The theory
Rook plus knight against rook is one of the standard 'extra piece, still a draw' endings: the knight is too short-ranged to build a mating net with the rook against a careful king.
The method. Keep your king in the center or near it, away from the edge and corner where mates live. Keep the rook active, checking the enemy king and standing ready to trade into a dead-drawn rook ending or rook-versus-knight.
What to avoid. Do not let your king get driven to the edge and boxed in, and do not shuffle passively: give the stronger side no target, and the half point is safe.
In this drill you defend with the lone rook. Stay central, stay active, and steer toward a trade: the tablebase attacker cannot force a thing.
