.Ke2 Qe4ch 38.Re3!? Qc4ch 39.Kf3 a2 40.Rd1 Qc6ch! Beginning a remarkable zigzag manouevre to relocate the queen... White has little choice in his available options. 41.Kg3 Qc7ch! 42.Kf3 Qb7ch 43.Kg3 Qb8ch! 44.f4 ... At last White realises that the king cannot return to f3. 44...g4! 45.Rf3 gxf4ch 46.Kh2 ... The pawn is taboo: 46.Rxf4 Qb3ch picks up the d1-rook. 46...Qb2 47.Rff1 f3 It seems already clear that Black has all the play... 48.Rg1 Kh6 49.Kg3 fxg2 50.Rge1 Kh5 51.Rc1 f5 52.Red1 Kg5 53.h4ch Kh5 54.Ra1 Qb7! Of course, the a-pawn is still under the queen's protection: 55.Rxa2?? Qb3ch 55.Kh2 Kxh4 56.Rxa2 Qf3 57.R2d2 ... Just about the only defence against 57...Qh3ch. 57...Qf1! 58.Rxg2 Qxd1 ... and Black won (59.Rf2 Qg4 60.Rg2 Qxg2 61.Kxg2 Kg4 0-1). The win proved surprisingly easy for Black. If White can save the game, it must be by adopting a different course of action early in the ending. Can he manouevre both rooks safely behind the a-pawn, say? Cheers, Ion
