    Spanish Exchange Variation, C68.

    This opening leads to an early endgame in which each side has a clear objective: White will play to accentuate his king-side pawn majority, Black the queen-side. There are two main strategic considerations: 1) Black has the bishop pair, which is to Black's advantage. 2) White's pawn structure is sound and his 4 king-side pawns can break through against Black's 3 pawns, whereas the Black queen-side majority is hobbled and cannot break through due to the doubled pawns. Black must therefore either a) undouble his c-pawns, or b) break up the White queen-side with pieces. The chances are reckoned to be even.
  • 8. Bc1e3 O-O-O 9. Nb1d2 Ng8e7 10. O-O-O Ne7g6 11. Nd4f5
    This presents Black with a dilemma: either give up the bishop pair by exchanging on f5, or submit to backward development, since the dark-squared bishop cannot move so long as the White knight occupies f5.
  • 11... Bd7xf5 12. exf5
    This ruptures White's king-side pawn majority; so now, both sides have much the same task: try to undouble the doubled pawns, &/or break up the opposing side with pieces.
  • 12... Ng6e7 13. g4 Ne7d5 14. Rh1e1 Bf8d6 15. Nd2e4
    White offers the h-pawn in exchange for active piece play.
  • 15... Bd6xh2 16. Ne4g5
    So far we have duplicated the game Ruslan Musalov [2399] vs Nikolai Shukh [2438], 2011 Russian Chp.
  • 16... Rd8d7
    At this point, Shukh played NxBe3; the game went on to 78 moves with White eventually winning a difficult K&R vs K&N ending. My opponent, AppleChess, diverges here, so we are out of the book from here on.

    Forcing the Black knight to move, allowing White to exchange rooks, and forcing Black to advance the f-pawn (or lose it outright). This will create a weak square at e6, which the White knight will occupy and from which it cannot be budged.
  • 17... Nd5xe3 18. Rd1xd7 Kc8xd7 19. fxe3
    White has now accomplished one part of his task: he has undoubled his pawns.
