Engine Depth
Engine Depth: A measure of how many plies ahead a chess engine has searched in its main calculation.
In-Depth Explanation
Depth is reported in plies, where one ply is one move by one side. Selective search means depth is not a uniform horizon across every branch. Higher depth usually improves reliability, but tactical complexity, hardware, time, tablebases, and the stability of the evaluation also matter.
