Two Knights Cage the King
White to play and draw
PlayYou cannot stop the b-pawn, so stop trying. Let Black have a queen and build a cage instead: your pawn wedges in front of the black king, the two knights wall it off, and a queen with no king to help it cannot win.

The theory
Sometimes the enemy king can be caged against the edge of the board. Without its help, even a queen may be unable to make progress.
Do not chase the pawn. The b2-pawn cannot be caught. 1.Nd5 threatens Nc3 and forces Black to promote immediately, which is exactly what you want: you get to choose the shape of the position that follows.
The wedge. 2.b6+ is the only move. It gains a tempo with check, plants a pawn in front of the black king, and leaves Black's own b7-pawn frozen behind it.
The wall. Knights on d5 and f6 supported by the king on e6 cover every square the black king would need to come round and help. A queen on its own has nothing to attack and no way in.
In this drill every move is precise. Build the cage rather than grabbing material, and the draw holds.
