Schedule

Round Times:  Saturday: 7:00am 9:00am 11:00am 1:00pm 3:00pm
                       Sunday:   7:00am 9:00am 11:00am 1:00pm
                       Blitz Tournament to follow regular event
                       Based on ICC's "date" command. (Time zone is EST)

Rybka @ CCT11

Nick is handling the opening book again, with a bit of help (I believe) from Jeroen and Victor and his Convekta gang.

Four octal machines (2 Skulltrail's @ 4 and 3.8 GHz, 1 Xeon X5460 @ 3.8 GHz, 1 x Xeon X5450 @3.6 GHz) and 5 Nehalem Quads (Core i7 920 3.9 - 4.1  GHz), so 52 cores. The octal machines have 8 GB of RAM each, the Nehalems 6.

Broadcast

All games are broadcast on: ICC. A free 7-day trial account can be obtained there. Trial accounts must use their client called "Dasher". Paid accounts can use various other clients (WinBoard, BlitzIn, Chess Assistant etc.). Once logged in type finger cct10  (it's true, =10) and +ch 64 for more info. For a list of computer games in progress type games *C-rSs. The id of the games is the first item in the displayed lines. Find the game you want to see and type "observe" followed by the id of the game, e.g. observe 1123.

Rybka's games are broadcast on the ChessOK Playing Zone, and you can also watch the games in your browser.

Thanks for starting a new thread for day 2 Dadi. 

Rybka and Fruit have 4/5 points chasing the leader Glaurung who has 4.5/5.  There are four more rounds to be played.

Round 6 we have black against crafty

1. e4 c6 2. d4 d5 3. Nd2 dxe4 4. Nxe4 Bf5 5. Nc5 Nd7 6. Bd3 e6 7. Nxb7 Qc7

I can't tell.  I guess the less you know, the more exciting some of these games are!
Parent - - By Mark (****) [us] Date 2009-03-22 12:09 Edited 2009-03-22 12:12
Eval is down to -.11, so Rybka is starting to recognizing a draw.

edit
Parent - - By Kappatoo (*****) [de] Date 2009-03-22 12:12
I think the eval is always from white's view, so actually Rybka's eval dropped.

Yep, I was getting it backwards...

Crafty is no match for Rybka. Either draw, or win.

I guess Rybka isn't using the 6-man tablebases?  I'm sure Crafty is.

No, Crafty is not using it.  Bob just said that during the game.

Ikarus is a pawn up, but Fruit evaluates itself to be better by +0,35. Though, strongly looks like a drawn rook ending.

Rybka(C) kibitzes: -1.00 21...O-O-O; depth 20; 15s;

Apparently Fruit scores inversely (plus means black is better??!), so the mistery looks solved.

I don't get it. Rybka is down a knight, with bad pawn structure... How could he say -1.00??

Oh... Sorry, didn't see that Crafty doesn't have 2 rooks... Stupid me. :)
Thanks,        SpiderG

Maybe because it's up a rook also ;-)

Not exactly down a knight.  Fruit exchanged rook for knight.
