Kb6 sends the black king toward the queenside, leaving the opponent six possible replies.
c4 is White’s answer, pushing the pawn forward on that flank.
d4 advances the central pawn, reducing White to only five legal moves.
In the real game, the player did find Kb6 and then d4, eventually winning when the opponent resigned. This pawn endgame shows how crucial it is to activate your king on the right side before your opponent does.
The French Defence, played here in its Exchange Variation, has been one of the most studied openings for centuries among players of every level. To train on this kind of pawn endgame, browsing the wooden chess pieces can help you picture each square of the plan.
