This is a small sample of Lua based chess to run from command line. 1. GarboChess.bat - good port of chess engine to Lua (ported from javascript) 2. fruit21chess.bat - good port of Fruit chess engine to Lua (ported from C++) 3. EmulatedOliThink.bat - kind of scientific port of a 64bit chess engine. NOT a useful Lua chess AI. Anyway, interesting to see checkmate at the end:) 4. c0_chess.bat - a lua library for chess 5. sargon.bat - Sargon assembler code of 80s ported to lua history at wikispaces chessprogramming about Dan Spracklen Just fast and simply positional. Not strong, improvable. 6. LuaJester.bat - Very good chess program for 32-bits, and fast. Almost best what lua can perform. 7. OwlChess.bat - a port of an old '92-95 Owl Chess program in Borland Turbo C (from javascript port). Good and well documented. It was written when no 64 bits seemed useful. :) This version sometimes crashes on LuaJIT. Other: --------- 1. polybase.bat - a polyglot book reader sample 2. abkbase.bat - an Arena book reader sample 3. pgn2js.bat - prepares pgn file to .js, see samples at https://gitlab.com/chessforeva/pgn2web Also lua to loadfile: --------------------- i64.lua - emulated 64bit variables to get working (1<<63) noBitOp.lua - can be used instead of BitOp (but slower) c0_chess_subroutine.lua - chess logic, not a fastest code Updated 2021.jan.
