A classic problem endgame: Queen and pawns vs two rooks and pawns.

  • 1. e4
    White: Ghost of a Duke (ca. 1700), Black: moonbus (ca. 1960); notes by moonbus.
    • 1... c6 2. d4 d5 3. exd5 cxd5 4. Ng1f3
      Caro-Kann Exchange Variation, designated B13. (4. c4 would initiate the Panov-Botvinnik Attack variation.)
      • 4... Ng8f6 5. Nb1c3 Bc8g4
        Black has several tasks to accomplish in order to equalize in this variation: one is to get the QB either well-posted or traded off, otherwise it will be trapped behind the Black center after … e6, which is inevitable.
        • 6. h3 Bg4xf3 7. Qd1xf3 e6 8. Bf1b5 Nb8d7 9. O-O a6 10. Bb5xd7 Qd8xd7 11. a3 Bf8d6
          Black's next task is to deny White control of the h2-b8 diagonal and thereby control of the black squares in the centre. It is also imperative for Black to prevent the encroachment of the White knight to either e5 or c5.
          • 12. Bc1f4 Qd7c7 13. Bf4xd6 Qc7xd6
            Positional assessment of the opening: Black has equalized, has good development, even control of the black and white squares, a solid center, and a safe haven for the king; White's control of the center is slightly less firm, and he must now decide where to place the rooks.
            • 14. Rf1e1
              Masters (I do not pretend to be one) would probably put the rook on d1, overprotecting the d-pawn.
              • 14... Ra8c8 15. Ra1c1 O-O 16. Re1e2
                Black was threatening to double the rooks on the c-file and then advance the b-pawn to drive the White knight away; a typical Caro-Kann attack pattern. White understandably wants to re-inforce the weak c-pawn, but this move will prove to be a lost tempo. The rook belongs on d1 to shore up the d4-pawn.
                • 16... Qd6b6
                  Black immediately exploits the awkward placement of the White rooks and picks up a free pawn.
                  • 17. Nc3d1 Qb6xd4 18. c3 Qd4b6 19. Rc1c2 Nf6e4
                    This knight is now the most powerful piece on the board and cripples White's maneuverability.
                    • 20. Re2xe4
                      White grasps a drastic remedy.
