Your Fish Just Isn't That Good: What is StockfishDev?
Hello everyone! This is less a post and more a collection of fun links.
The Stockfish project usually releases a new version (Stockfish 8, 9, 10) after about 50 Elo of improvement. But in the meantime, there is constant updating and patching and testing. So while your HomeFish sits unchanged for months, there is a 'development' version of Stockfish constantly improving. Usually we call it SFdev. Versions are numbered by DDMMYYYY, so today's is 15092019. These are all possible to download so that you have the strongest engine possible.
One disclaimer- rarely a bugged version of SFdev is built that leads to huge Elo loss. But that just adds to the excitement!
I could write a long post about the development process, but you're honestly better off just exploring a bunch of links.
So here they are. Enjoy!
