I just watched a lecture video from Ben Finegold(St. Louis Chess Club) on You-Tube where he makes a point that when his opponent(a human) is thinking a long time over a move, he invariably makes the wrong move. This is normal time OTB of course, but does having days to ponder over a move give a human an edge? Or is there a point of diminishing return? ie think long think wrong? :)
Humans v Houdini chess engine (Elo 3300)

Oh boy, some people are unable to understand simple things...
Here is the position from my game- it's white's turn to play.
Feed it to Houdini 2.0c or any other engine, and let him think for as long as you please.
After calculating "everything" he will come up with either Ne1 or Kh2, with a close to equal evaluation - but both moves are losing. Factly, Kh2 isn't losing either, as long as white follows the "inferior" plan of keeping the knight passively on g2.
The correct move is either Rc1 or Ra1, which is regarded as way inferior by Houdini, but it draws instead: Black cannot break into white's fortress, despite the fact white having effectively no white squared control at all.
Interesting post. I tried this position on my computer,a fairly powerful one with Houdini 4 pro.
At 30 ply (15 minutes thinking) it prefers Kh2 -0.48, then Ra1 -0.49, and Rc1 -0.61. It means that the engine has improved but it's not quite there yet.
My intention was not to prove IM pfren wrong, which he is not, of course; I just wanted to test my hardware.
It's not so difficult to beat Houdini in correspondence chess. Computers still lack certain elements of positional understanding, and they can certainly be outplayed by a strong player. On rapid/blitz games though, it is a totally different story.
Well... a computer in correspondence chess can spend it's whole time analyzing everything, and thus can find the most major combinations that could arise, and be ready for all of them. So even a really strong player would find himself in trouble against a computer that already knows almost everything that he could play. I think.

You can test your theory in a very easy way.
Play correspondence chess games (in LSS for free or in ICCF if you want to get a Fide Correspondence chess rating) and let Houdini 4 choose all your moves.
Then count how many tournaments you can win.
Here is another case where any engine will fail to play properly. You may let it think for as long as you please- the chances to find the correct play are zero. A strong player can solve it in less than a couple of minutes.
This was recently published at the Chessbase site, but AFAIK no solution published yet. I will not include the solution right now, try solving it without engine aid (or you will never make it).
this is fake white cant draw this game by any moves

You may bet $ 50 to support your claim, sir... preferrably not fake ones.
If you are right, you will win $ 200.
Interested?
if you are right you put the answer but you cant coz is fake , white cant draw i am FM i cant found and I have a GM friend and he says is not a draw so you are a liar or protect your pride if you have

You must be a kid. No self-respecting adult would type out that last paragraph.
if you defend him you are a liar too

It's okay. You used your engine. This is allowed to solve puzzles posted in forums. No need to go for the "I'm a local master and Kramnik is my neighbour" joke
Still, IMs in general know much more about chess than you or me...

I do teach for free, but I make exceptions for arrogant patzers. If you still think white is lost, then place your bet, sir.
Oh, and you are FM of my arse. FM's get a diamond membership for free here. You cannot even lie in a convincing way, it seems.
only you can teach me is how to lie but chess not coz you dont know enough chess to teach me
I'd be surprised as well. I don't believe anyone can outplay Houdini or any top rated engine. Sure, computers have no real positional understanding, but that doesn't mean that a positionally good player will overcome it.
Currently in ICCF word championships the usage of computers is allowed. While there have been a few weak players who have made good results, the vast majority of champions and top rated players are/were also very strong OTB.
This only means that a stronger OTB player can understand and use the information coming out of the engine in a much better way than any ol' n00b with an engine. This doesn't mean that a human can outplay an engine. Not even close.
I think that if the engine is given enough time, it will outplay any human ;-)
i agreed 100% the engine play the best move the human play the most like move to him

Some masters simply want to remain anonymous, dear pfren
But they can remain anonymus, the only ones that will know the master´s identity is the chess.com staff.
What was the result of the two centaur games you played against him?
The score was 0-0. He never challenged me.
Did you try challenging him?

The reality of all this nonsense is that Humans CAN play better than computers, but they will almost indefinitely make a mistake, even in correspondence. Kramnik could very easily obtain a good/great position against the computer, with knowledge of the computer's book etc. and forcing closed positions. (which is still a slight weakness for computers- especially is the compensation offered by pure king attacks like the KID)
I highly doubt he'd convert anything to a win though..it'd be a good match for sure, likely he would blunder or go completely insane. lol

A very fresh example from the ongoing TCEC championship: Houdini is Black against Stockfish.
What did the "perfect" engine play here? Extremely hard to guess...
12...Bc6!!
A sheer touch of genius- right?
Do you think any decent GM/IM would have any trouble demolishing Houdini after that?
Stockfish played as simply as Bd3, followed by castling- and Houdini uncorked the fiendish plan: He transferred the f6 knight to b6!!!
Now Black has an inpregnable queenside fortress: Bishop on c6, knights at a5 and b6. A slight technical problem: all three pieces are doing nothing there, and the poor king is on the other side of the board, stripped of his most valuable defenders...
For the record, the game lasted 26 moves- the Black operator threw in the towel just a few moves before Black getting mated.
I do not mean that computers usually play moves as ridiculous as 12...Bc6. My point is that people do not understand that engines operate on flawed code, and they are pretty vulnerable without proper human intervention. If I had Houdini, or any other engine suggesting such a move during an ICCF/LSS game, I would simply tell him to shut the fook up.
I can't believe you haven't posted in this thread yet: http://www.chess.com/forum/view/chess-openings/1e4-f5--me-and-my-oversized-ego-vs-all-of-you
But of course, should you join us against Irontiger, we may even win.
All these these recorded wins against any engine are Correspondance games when the human is using an engine aswell.
No, Nemeth's are blitz games, and he's not using an engine...
