It’s been four years since a top grandmaster dared cross pawns with a strong computer — and it’s not likely to happen again.

Garry Kasparov, who should know, declared the era of Man vs. Machine matches “a thing of the past.”

The former world champion, who famously lost to Deep Blue in 1997, played two more matches against computers, drawing with Deep Junior and X3D Fritz in 2003.

“With my knowledge of computers, I know I will always be able to win a game — and, I believe, a match,” he said after the Junior match, which was supposed to be an annual event.

But Kasparov, who recently bought an Upper West Side penthouse, wrote in the New York Review of Books that the supremacy of computers is “now apparent.”

Actually it’s been apparent for some time.

His Russian rival Vladimir Kramnik was crushed 4-2 by Deep Fritz in 2006 and Michael Adams of Britain only managed one draw in six games with Hydra in 2005.

Since then there’s been little sponsorship interest in what would certainly be another lopsided embarrassment for humanity.
