Karjakin-Topalov, Corus 2007 round 3.

Clipping analysis from Rybka (2.2n2) is hard because the first line is 
(re-)computed almost immediately after the previous depth ends, not
the noticeable pause at "12/12", "13/13", etc. that I had with Fritz.
SINCE confederate cheating is specifically alleged, and since 
single-line mode on Rybka would go quickly up thru "depth 16" = the end
of the 15-ply round (2min. on my laptop *with* hash from the previous move,
so I guess 1 min. with better hardware, but up to 2 minutes again 
since real-time game running doesn't have as much hash advantage as my
longer testing runs), I've added the 15-ply round to my 11-12-13-14
style of Elista runs.  And I still often show the 16-ply round too,
i.e. go out to "17".

Since this is where Danailov reappeared for the rest of the game, I will
do the full 10-line methodology.  Also curious to see this move
from a *cold start* with 5-lines again:

do a *single-line* test of move 28.  Move-27 cold start:

Ah, rather than a switchback from ...Qc6 at 12 to ...Rb8 at 13
then ...Qc6 at 14, just a changeover at depth 12.  But since that
takes just 14 seconds on my 2-yr-old lappie, I gotta think
28...Qc6 would have been the choice if cheating were done with Rybka.
The overall confirmation makes me more comfortable with 10-line mode...


Now into 10-line mode for the "Main Event":
(cold start at 27 first, to fill some hash)


12, i.e. end-of-round 11

[missed 1st line of 13, but when it comes so quick, I don't think the
eval changes much.  Getting 11 would have been tough, another reason I

Weird swing, and 36...Bh6 came too quick for me to catch at 16, but it was
definitely first.  So:

Silly---I computed first 4 lines of the 17th round too but forgot
to clip.  They had 36...Bh6 at 0.96, 36...Ke7 at 1.13 I think.

display 0.00 on the /first/ repetition.  So this is a non-event.
