[quote="Nimzovik"... It is simply pride of accomplishment. ....:[/quote] to win with a GUI feature again and again and again ...

The problem is the "again" part. Thats all!

[Graham Banks]

Hmmmm....... some of your assertions are assumed. Note also a time win is a win. That is why they have clocks at tournements ....yes? I fail to see the need for the animosity. His win does not take anything away from the engine or the maniacal fans of the engine. It is simply pride of accomplishment. Relax! The game does not necessarily prove anything. His style (as evidenced by many other games) of play -the stonewall - is really quite astute and fair in taking liberty with the machines rather blatant -shall we say -pernicious (?) - handling of positonal concepts. His style does indeed makes itself felt. Why not? Why not capitalize on the machines fallacious er....thinking? Should the human play the way a machine wants (needs ) it to play to fit some peoples definition of chess? Do not the machines take advantage of a human's fatigue and other factors? Ahmmmmmm? Perhaps Pablo is to the machines as Steinitiz was to the death of the 'Romantic' style of chess.

A win on time in a position that is not won on the board is nothing to be proud of. I agree with Damir on this.
I'd like to see some of Pablo's real wins.

[Nimzovik]

Au contraire Mr. Graham. A win with the clock is just as valid when one is losing on the board. The victor could easily claim that he was 'pressurizing' his (Pablos's) opponent (yes I know the computer has no personality to 'pressurize' however it does indeed have less time to think.) As far as seeing a 'win' of your description I do not recall Pablo winning. He usually attmepts to draw via fortresses and blockade. Repetitive some say? Yes....... IMHO I enjoy seeing Pablo tweaking the tail of the machines ad infinitum. Perhaps it just might induce the wizards of artificial intelligence to address these glaring positionl inadequcies and inspire a new paradigm of programs.. I being a positional player of the Nimzo school myself lament the pathetically woeful and brain damged assessments of the machines of such locked positions and other chess techniques... Truth in chess will not be truly complete via a machine until they encompass all aspects of the game.

[Werewolf]

Possible bug with Stockfish: I can't get it to take part in a tournament with other engines in the Fritz interface. Works fine in every other way.

[kurtneumann]

engine with future. still few tests only but good play.

This is a maintenance release of Stockfish 1.6.x series, you can download sources from here:

http://www.mediafire.com/file/y54mmw32hyw/sf_1.6.3.rar

It is 100% functionally and speed equivalent to 1.6.2 so there is NO ELO DIFFERENCE, so, as usual, testers do not need to redo anything.

The aim of this release is to fix all the reported bugs that have been accumulated in these weeks.

Code: Select all

So here are the fixes:

- Extend maximum hash size to 8GB (it was 2 GB)

- Fix a possible crash when using many threads (thanks to Bruno Causse for the fix)

- Fix en-passant parsing from fen string

- Fix various UCI interface issues so that now connection with GUI should be reliable with all the GUIs

- Fix compatibility with gcc 4.4

- Fixes a Chess960 bug when playing with more than one search thread

- Add hardware POPCNT support for gcc: use 'make gcc-popcnt' to enable hardware POPCNT support if you have an i7 / i5 CPU

- Fix sending of best move during an infinite search

- Optimized "Minimum Split Depth" for 8 cores and removed auto-limitation to 7 cores (thanks to Louis Zulli)

Thanks to the (many) people that helped with bug reports and testing.

Please Jim, could you be so kind to setup the binaries ?

Thanks
SF Team

[Hart]

I saw two SF crashes yesterday. I lost the PGN to the other one, but still have this. Let me know if there is any more information I could provide that might be useful.

Hello Joseph,

If you tried the link from above or start of this thread, those are only the sources from the Stockfish team. You will have to compile those yourself or just use the compiles from master builder Jim, for Windows or Linux. There is not supposed to be an elo increase with this version, but some bugs were repaired and it will run better if you have a machine that can use 8 threads. Jim Ablett's compile is already from a few weeks back, it's to be found in this thread or on Jim's site where you'll find the same link:

http://homepages.tesco.net/henry.ablett/jims.html

Regards, Eelco
