Jet5
Jet5 Chess plays quick random moves biased towards captures, queening, castling and good chess positions. It will grab a mate-in-one. Crazy, blitz chess—fun!
StockfishThe famous Stockfish 10 engine. Contempt 50 (max). Movetime and aggressiveness are randomised per move. Small opening book. Stockfish on Github
LozzaLozza is a chess engine written in javascript and with an ELO about 2400. Engine coded by Colin Jenkins, and based on Fabien Letouzey's "Fruit". Small opening book. Samey ... so I tried randomising Lozza's movetime/depth in an attempt to provide some variation in play. Lozza on Github
