I discovered today that a popular site for stockfish and matefinder compiles is actually shipping old/outdated code instead of what I maintain in my branch.

Thus, I will start providing a basic compile for people who are incapable or unwilling to compile matefinder on their own.

I will also start adding a bench number to my periodic merges and rare updates, so that people can verify their build is authentic should they so desire.

Link to git repo:
https://github.com/jhellis3/Stockfish/tree/mate_finder

You can also download the latest executable by clicking on "releases" on my github page.

Hi Joseph Ellis: is depth to mate syzygy on the implementation agenda?

Matefinder + dtm syzygy suit the engine.

Even if latest version is 5% faster than 2016 december version it is worse in finding (shortest) mate from Chest database. BTW what is clean search meaning?

Hi Joseph,

Any chance you can add a non-popcnt compile, for those who have an old processor ?

I would prefer BMI compile and shorter name like "SF Matefinder".

I can do that, but I draw the line there... no 32bit exes. I will add the exe to the release on github when I get a chance.
