        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.

          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.

            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.

              White offers the h-pawn in exchange for active piece play.

                So far we have duplicated the game Ruslan Musalov [2399] vs Nikolai Shukh [2438], 2011 Russian Chp.

                  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.

                      White has now accomplished one part of his task: he has undoubled his pawns.
