Re: test position
Critter must have something wrong; crafty 23.4 (1 thread) says mate in 8.
Fruit 2.1 can't find the mate, it thinks that the position is a repetition draw:
HIARCS v13.2 also thinks it is a draw:
Stockfish 2.1.1 says position is a draw:
So 3 draws, 1 mate; Dr Hyatt can now proudly say that his program is better than the World Chess Software Champion.

Matthew in your mate in 8 line, it calls for 6.Bxf3 as next move in this position which is incorrect. please check why.
Note the e4 pawn preventing the Bishop from capturing the Rook after this line. Tell Doc Hyatt he must return the prize money for the Mate in 8.

Re: test position
My guess is that he set up the position manually (rather than by entering the FEN) and omitted the e4 pawn.kgburcham wrote:Critter must have something wrong; crafty 23.4 (1 thread) says mate in 8.

This is actually a mate in 16, and a fun one at that.

Re: test position
Hello to everybody:
[d]rk3bnq/1P2p3/1B1pPp2/2N2Pp1/2BPp1Pp/2r3P1/P7/1K6 w - - 0 1
I analysed this position with Deep Rybka 4.1 w32 and Komodo 3 w32 under Arena 2.0.1 using 128 MB of hash. My system is an Intel Pentium D930 (2 cores) and 2999 MHz (without overclocking):
Deep Rybka 4.1 was fairly fast (less than 30 seconds in my 'old' system) but depth 2 (with 197 nodes searched) is really interesting; then going with Komodo 3, this wrong mainline was exactly reproduced and the engine stopped analysing. It is very curious, since Komodo 2.03 JA w32 is stacked with -0.05 evals, giving a repetition line (Bd5+, Rb3+; Kc1, Rc3+; Kb1). So, it looks like a bug introduced between 2.03 and 3 versions of Komodo.
Regards from Spain.
Ajedrecista.

Re: test position
This #16 is already in the ChestUCI database as mirrored position.
So if you let ChestUCI analyze this position in one of the 'special' modes (Special or AutoTurbo) it will find it in the database and automatically use the stored special parameters (which are of course also valid for the mirrored position):

Re: test position
Hi Franz:

In fact, the first engine I tried was Chest UCI 5.2 with 128 MB of hash in AutoTurbo SearchMode if I am not wrong: the position was solved in around 0.84 seconds... then I realized that it was in the database indeed. I cleared hash, set hash table to 64 MB and time to solve this problem was 828 ms (a little less than with 128 MB of hash). Simply no words for this excellent mate solver! Just a pity that Chest will not become multithreaded... the same story as Cake 1.85 (and former versions of Cake), an excellent freeware checkers programme by Martin Fierz from Switzerland (only single core and w32, as Chest UCI). Anyway, I must say that Chest is excellent once again. Thanks!F.Huber wrote:This #16 is already in the ChestUCI database as mirrored position.
