9-move checkmate problem driving me bananas

Post by Chessnut1071 »

FEN[211] = "6rk/1p1R3p/2n3p1/p7/8/P3Q3/1qP2PPP/4R1K1 w - - 0 1"; // Parekh Abhishek 9-move mate

Although my engine finds the mate it takes way too much time and I have to clear out the history and Zobirst hash every iteration of white's first move. Some engines claim they can solve this problem in seconds. Okay, it's not a fast engine, even my slow engine can do 250,000 legal calls per second. What search function are they using. Apparently, my function fails miserably:

this is all I can fit into 12 bits:
1) history by ply
2) check
3) squares close to enemy king
4) number of enemy king moves
5) capture pieces

appreciate any help, this one is driving me bananas.

Chest say that 1.c3 mates in 8 moves so this is mate in 8 and not mate in 9.

Stockfish saw the mate in 8 faster but I was not sure if stockfish is right so I tested with chest.

Good old Fruit 2.1 takes 0.87 sec on 3.2GHz i7 to find mate in 9. After 7:11 minutes it corrects that to mate in 8:

You can always count on The King here. It finds Mate in 9 in about 0.1s, then announces Mate in 8 in 11s.

I see said the blind man as he picked up his hammer and saw; however, I don't see the function used to achieve that great time. I'm willing to give 3 blessings on his goat herd if he is willing to share that function with this poor, old, run down programmer who can't afford his electric bill.

Well, Fruit 2.1 is open source, so it would be easy to have a look. There is no magic there. It is just alpha-beta with a quiescence search of good and equal captures. Using null-move pruning, check extension and simple late-move reductions (of 1-ply only). And move sorting by MVV/LVA and SEE for the captures, and killer plus history for the non-captures. Evaluation is PST, material table, mobility, Pawn structure and King Safety.
