Last time I did that, I suddenly started getting chess-related spam in my inbox. It took quite a while before it subsided...

Here we go for day 2, six games to be played today .. Rybka starts with the white pieces against Arasan, our first Caro, both sides out of book early with Rybka nursing a slight advantage ..
EDIT: Move 17 Arasan took what appears to be a poisened pawn on b2, I'm confident we should get a result in this game.
;)
EDIT: Arasan resigned on move 28

Hi Nick,
Great, give us an update here now and then :-)
Jeroen
Great, give us an update here now and then :-)
Jeroen
Will do - thanks for your support Jeroen, shame you can't get onto to ICC to kib the games!
Yeah, no free account anymore :-(. But when you score 14/14 this will do me good!
What book Rybka3 bets uses in this tournament? The one by Jeroen that will be with the official Rybka 3 release, the private book of Jeroen for tournaments, or another one?
![[de]](/mwf/v12/flags/de.png "Germany")
Nick is using his own private book.
how we see the games online?
![[is]](/mwf/v12/flags/is.png "Iceland")
Having a 2,5 point lead after 9 rounds isn't bad at all :) Besides winning all the games I like how Rybka plays.
2.5 points? Did HIARCS draw? :)
Yes, Deep Sjeng - Hiarcs was a draw.
Game 10 Freenzee by Sune Fischer is trying an Alan-esque opening on us, could be interesting ..
Any news? Ng4 looks a bit odd to me.
A bit odd? Looks like R3 was suffering from temporary insanity. Now if you told me this was in Nick's book, it would be much easier to believe! :-D (Just kidding Nick).

Alan

Hm, when I was browsing through some of your games, I noticed you also like to do a little bit of 'insanity moving' from time to time :-). Perhaps R3 was switched into Alan mode or something, can you help us out Nick!?
Well, yes, I must admit that my book has some really amazing trash in it. A few freestyles back, I did an experiment to see how well my engine would play by itself (just Rybka 2.2n I think) on a slower than average dual Opteron and book). The results were mediocre (3 wins, 2 draws, 3 losses). I wandered in during one of the games where I had white against Sebi and was a little distressed when my king moved to d2 for no obvious reason! Turns out, this has been a successful move from the early days of Fritz 7. Luckily my engine was playing against Sebi and managed to get an uphill draw. :-)
Anyway, I'd like to know the time and depth of move 6. Seems like a major meltdown to me.

Meltdown!? Well, in that case you could consider calling it 'the Chernobyl attack'. Or 'the Mugabe defence' :-)
Mea culpa. You can look into the kibitzing file attached to the post I made with a picture of the setup. You'll see Rybka kibbing 0-0 before Ng4 was played. The reason Ng4 was played was because Rybka went back into book and my book had (0-0) 67% and (Ng4) 33% and luck was not on it's side. There are a number of reasons Ng4 was in the book:
1. The base of games in the book were selected by Rybka
2. Unfortunately the first probe into the game happens at move 12 and this was move 6
3. The minimum number of games required for the move to be played from the book was zero, as the games are all pre-checked, this should be safe-ish. This Ng4 comes from a dumbo game between BBchess and Typhoon from CCRL, although where the moves come from shouldn't matter as Rybka checks all the games
There are a couple of fixes to this:
1. Add an initial game probe earlier than move 12, I'll probably do this anyway
2. Run with min-game 2, this is almost definitely what I'll do, this would have fixed the last draw also and given us more of a chance at 14/14
The trouble with min-game 2 of course is that it could lead to missing strong single-game novelties, min-game 2 (rather than min-game 0) changes the size of the Polyglot book from 240mb to 15mb ! I guess I'll just deal with those really strong single games in an overlay book.
Anyway, you'll be happy to know that Ng4 is no longer in the book, and Rybka was fortunately strong enough to win the game anyway.
PS. What is your view on 1 ... Nf6 in reply to 1. b3 in general?

