Thanks for the repeated kindnesses.

But the human had _every_ reason to play for a draw in this game.

Super-GM Adams is now rated almost 25 world-ranks and almost 50 ELO points
higher than K, and Hydra recently mauled Mickey 5.5 - 0.5 in a similarly
time-controlled event. And it wasn't that Adams didn't have much financial
incentive to do better.

So K. would be right to seek a draw except from certain types of unusual or
clearly won positions; he would be crazy not to do so.  Hydra's abilities are to
create tactical complications where there don't seem to be any possible (not cf.
Aljechin), as happened when Adams too unsuccessfully tried to play somewhat
anti-computer.

Also K's ~400 ELO lead over you (corresponding to percentage expectancy of 92%
by traditional means, maybe 89% by Sonas's proposal) makes me willing to first
consider that RK is right and MD is wrong when you are saying opposite things.
:)


>He got an excellent position


Sorry, I do not see that.  I see a semi-closed position with statical
possibilities of an obvious K-side break by B or a technically harder Q-side one
by W, or both.  To consider  Black's position as excellent (in terms of
winnability; drawability is not at issue) is IMO incorrect and unsupported.

In another thread I discovered you have written your prescription for
Kasimdzhanov from 26. onwards...  I reply to it (soon) there, in-

I hope for a lively but polite exchange, thanks, and we can settle this OTB
instead of with epithets and adjectives. :)

I'll give you plenty of chessical bonuses there.

If you asserted that black has nothing to fear on the Q-side, and you did this
without any analysis, I do not know what to say.  The position is not
closed/locked on the Q-side!  But this duel is better moved OTB, I am sure you
agree. :)

Now, this is ridiculous.  I took the line chosen by Kasimdzhanov and showed
that, contrary to the claims of many, the position was dead even and the danger
as such was to white.  It is all around-
http://www.talkchess.com/forums/1/message.html?463219

Please make OBJECTIVE COMMENTS on SPECIFIC MOVES.  Say (like I did with
Uli's/Fruit's wrong analysis) - but here, if instead B plays this, white must
fight to get the draw, or specifics like that.  Long computer analyses with the
first few moves in sequence plausible but then a bad choice of course is
unacceptable, that was the undoing of Fruit's analysis.

I grant you advance victory in all matters involved with insulting, deriding,
making claims w/o evidence or proof and so on, so please - please SPECIFIC
REBUTTAL to what I wrote in-
http://www.talkchess.com/forums/1/message.html?463219
and which you again dismiss. You have called me a "loudmouth", an utterer of
"nonsense" and even an "idiot", so I will be pleased to get something of
substance if you know what I mean.


> This wasn´t a correspondence game,


If you think Kasimdzhanov embarked on Ka-g8 without seeing all (or at least all
the important) things I showed in-
http://www.talkchess.com/forums/1/message.html?463219
and much else, you greatly underestimate the level of chess at which super-GMs
participate.
My analysis took minutes only, and I am no K!
No correspondence GM level logic is needed, just 40/2 super GM logic will
suffice.



>it was an OTB game and the human once again failed completely after he
>unnecessarily opened the position.


The human failed to draw solely and only because of a temporary delusion by K.,
allowing the enemy rook into the seventh and freedom for the enemy N that had
been so carefully lured to a7. :)

The delusion is not caused by the preceding move sequence. But I concede the
opportunity for such a delusion would be less or nil in a semi-closed position.
