Inhuman Monster Move

[tama]

   Problem http://chesstempo.com/chess-problems/2581 the move is Nb3 atacking a Rook but the computer does not move it because in the long run after u win his queen side pawns he will be forced to give it up for your passed pawns anyways.

   Its difficult to say a  human would leave there Rook hanging in this possition, but it makes sence i just feel like its abit to inhuman.

Hi Tama,

This positions are a little unfortunate, but for now I am much less concerned about them than positions with alternative winning lines.  Whilst white's response looks a bit strange from a Human's perspective, Black's required moves are at least clearly the right ones given white's response.  Ultimately I'd like to avoid this type of response but it is quite a difficult problem as the computer move makes perfect sense from the computer's perspective (although a computer that was more aware of the failings of human players might be able to work out that he could move the Rook and hope the human doesn't find best play).

After I resolve other problems in the generator I'll try and look at automated ways of avoiding this type of response.

Regards,
Richard.

tama:  There is a discussion about the computer making "inhuman" moves in the topic Site Feedback / Better Defense, with 13 posts.  The points are made there that of course it would be nice to have more human-like moves in the defense, but it's very hard to get those without putting them in manually for each problem, which would take years with 17,000 problems.

It's one  of those things in chess, where the prettiest line isn't necessarily the  one that actually shows up  on  the chess  board!

I agree,  that  showing the pawn promotion line for  this problem is more illustrative.

Freaky problem Giving 2 passed pawns and dominate pieces to black would be bad as well.
