Redfish (with reference to the popular stockfish project) is a chess engine that I created out of interest for game theory and to strengthen my C++ programming capabilities. It uses a combination of 0x88 and bitboards as board representation, alpha-beta-pruning as search algorithm on the tree of possible game states and a simple piece-counting evaluation function.

Building & Running

make -j

Apart from gcc and libc there are no external dependencies.


  • Implement casteling, en-passent pawn-captures and 50-moves-rule
  • Implement pawn replacement
  • Validate pawn movements as there seem to be some bugs
  • Parallelize search algorithm (OpenMP/MPI/OpenCL)
