Starzix is a strong C++ chess engine that communicates using UCI.

The search is a standard fail-soft negamax principal variation search with various enhancements such as alpha-beta pruning, quiescence search and transposition table.

For evaluation, it uses a (768x2x6 -> 1536)x2 -> 1 horizontally mirrored NNUE trained on Lc0 data with my trainer Starway.

Have clang++ and run make

• Hash (integer, default 32, 1 to 131072) - transposition table size in MiB

• Threads (integer, default 1, 1 to 512) - search threads

• display

• perft <depth>

• perftsplit <depth>

• bench <depth>

• eval
