Engines vs Champions

today engines have become very strong . i wonder whether todays top engines like rybka, Houdini, etc can be beated by world champions or grandmasters.

thanks

Since 1997 computers had been better at chess than human.

It doesn't matter, though, because people only care about being better than other people.  The world's best sprinter doesn't care that a cheetah is faster, or a motorcycle.  The world's strongest man will never lift as much as a crane, etc.

Here's an interesting video of Nakamura beating Rybka in blitz playing an anti-computer style.

Ukrainian sensationally beats world's smartest chess programme

no really, we can call that luck, you can't compare a chess engine with a human no anymore that times gone, now chess engine can teach gm and train gm  i am sorry , but that is the ugly true my friends, if nakamura beated rybka 1 time it doesn't mean  nothing when i see him beating that engine alot of time i would be agreed, and every engine have different style of playing , i would like see nakamura playing against houdini and i am sure what is the = houdini won   bye :)

1997 is a milestone, but I would say in 1997 it was the first time that a computer defeated the human WC in matchplay. Computers still suffered defeat afterwards.

Not sure since when computers started dominating with no real contest.
