New version chess engine: Lynx 1.0.0 (Windows, MacOS, Linux)



Lynx it's written in C# (.NET 6). UCI protocol is needed.
Chess Engines Diary Rating CEDR=2672

Lynx release artifacts are self-contained and require no dependencies to be run.
However, you can also choose to build Lynx yourself.

Requirements
NET 6 SDK. You can find instructions about how to install it in yo

v.1.0.0
  • Getting out from ZeroVer club now that these two conditions are met:
  • Lynx has basically reached feature-parity with BBC, engine outcome of BitBoard Chess Engine in C YouTube playlist that helped me the most during the initial phases of Lynx development.
  • .NET 8 GA has been released and therefore Lynx no longer relies on pre-release SDK or library versions.
  • 🔍 Rewrite NMP
  • 🔍 In case of 'ponder-hit', research last depth
  • 🔍 Don't clear TT move if no best move is provided: keep old one II
  • ⚖ Use PSQTs tuned without explicit piece values
  • ⚡ Incremental move sorting
  • ⚡ Avoid checking lack of material in static evaluation when the phase is high enough
