Can highly recommend this article. I wrote a small chess engine for fun, mostly during a long plane flight back in 2018 when I had no internet access.

My process for writing the engine followed almost exactly the series of steps laid out in this article. The key improvement that I made was to add quiescence search with null move pruning. After I added that, it became quite tricky to beat (for my ~1450 lichess rated self). It definitely results in an engine that is extremely greedy, and almost anti-positional, but very tricky to prove wrong.
