You may have better luck asking this at the chess stack exchange (https://chess.stackexchange.com/)

If you include endgame table bases, that probably makes the number rather large.

@acccumulation you right, I am interested in stats that do not reach endgame tables.

(Asked by: username_0 on 2022-12-20)

I'm looking for some **reference** for the number of lookahead steps typically used by chess agents (Stockfish / Leela Chess Zero / others?)

From a quick search I found that:
the answer depends on:

1. complexity of position,
2. computer hardware/processor speed,
3. efficiency of software/graphics interface,
4. time given to the chess engine.

with somewhat mediocre hardware a **depth around 15 ply's in one second** is typical.

the NPS value for the Stockfish engine: 49,473 kN/s (calculating 49,473,000 positions (nodes) per second).
