Welcome to the forum, Mark, and good luck with your chess program. It took me 22 moves to win!

Code: Select all

1. e4 Nf6 2. e5 Ne4 3. d4 Nc6 4. f3 Nxd4 5. Qxd4 d5 6. fxe4 e6 7. exd5 Qxd5 8. Nf3 Qa5+ 9. Bd2 Bc5 10. Bxa5 Bxd4 11. Nxd4 c5 12. Bb5+ Kf8 13. Nf3 f6 14. O-O a6 15. Be2 Bd7 16. exf6 Bc6 17. fxg7+ Kxg7 18. Bc3+ e5 19. Nxe5 Be4 20. Bh5 Rhd8 21. Ng4+ Kg8 22. Nh6# 1-0 

Still, it didn't play any illegal moves, and it didn't try to break the board over my head

@James
I broke your 22 moves record : 15 moves! (Played with no book)

Code: Select all

1.e4,Nf6; 2.e5,Ne4; 3.Bc4,Nc6; 4.d4,e6; 5.c3,Be7; 6.Qg4,Na5; 7.Bd3,Ng5; 8.h4,h5; 9.Qg3,Nh7; 10. Qxg7,Rf8; 11.Bxh7,Bxh4; 12.g3,Bg5; 13.Bxg5,f6; 14.Bg6+,Rf7; 15.Qxf7 1-0

@Mark
Is your engine using non-minimax strategy? (I ask because 12. ...,Bg5 is a one-ply blunder).

I didn't play, but Schola did (your engine had white):

A couple of comments. As has been previously mentioned, there are some major blunders which points to an "unusual" search strategy.

The XBoard protocol is pretty easy to implement (I would strongly recommend protocol version 2 but version 1 should be very easy to add to your engine). This would allow it to play against other engines and I think you would find that is a great way to figure out weaknesses.

Also, for the current interface you have it would be a great improvement to output the move it made underneath the boards - though it was actually good visualization practice for me to have to hunt for the move on the board!

Good luck!

Andy.

Thanks James, a good result then

[mainsworthy]

Hi Andy great idea winboard, i will look into it!

[mainsworthy]

Im thrilled to have got your results! and found this forum thankyou!

Welcome to the forum and to the begining of a new lifetime hobby. If you are like most of the rest of us you will be working on your program for years to come.
Let us know when you get it to work Winbord or Xboard so we can put it in some real tournements.
Good luck
Bill

If you would only implement a minimal subset of the WinBoard protocol, consiting of understanding the commands 'new' and 'go' plus input moves in long-algebraic notation (e.g. g1f3), completely ignoring all the rest, and output your move as 'move b8c6', it would already be enough to participate in a tournament like Chess War. A new ChessWar Promo-division will start soon there, and you will be able to watch the games of your engine (and the others, of course) life over the internet with the TLCV viewer.

sounds exciteing, Im going to look at it, and give it a go!