Hey Nick,
I'm relieved to find out that Rybka didn't pick this bizarre move. I am always finding trashy moves like this in my book, but I assumed your book was better vetted. :-)
I've been using 1...Nf6 as my reply to 1. b3 for a while, mainly to try to prevent transposing into lines that I want to save for freestyle and correspondence games. Its played less than 10% of the time and in engine-engine games, black frequently follows with ...d5 and ...c5 transposing into much more common lines. Some of these lines lead to positions that Chessbase categorizes as A08 which Rybka 2.3.2a plays very poorly (you should see these in your database). White has to be careful in these lines not to rush c4 (as your opponent did in the tournament) hoping for e5 (but we already know that, right?).
Regards,
Alan

> but I assumed your book was better vetted
It will be :) I'm working on it but it's still less than four weeks old.
Thanks for your thoughts on 1 ... Nf6, I know you like zappa in these 1.b3 openings, I'm often amazed at how bad the eval is for white for such a long time, and then the true power of the white position is exposed moves 15 onwards. A good opening for Freestyles perhaps, at least in the qualifiers, to catch the engine jockey unware. Lately, in tuning this book in fact, I've seen a lot of games where white plays e3 rather than c4 and just gets rolled, so I'm not sure how early is early for c4.
I think many engines undervalue white in the beginning of the game because of the initial lack of white pawns in the middle of the board. Of course this is supposed to be temporary.
As far as getting rolled without an early c4, probably we should arrange a time to hash this out on the Playchess server :-). Against ...d5 ...c5 ...Nf6 I've had good luck with e3 or f4. I usually get away with g3 too, but it isn't really sound. With an early c4, black can frequently get immediate equalization or better by pushing to d4 (Zappa is more likely to do this than Rybka 2.3.2a).

Next up, chessthinker from Lance Perkins ..
When Rybka comes out of book I'll post the image ..
Sjeng(C)(64): chessthinkerx has a rotten position alreadyWhen Rybka comes out of book I'll post the image ..
Was Rybka out of book on move 5 already? 6.Nc3 is quite strange, and we all know how much Rybka likes this move. But on the other hand, the position after 5...Ne7 is very common?!
Yes this Ng4 is not in book, I guess I am a tad underbooked in these b3 lines.
I was talking about your game from the previous round. But you are right - Ng4 looks weird, too. :)
The correct response to 1.b3 is e5 or d5 at the moment .. easily fixed :)
Still interesting - though I don't know how broad your (?) book is. This position could occur via many different move orders. E.g.: 1.Nf3 Nf6 2.c4 c5 3.Nc3 Nc6 4.e3 g6 5.b3, etc. So I would have guessed that the position is still in the book.
By the way, the setup starting with Nf6 Rybka chose is very solid - white shouldn't have an advantage here, either. (After Ng4, I'm not so sure, however. :))

A very exciting game ... will follow up with moves asap
EDIT:
(John Timmel, USCF commentator for this event)
TimmelJ(64): Rybka jettisoned it's isolated qp on d6 ...following up with tactical justification..now Frenzee king runningEDIT:
TimmelJ(64): I predict 0-1 though...the pawns will roll(John Timmel, USCF commentator for this event)
Sounds good.
Rybka score just jumped to +4 then +5, we're going to do it.
EDIT:
I think that's a little early to say. Anyway, game still running.
EDIT:
TimmelJ(64): Rybka didn't even need it's pawns...the bare king was too much for W..0-1
TheGiver(C)(64): gosh... rybka is going to go perfect scoreI think that's a little early to say. Anyway, game still running.

Great! Any news about the places 2 through 5? How did Hiarcs, Sjeng and Diep do?

Okay, Thinker is next and then probably Crafty. I am enjoying this, some more nice games Nick!
![[in]](/mwf/v12/flags/in.png "India")
well played 14/14 would be very impressive
HIARCS drew Crafty too
6...Ng4? is a stunningly bad move, giving up two tempi for no obvious reason. Can anybody on the Rybka team think of any justification for this?

Please see my response to your other post on this
icc? playchess?
> Was Rybka out of book on move 5 already?
No, Rybka's first move out of book was 9. Be3, already with a strong position. John Dart (Arasan) was maybe expecting Rybka to play like a girl under 10 perhaps :)

Rybka with a nice opening advantage in the chessthinker game ..
EDIT: My goodness!! Rybka has sac'd a pawn on the Q-side and is going all out on the K-side - you have to look at the second picture !

TimmelJ(64): Rybka ready to steamroll chessthinker ...all for a measly pawn.
while our game against twistedlogic is not going too well :(
Don't worry, you'll do ok :)
thanks but very impressive, I saw you whisper that this is a version of a Rybka 3 beta ?
