Nope. 3000 cores IBM cluster working on it for 4 months where all positions with +5.12 are discarded. With an assumption that those are practically won with more than 5-sigma (margin for a discovery I think). Quite an achievement IMO!
P.S: I was actually looking for April Fools announcement when I found that. This is definately real.

Someone should poll this!! To me I don't think it is real. If not, he picked a bad time to reveal it.

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

I don't understand that part of the article... Look at this:
but if Rybka is displaying +5.12 or more the outcome is 99.99999999% secure. That is approximately the confidence number we give to our King's Gambit results: 99.99999999%.
If the probability of a 5.12 score being a win is 99.99999999%, shouldn't the full calculation (which surely involves a huge amount of >=5.12 scores) have a much smaller probabilty of being correct? And yet he claims the same probability?
