computers in both sides.

I composed a position when I can beat rybka by both sides and not because of a bug that is only rybka's bug.

The question is if you can find a position from games when I can beat rybka with both sides.
getting a position when I can get 1.5/2 against computers is probably no problem because you can find a position from human games when rybka does not understand some simple fortress.

The question is if you can find a position from practical game that I can get 2/2 against rybka with no special preperation.

I would suggest hunting for some slightly off-beat Dragon positions with opposite castling. For example, black plays an early a7-a6. Now, maybe Rybka won't find the best way to attack black on the kingside, and you may be able to win as black. And you may be able to win as white as well, figuring out how to get in the attack first.

It depends on how strong a player you are.

yes, there exists some positions where I would Destroy the computer. There are some Sicilian Scheveningen lead white up a pawn in endgame an no computer can finish the game.  As Dagh has pointed out, computer cannot recognize the drawish nature of some the lines and will miss the small oppportunities for increasing chances in such positions.  Dagh is quite the chess genius. The damn redlines in the .ctg books screwed a lot of people up.  The answer to the original question is of course, 'yes', and I will post at least one example tomorrow.

Note that I did not ask for 1.5:0.5 result but for 2:0 result a(so if computer cannot win endgames with pawn up it is not going to be enough because the computer needs to lose and only drawing with pawn up is not enough) and I also did not ask for a position when you use the fact that you remember some theory moves that the computer does not know.

I think that I will try the position that you are going to post to see if I can beat the computer 2-0
Note that I am not an expert in the Sicilian Scheveningen and in OTB games I do not play 1.e4 c5 with black.

This is actually a very simple problem in 2.3.1. Just pick a position with the winning side about to commit suicide because of the promotion bug. :-)

See my first post

I do not mean to position when I can beat rybka because of that bug.

Sorry I didn't carefully read your original post.  2:0 result not because of glitch. I understand now.  There must be some position but the problem is I can't seem to come up with one!

How about some position where the side to move immediately must find a really deep winning sacrifice, or otherwise he's losing.

This doesn't necessarily need "special preparation", since as a human you could play the sacrifice by elimination of the alternatives, which is one area where Rybka is lacking.

Exactly Vasik!

I think some positions like these (not necessarily with a sacrifice involved) can be found in some really good endgame studies. Try the book 2545 Endgame studies. Some of them (trust me) will do!!!! Endgame studies can easily appear in serious games!
