For chess engines such as Stockfish to beat weaker opponents, you would want to turn up the contempt parameter.[1]

To be able to do this, you would want to use a UCI-compliant chess GUI such as Cute Chess.[2] It lets you change the command line arguments you use for your engine, and you can play Human-vs-Human, Engine-vs-Engine, Engine-vs-Human, etc.

Contempt was removed from stockfish 12 due to NNUE being patched in. You’ll have to use stockfish 11 or another engine to use contempt.
