My lockdown hobby was writing a chess engine, and learning Python and Rust in the process. Currently Odonata is available to play as a bot on Lichess, though Odonata only plays blitz and bullet games right now, as she's running on my media centre, and Netflix stutters if she's thinking too hard...
I started Decemeber 2020. Python and Rust are very different from Java, which I had programmed maybe 10 years previous. Certainly my first efforts at Rust are not very clean, clever or idiomatic, but the code improves as I revist areas to build improvements.
I'm aware that this is now yet another chess engine, with yet another set of Python bindings. In part this is because the project was intended as a learning exercise, but also there did not appear to be a Python native extension available.
v.0.3.26:
180 Elo improvement from 0.3.17
Futility pruning
Null move pruning
Multi-threading (still experimental)
Command-line switches for benchmarking and perft (use --help)
Bishop pair bonus
Json-rpc for python interface (still experimental)
Lockless transposition table
