Pawnstar, is a UCI chess engine written in C++23. It uses a bitboard board representation, a parallel alpha-beta search (Lazy SMP), a lockless transposition table, and a perspective NNUE evaluation. The engine is header-only — every class lives entirely in its src/*.h header as inline definitions, so only main.cpp is compiled and linked (each test/tool is a single self-contained translation unit), and the build needs no LTO.
Legal move generation runs at roughly 600 million moves per second on a modern laptop.
