Using a reverse slope and an exposed flank as bait

After the opposing army divides, the defending force takes a central hill position with many troops just behind the crest. The reverse slope denies the enemy artillery a clear target while keeping those troops ready to meet the advance. An apparently weak flank is left exposed to channel enemy cavalry toward a predictable point. The exposed infantry form square when the cavalry moves to flank them, buying time for reinforcement. Terrain, concealment, and a deliberately inviting weakness all shape the opponent's choices in the resulting game battle.
