user25963: Stockfish, Alphazero, Leela chess zero, Komodo have elo above 3300. I need the names of some adjustable chess engines below 3000 level, from beginner level to Grand Master level (2800 to 3000 elo), like Shredder?

user825: A lot ... Pick your engine from the CCRL rating list: https://ccrl.chessdom.com/ccrl/4040.

user30545: I did some test on engines that support UCI_Elo option.
Sample engines that supports said option. There are others. The list below are tested on UCI_Elo 2300.
