Subject: How do you determine if your opponent is a computer?

Hi. I posted this questions 7 days ago but seemed to be ignored for some
reason. I hope it's ok to repost it. Anyway, I hope someone will finally
notice this one.
I am just curious if you have a way of knowing whether your opponent in
an online chess game, such as that in excite or msn, is really a human
or a chess engine. How would I know if the one moving the pieces at the
other end of the board is some souped up cousin of sanny's getclub?

If he wins all the games everytime and makes no blunders. Humans how
good he is will make atleast 1 blunder in 10-20 games. But Computer
will never make a blunder as it do not get tired thinking a lot.

GetClub is now much improved So you will not be able to win against it

That's a bunch of crap.
Computers blunder all the time.
The one thing they wont do is make a tactical blunder within their search
depth. (With modern hardware, there should be no tactical blunders within
12-15 plies, even on moderate hardware at faster time controls.)
But they still make positional blunders.
They still make tactical blunders whose consequences are beyond their search
depth (or that are caused by over agressive pruning methods.)
They still have problems with the horizon effect. (Delaying moves, etc.)
They still make moves that humans think are blunders because they haven't
analyzed the results as completely and the move they think is so good
actually isn't.
They can still get into time control problems.
The top programs don't blunder as much as the weaker programs, of course.
And today's hardware mean that the average quality of play has improved.
But computers still blunder.
