According to the Turfgrass Management Manual, what distinguishes a "strategic" hole?

A strategic hole is recognized for being perceived as difficult by players, which stems from the design features that require thought and skill to navigate successfully. This perception of difficulty can arise from various elements such as the placement of hazards, the shape of the fairway, or the positioning of the green, all of which challenge a player’s strategy and decision-making during play.

While options such as featuring water hazards, being located in a scenic area, or being the longest hole on the course could contribute to the complexity of a hole, they do not inherently characterize it as a strategic hole. A hole can be scenic or lengthy without necessarily providing the tactical challenges associated with strategic play. Therefore, the defining factor is the players' perception of difficulty, which highlights the need for strategic thinking on how to approach the hole effectively.
