Zappa updated!

[Volker Pittlik]

Anthony send me a new version of his program. Also the book has been updated. This version works on my Athlon and I'm pretty sure it will work on others too. However, please make sure the program works for you before you download the 13 MB book.

Release notes:

1. Major bug in the book editor fixed; thresholding now works correctly.

2. Exactly the version that competed in CCT.

3. SHOULD work on Athlon CPUs. Should is the operative word here.

4. Definitely stronger than Zappa 0.8B2. I am not sure how much; my guess is 50 elo. But you guys would get bored without mysteries in life, wouldn't you? I am personally more interested in slow timecontrols, but feel free to test Zappa at any speed.

5. Consider this line an official request that Zappa be entered in any tournament available.

6. If config files show up in notepad without line breaks, open them with wordpad.

7. Have fun!

P.S. I'm not sure what should happen with the 64-bit version.

As far as I know Celeron A processors don't have SSE instructions which Zappa seems to use, so I'm afraid the only hope for you is that Anthony will make a compile for older processors.

Fantastic! - Well done Anthony.

Zappa now runs on my Athlon XP-M /WinXp.
Here's my little contribution to celebrate this
and your recent tournament triumph.





Thanks,

Jim.

[Igor Gorelikov]

I think by the above posts that the problem is related to Win98. Zappa runs fine under Windows XP.

However, please make sure the program works for you before you download the 13 MB book.

Speaking of the large book... any news on whether it has been fixed too?

One has reported a problem after download. I can't reproduce that.

It seems a bit strange that Zappa (using the big book) plays every time 1.e4 e6 2.d4 d5 3.exd5 (French Exchange) as White. This moves seems to lead to very drawish games.

Well, it seems that we Win98/ME-users are a suppressed minority!

Nevertheless, if I?ve to decide, whether to throw away my (since more than 5 years working) Win98 or this crazy Zappa, I?m sure you can guess how my decision will be ...

Regards,
Franz.

[Anthony Cozzie]

OK, CreateThread (which I am using) has changed since Win98. One of the parameters can be NULL in Win2000 but not Win98/ME/etc. This should be simple to fix. I'll try to get it done tonight.

Really, though, no one should use those operating systems. Win2000 is just SO much better . . .

Hi Anthony, it was me who noticed this, because I played a few Blitz
as Human vs. Zappa and may be I will even do a live Blitz match
against it, as long as Zappa always plays the French exchange vs. me.
I feel I have good chances then to win a 10 games match, when having
always Black

Will Zappa play with this book in RWBC?

Best wishes,

The public book doesnt play bad line at all. Zappa?s Books are based on nagged files and pgn files. If Zappa chooses the french exchange mainly (because it is not the only system against the french defense), Zappa statistics consider that exchange has a better overall in the pgn database used to create the book. Even though several moves are nagged with !!, Zappa prefers the move with the better statistics.

Additionally, Anthony requests me to use unusual openings in this opening book because he wanted to see the Zappa?s behavior in such openings, although we had run long tests with such openings.

The public book is optional and if you think, it doesnt fill your expectations, you have other options. Just a matter of tastes.

Regards, Arturo.

Hi Arturo, I have not said the French exchange is a bad line,
but it makes it very easy for Humans to make a draw and it is
one of the most drawish lines around too.
Actually I would always even try to win here for positional
reasons as Black and being a Human.
More important is that it is used as _only_ answer to the French
with 100% probability and it has not the best statistics as the
log from Zappa tells? Did I missunderstand you because it seems
you said something else in your message?
