Stockfish Alternatives

Stockfish reviews and mentions

• I can draw Stockfish and so can you
  1 project | /r/chess | 7 Mar 2023

  drawMe branch: Stockfish will internally enable multiple lines in the opening and choose a suboptiomal move. This makes it harder to prepare against a certain opening and use memorized lines. This modification will certainly lose elo against the current Stockfish.

• Will the best chess engines really beat the best players 100/100 times?
  1 project | /r/chess | 7 Mar 2023

  This is not a new debate and even Vondele (the main stockfish maintainer) has made some versions of Stockfish that try to play bad moves in the opening to avoid those memorized lines and even a version that scores draws as +0.25 to try to avoid them.

• Stockfish's search tree trying to find a mate in 2 visualized
  2 projects | /r/chess | 3 Jan 2023

  The original idea was by Vondele back in 2017. This version outputs the code that graphviz uses directly to the console but it begins with xxx so it can be filtered.

• Are there any chess engines with customizable evaluation functions?
  3 projects | /r/chess | 12 Jul 2022

  https://github.com/TheBlackPlague/StockNemo, eval function is 76 lines of code. and simpleeval https://github.com/vondele/Stockfish/tree/simpleEval a modified version of stockfish which just uses piece value as an eval function (1, 3, 3, 5, 9)

• Tactics are important - but how much so?
  2 projects | /r/chess | 22 May 2022

  That's what I get for only skimming the file, I guess they left the fancy code in place and just returned early. Found the commit.

• What makes SF15 better than 14? I mean, what do they do/program to improve performance?
