One big difference between computers and humans is that we have read aron Nimzowitsch's "my system." Most of us know the famous quote: "The passed pawn is a criminal, who should be kept under lock and key. Mild measures, such as police surveillance, are not sufficient." So I might know to blockade a passed pawn, even if i can't caclulate exactly how the passed pawn will make it to the 8th rank. I always assumed that engines recognize the value of a blockade, but i think maybe rybka is demonstrating that they underestimate the value?
