THE STORY BEGINS

Every piece has a part to play.

At the 2014 Olympiad, Carlsen’s Scandinavian Defence leads to a queenless position in which White has a strong-looking knight on d6. Black works against its pawn support, centralizes another knight and eventually creates an advancing d-pawn. Study the changes in support before judging the outpost or the final material count.

f6 challenges the support of White’s advanced knight. White can recapture after the pawn exchange and keep a pawn on e5, so the outpost does not disappear immediately. Black must follow with useful piece moves. Compare the open file and the revised pawn support instead of expecting one pawn advance to solve the whole position.

Nd5 offers a central exchange that changes Black’s pawn structure. In the game, the bishop takes the knight and Black recaptures with the c-pawn. That leaves another knight to work around the centre and gives Black a d-pawn. Reassess the resulting files and pawn targets after the exchange.

Nxe5 removes a central pawn while the king is active. The capture is part of an ending with rooks and knights, so checks and pawn races still matter. Compare the white rook’s activity with Black’s central king and remaining pawn structure. The useful question is what each piece can do after the pawn disappears.

d4 makes the central passer an active source of counterplay. White’s rook and knight have threats of their own. The recorded continuation includes checks, another pawn advance and a knight exchange before the king joins the ending. Calculate those transitions rather than declaring a passed pawn decisive merely because it is advanced.
