SF6 has been released

[Uri Blass]

Congratulations! I think it is an important achievement. I believe in the idea of cooperation for the sake of advancing science without concern for monetary gain. It is, IMHO a high expression of the best of what we aspire to.

Thank you so much for your hard work! I love chess and computer chess holds an unending fascination for me. So you have made this old guy happier today.

I wish continued success for the whole Stockfish team. Also, kudos to all the testers who freely contributed their time and resources to the project.

Very nice!

I do not think that the target of the stockfish team is to advance science(otherwise instead of only trying to improve stockfish they can do tests to find out what are the main factors that help stockfish to be strong).

It can be done simply by removing every piece of code that does not give a significant elo gain and see what we get.

It is possible simply to test every code that we want to remove
with SPRT(-6,0) at 1 minute per game and remove it if it pass the test.

I guess that the final result is going to be weaker than stockfish6 but still better than stockfish5 and we may know better what are the main factors
that help stockfish to be a strong engine.

SF6 has been released. Key features:

* Support for syzygy tablebases
* ELO improvement, around +50 ELO in self-play against SF5

It will likely take a few days to prepare the official binaries. Meanwhile you can either download a version compiled by abrok.eu or compile it yourself:
* http://abrok.eu/stockfish/
* https://github.com/official-stockfish/Stockfish

On behalf of all Stockfish developers and contributors,
Joona Kiiski

Excellent news and many thanks !)

Greetings,

Why no 32-bit this time? Thanks for the great work by the way.

Thanks to Daylen, official binaries are now available for download in:
http://stockfishchess.org/download/

We expect these to be somewhat faster than the ones abrok.eu is providing. However there should be no need to restart test runs or anything like that if you already have used abrok.eu compiles.

hi. the official android version(sf 6 JA) is based on arm5 compile from JA so its slower than arm7 compile,any date for arm7 compile?

You can try this version: https://dl.dropboxusercontent.com/u/896 ... ish-arm.gz. I don't know it if will become the official version. On my HTC One it is about 20% faster than the JA version.

The official android download has been updated now, so no need to use my link anymore.

Any word on when the iPad (IOS) version of Stockfish 6 will be released through the App store?
