Critter 1.2 is a new champion ... in mate solving

Post by Jouni »

When Houdini 1.5 come it was by far the best mate solver among playing programs. But not anymore. I tested about 500 longmovers from Chest database and Critter 1.2 solved 15 more than Houdini! Positions were from mate in 10 to 21. Additionally I found these errors in database:

r4rk1/p1q3p1/2p3Q1/4p2p/6bP/2PBP3/PP6/2KR3R w - - bm #12; actually mate in 9
4r1k1/ppp2ppp/2q2n2/2br4/5B2/5Q1N/PP5P/1R3K1R b - - bm #12; actually mate in 10
n5br/1pp3p1/2P1k3/5R1P/4P1N1/B4p1q/3P4/3Kn3 w - - bm #21; actually mate in 17

And this

[d]4Qrk1/3P2pp/p7/1p1q4/3N2b1/6P1/PPP4P/2KR4 w - - bm #14; actually mate in 13

Analysis by Critter 1.2 64-bit:

1.Rf1 Qg5+ 2.Rf4 Qxf4+ 3.gxf4 Bxd7 4.Qxd7 Rf7 5.Qd5 g6 6.Ne6 Ra7 7.Qd8+ Kf7 8.Ng5+ Kg7 9.Qd4+ Kf8 10.Qxa7 Ke8 11.Qf7+ Kd8 12.Ne6+ Kc8 13.Qc7#
+- (#13) Depth: 30/38 00:01:02 297mN, tb=1499

Hi Jouni, a correction: your 2nd position is mate in 9 and the parameters for Chest are
r4rk1/p1q3p1/2p3Q1/4p2p/6bP/2PBP3/PP6/2KR3R w - - bm #9 R-3/K5/P7/X30
4r1k1/ppp2ppp/2q2n2/2br4/5B2/5Q1N/PP5P/1R3K1R b - - bm #9 C2/R-4/K4/P8/X35
n5br/1pp3p1/2P1k3/5R1P/4P1N1/B4p1q/3P4/3Kn3 w - - bm #17 C2/R-4/K4/P8/X35

Addition; these are mate in 10:

8/1p6/1P2k3/2B1N1K1/2pP2p1/1PN1n3/3Pb1pp/8 w - - bm #11;
5N2/4p3/8/4R3/6P1/2P1Rp1p/PKP1nppP/3k1bn1 w - - bm #11;
k4b2/Pnp1p1p1/pB2P1Pp/P2B4/1p6/1P5K/7p/8 w - - bm #11;

So about 2-3 % of database mates are too long?

Hi Louis,
I have put the parameters for Chest. Now, the #10:

8/1p6/1P2k3/2B1N1K1/2pP2p1/1PN1n3/3Pb1pp/8 w - - bm #10; R3/K3/P7/X24
5N2/4p3/8/4R3/6P1/2P1Rp1p/PKP1nppP/3k1bn1 w - - bm #10; C2/K3/P2/X7
k4b2/Pnp1p1p1/pB2P1Pp/P2B4/1p6/1P5K/7p/8 w - - bm #10; K2/P3/X9

These 3 mates have been corrected long ago and the current ChestUCI database already has the parameters for #10 (and it's even 6 months old!).
So you seem to have a very old version.

Thanks for the new wrong mates, I've corrected them and I'll updated the database in the next minutes.

Regards,
Franz

Critter-1.2.1 (8 threads, 4GB hash) solves these easily:
