King's gambit "weakly solved" by Vas. Admit it. This guy definately knows what he does Smile


Solved is the wrong word. Maybe the best move the computer could come up with is more like it. Smile


This whole thing comes down to the validity of the assumption that if Rybka scores 5.12 or more, it is a win with 99.99999999% certainty and that it follows that this happens to be the same certainty for the entire results.

I really have a difficult time with both those assumptions and I want to know how he came up with that value. This is about 1 in 10 billion positions! That means if you sacrifice a queen, or a rook plus a pawn or two that you automatically lose (except once every 10,000,000,000 times.)

I have to say that I think this is utter nonsense, my years of experience in computer chess and other games tells me that no matter what the "score" reported by the program (other than Mate) there are holes in the knowledge and search that can make this go wrong.


The number seems to be a poetic license picked in a conversation with a journalist, rather than a number you write in a paper. Like a teen ager saying I am super-hyper-duper-sure, so I am 99.9999.... etc.

The bottom line is, there is a 100% probabilities to reach a position +5.12 in rybka scale for black after 1.e4 e5 2. f4 exf4 3. Nf5 d6.

Or, this system returns
Code:
3... d6 :-) >+5.12

(I hope some people pick my joke)

Miguel


Yes, I see it...and why are people giving this article any credence??? I mean really... Embarassed

Laughing Laughing Laughing


I am not so sure you got my joke (the smiley output), only a Gaviota fan will get it, and there only very few.

Anyway, +5.12 I am pretty sure was an old Rybka bug when the output got stuck in that number. I do not have rybka but I remember the complaints.

Miguel
EDIT: A further article should refute this one because Be2 is loses based on an underpromotion Smile


I got it. But it would mean more for a fan.
