Work out which spots the enemy can reach before the player does

An ambush, a raid on a pickup or a retreat to a safe door all depend on one question: who is faster to this spot? Here is how to mark the cells that belong to the enemy, how different speeds change the picture, and who wins a tie.

Why this works

Whoever arrives first at a spot owns it, and arrival depends on speed as well as distance. Turning both walks into times and comparing them gives one picture that answers ambush spots, races for items and safe retreats alike.

When not to use it

It assumes both sides walk straight to the spot at a steady pace. If the player can dash, teleport or change course to bluff, the picture is only a rough guess. Treat it as a hint and add a margin, or watch the player's movement.
