Download link


Please don't mirror the download link, just send it to this page!!

Only Windows 64-bit with popcount and without it


What's new


Well this version was ready to release months ago but I just delayed thinking on formating and separating the code, but that will take some time so I think I will do it in the 0.4 version


  • Quiescent function now search all moves in the 0,-1,-2 depth and when in check
  • Forgot to write that in the 0.2 version I added stage move generation with captures ordered by MVV/LVA, now this is also in the qsearch
  • Keep repeating even in win positions but that is because the previous move made by the engine is not taken into account so that's why it repeats the position
  • Eval is still the same

Tests says that is ~100+ ELO than 0.2
