Insanely buggy move generator, please help

Indeed. When you can do ALL of these correctly, then you can pretty safely say that your movegen is accurate:

8/3K4/2p5/p2b2r1/5k2/8/8/1q6 b - - 1 67 // perft(7) = 493,407,547

I think there is a typo here. Should be 493,407,574

I agree, my engine says:

Test Complete : 493407574 nodes visited

My perft concurs, 574 not 547:

Code: Select all

louis@LZsT5610:~/Documents/Chess/Kirby$ ./perft_pa
FEN string = 8/3K4/2p5/p2b2r1/5k2/8/8/1q6 b - -
Depth = 7
Leaf nodes = 493407574
Time taken = 9114 ms

Yep, typo. Combined with a bit of dyslexia it's amazing my engine works at all!

Thanks

Would you mind if I'd reply you here?

Well, it seems I do exist ... Don't reply to my PM here, please. Maybe the admin Sam Hull can help you to find out why replying to my PM does not work for you.

Have not heard from you much regarding your engine lately. How are things going? Have you tested your move generator and squashed the bugs?

Haven't heard much from him either. He was interested in working with me, so I sent him what little code I had, and asked him to write a FEN parser for it, because the ones I had written were buggy, and didn't work. That was 10 days ago. Haven't seen any progress from him since then.

Maybe he's studying LALR(1) grammar's.
