How to kill Naum 4, playing you WITHOUT YOUR QUEEN !!! 2009

[bob]

It is much simpler than that. If a program does not have _specific_ code to help it avoid blocked pawn structures, a program will gladly gobble material and walk right into forced draws. If one plays enough on ICC, this problem becomes one that is recognized. I spent a lot of time working on Crafty to avoid this specific problem, which is no longer a problem today for it because of the eval changes to help it recognize that the more blocked the pawns become, the more drawish the position becomes, regardless of other considerations.

Not all programs are very good at this, as they are not developed in an environment where they encounter this problem with any frequency.

Thanks Bob for the statement....Can Pablo beat Crafty then
The answer is yes when cows begin to fly

[Damir]

do cows fly? I thought it was the pigs...

I won't go that far. It is very hard to block up the pawn structure, but then again it was also very difficult to beat Crafty with the infamous trojan horse attack by sacrificing a knight or bishop on the g-file. I fixed that only to lose when the opponent sacrificed a rook on the same file. I fixed that only to lose a few games where the same opponent figured out how to sacrifice a queen the same way.

I would never say a problem is fixed, just "improved".

In the movie "Twister" cows flew. So it will happen given the right weather conditions...

... in fact, there are cualitative victories, and clasical wars... What had sayed the population in 1915, or son, when the great Jose Raul Capablanca was over the waves on the sea, if one of the oponents of these that he had the costumer to offer a rock in advatage, If a simple amateur would had sayed to the World Chess champion, the great machine (for me a real paradigm)... "Mister Capablanca: ok take my Quen for your bishop, and one of my rooks for one of your knight", and then after the moves, the amateur won, and the Chess World lost...?
In fact that was the situation playing against the Naum 4 ... I won, a player over 3.000 elo....then I wonder... What the Math are ?

Wasn't a proper win though.

I could probably beat Kasparov with rook odds (ME playing without my KR).
(According to all this)

He's a hopeless case Graham,he's confused when it comes to this statement:
A stupid win on time because of a more stupid server software bug
