Lua chess engine

Note: Lua 5.1 requires a pre-installed library for bitwise operation support - as BitOp. Lua 5.2 will contain it all by default. In fact, You just have to copy bit.dll to Lua folder.

Other Lua sources: c0_chess.lua - code library for chess logic - chess board, moves, short opening base, PGN and FEN functions, fischer-random, samples at online compiler site jdoodle.  Other sample is ShiVa project, chess logic without chess engines.
As always, it is better to use opening base, if there is a variant for given key, and the chess engine - after.

This pinky chess project uses lua chess.
