The Knight Blockade
Hold the draw against perfect play
Setting up the board…
The theory
Knight versus passed pawn is the purest test of understanding the knight: slow across the board, magnificent in a two-square radius.
The blockade. A knight parked in front of a pawn is immovable perfection: it can be attacked but never chased profitably, because it guards its own square by definition of sitting on it... until the king comes. The real technique is what happens then: the knight steps away WITH TEMPO (a check or a fork threat) and returns to the blockade the next move. This loop holds against any non-rook pawn from almost any distance.
The famous exception: rook pawns. In the corner the knight runs out of hopping room: a knight blockading on a1/h1-adjacent squares can be zugzwanged. Against an a- or h-pawn on the seventh with the king close, even the loop fails.
In this drill you hold a centre-pawn blockade against a perfect king escort. Any hop that loses the loop's rhythm and the tablebase converts instantly. A wonderful way to internalize which squares a knight really controls.
