The new chess engine Neuromancer 1.0 is an interesting proposition for people who want to play with a computer partner of the strength of an average club player.
The author of the engine is a programmer with nickname mateog03, who writes about his engine like this:
(...) I expect it to be at least 1650, maybe more.
It is original, quite short (less than 1300 LOC) and written in C++20 for portability (you need the pthread library though).
it's a classic alphabeta engine with an evaluation that consists of only mobility and king safety. it compensates the lack of features with speed and sometimes it draws completely winning positions by repetition, so there's that.
