stockfish 6

[ornicar]

A new version of stockfish is out! How difficult would it be to upgrade this fork? I honestly have no idea.

I think it shouldn't be difficult; I've been trying to reconstitute my development environment (I'm migrating and upgrading my development server) for the past month and I'm getting close to a point where I can do this!

I think it's just a matter of pulling/merging changes from the master repo; there's a merge conflict so I need to do the pull/merge on a development machine and then sync GitHub with that machine. I've tried to do this pull/merge before and found command-line git confusing, but in theory it should be simple...

Hey guys, I went ahead and did the merge on my fork.

There were some tricky parts to the merge conflicts, but in all cases, I looked at the git blame where @ddugovic had made the original change to figure out the intent, and did the sensible thing (I think).

Everything seems to work correctly, although I don't know how to test lichess KOTH-functionality specifically.

Hopefully this makes your jobs a bit easier :)

[ddugovic]

Excellent!! I'll test out your fork tonight and very likely pull your changes! :)

It now occurs to me that the simplest regression test would be to play against itself (SF5 versus SF6) via an interface such as XBoard or Arena Chess Interface! I look forward to doing that!

Thus far I've confirmed that with @apetresc's latest changes, Stockfish recognizes the game end condition. I'll review the code changes to ensure things look sane, then pull the changes.
