Chess engine: BrainLearn 29 NNUE

BrainLearn - UCI chess engine
Rating Chess Engines Diary CEDR=3762

BrainLearn is a free, powerful UCI chess engine derived from BrainFish. It is not a complete chess program and requires a UCI-compatible GUI (e.g. XBoard with PolyGlot, Scid, Cute Chess, eboard, Arena, Sigma Chess, Shredder, Chess Partner or Fritz) in order to be used comfortably. 

Read the documentation for your GUI of choice for information about how to use Stockfish with it. 

v.29:

Aligned with Stockfish 17.

Fixed mcts.

Fixed persisted learning and added the experience book option and an utility for reset (to be done for old experience files) and display content given a fen.

Extended livebook to LiChess in addition to ChessDB.

Removed opening variety and replaced with variety which is now a combo with three values:

-off the default

-standard without loss of elo

-psychological more risky because with elo loss, but not as significant, useful for inviting the engine to a game with psychological/human sacrifices, i.e., strictly speaking, incorrect, but almost impossible to refute.
