Re: Rybka and Zappa are wrong here

This position is really interesting because most engine cannot see that this is a draw. From the commercila engines I have, only Zappa Mexico II is able to identify in a short time that this is a draw. For the strong free engines I tested, only Bright 0.2c sees that this is a draw. Glaurung 2.0.1 could also see that this is a draw, I stop the analysis when the score was 0.15 (so almost draw).

Notice also that there is a nice bug in Fruit 2.3.1 that sees a mate in 4 moves!!

I used 256 Mb for the hash size and I use 3 and 4 men tablebases

I report only a part of the analysis for each engine in order not to get a too big post

The crazy rook idea need to be improves in chess engines !

Is there engines who evaluate the position as a draw ?

This has been a problem forever, because there are two kinds of repetitions, the kind that you can see to the end, and the kind that you mentally prove that can't be avoided. For this position, all you have to do is to be sure that there is no place the king can go to where another crazy rook check is made by the rook that is currently stalemating the king... Once you mentally figure that out, you are set (as a human). The computer's search doesn't work that way however.

That said, it is solvable as my laptop shows:

Tinker sees a draw here fairly quickly, with and without EGTBs, FWIW
With EGTB (all 5 and some 6):

Code: Select all

 13        0   4.90   3113264  1.  ...   f2f4  2.  e4e3  f4e4  3.  e3d2  e4e2

                               10.  d8a5  a4a5  11.  a6a5
Without EGTB:

Code: Select all

 14        0  11.36   8940269  1.  ...   f2f4  2.  e4e3  f4e4  3.  e3d2  e4e2

                               7.  b3c3  b4b3  8.  c3c4  b3b4  9.  c4c5  b4c4
                               10.  c5d6  c4d4  11.  d6e7  d4d7
Incidentally, Tinker has some special repetition code that considers more than 10 checks in a row a draw. The idea is that after 8 checks the king should be able walk in to avoid a rook check, but just a heuristic and far from perfect.

Re: Rybka and Zappa are wrong here

Post by Ryan Benitez »

I am fairly sure the mate bug in Fruit 2.3.1 in this position is an issue in search focus. If you disable this UCI option I think Fruit will just be as wrong as Rybka and Zappa but not see mate. I have not done a real world test on this yet but playing though this in my head I am fairly sure this the problem. To make Fruit see draw in this position would not be hard but its a matter of how many cpu cycles is it worth to see a rare draw? I would say not many.

Thanks,
Ryan

Hi Ryan,

you are right. I checked it on a different hardware (32Mb hash). The bug still exists with "Focus Search" but without this option there is no bug.

Now WITH "Focus Check" and "Extend Checks" you get an even worse result

Incidentally, Tinker has some special repetition code that considers more than 10 checks in a row a draw. The idea is that after 8 checks the king should be able walk in to avoid a rook check, but just a heuristic and far from perfect.
So, it's not solve accurately.
I bet it's possible to solve it under the real conditions : only the rook can move (if it's took, it's stalemate), extend search for ALL possible positions where the rook make check until position is repeated or rook is took.

Can somebody count all possible positions under these conditions ?
