Holding the Opposition a Pawn Down
Hold the draw against perfect play
Waking the engine…
The theory
The opposition is the tool that lets a lone king hold back a stronger force. Two kings a square apart, and the side not to move controls the ground.
Facing off. Answer each enemy king move by moving your king to keep the kings a single square apart along the same line. This denies the attacker any outflanking route.
Stay in front. Keep your king planted before the passed pawns. If you lose contact to grab material or wander, the enemy king marches around the side and promotes.
In this drill you defend against tablebase-perfect play. Take the opposition on every move and the half point is yours.
