Hi at all

Here is my first post in the very good chess programming forum

I am french (excuse my english OK!) . I (try) to develop a chess program ; his name is JARS , version 1.88 in C langage . I'm so beginner in programmation .
I think JARS play chess about 1100 - 1200 elo .... whith alpha beta and a lot of quiescence (bof!)
I read the great program TSCP (thank you Tom!) and I try to play whith JARS under winboard (I wrote as the model of TSCP)
Jars don't boot under winboard ... ffff!
I'm happy If someone can help me , I can send my source
Thanks and congratulations for yours engines !

thanks for your kindness Dan
I give the winboard.debug file
gnuchess vs jars
I don't understand the lines "coup illegal!"
The message is in my engine (of course!) but not appear when jars run on console (so well whith somes bugs in 3reps rule ...

)

Do you use the word 'coup' for 'move'?
Winboard commands must be made in exactly the way described in this document:
http://www.tim-mann.org/xboard/engine-intf.html

Without seeing the source of your program, I think it will be hard for anyone to help.

Why not post the source to your Winboard command parser?

by **daniel anulliero** » 24 Feb 2007, 01:06

hello dan
so ... coup is used for printf (see winboard() )
I tried to write this fonction on the model of TSCP , but it's dificult to understand for me (I'm a beginner in C langage) . I saw the winboard protocol but ... in english only it's hard for me ...
At last , here is the winboard function:

Code: Select all: void xboard() { char line[256], command[256]; int i; int m; int post = 0; COUP meilleur_coup; signal(SIGINT, SIG_IGN); printf("\n"); init_debut(); couleur_JARS = VIDE; for (;;) { fflush(stdout); if (side == couleur_JARS) { meilleur_coup = JARS_joue(prof_max,0,post); printf("coup %s\n",move_str(meilleur_coup)); jouer_coup(meilleur_coup); affiche_resultat(); continue; } if (!fgets(line, 256, stdin)) return; if (line[0] == '\n') continue; sscanf(line, "%s", command); if (!strcmp(command, "xboard")) continue; if (!strcmp(command, "new")) { init_debut(); couleur_JARS = NOIR; continue; } if (!strcmp(command, "quit")) return; if (!strcmp(command, "force")) { couleur_JARS = VIDE; continue; } if (!strcmp(command, "white")) { side = BLANC; couleur_JARS = NOIR; continue; } if (!strcmp(command, "black")) { side = NOIR; couleur_JARS = BLANC; continue; } if (!strcmp(command, "st")) { sscanf(line, "st %d", &temps_max); temps_max *= 1000; prof_max = 30; continue; } if (!strcmp(command, "sd")) { sscanf(line, "sd %d", &prof_max); temps_max = 1 << 25; continue; } if (!strcmp(command, "time")) { sscanf(line, "time %d", &temps_max); temps_max *= 10; temps_max /= 30; prof_max = 30; continue; } if (!strcmp(command, "otim")) { continue; } if (!strcmp(command, "go")) { couleur_JARS = side; continue; } if (!strcmp(command, "undo")) { if(!nb_coups) continue; couleur_JARS = VIDE; dejouer_coup(); affiche_echiquier(); continue; } if (!strcmp(command, "remove")) { continue; } if (!strcmp(command, "post")) { post = 2; continue; } if (!strcmp(command, "nopost")) { post = 0; continue; } /*l'adversaire a entre un coup?*/ m = verif_coup(line); prof = 0; if(m == -1) printf("coup illegal\n"); else if(jouer_coup(liste_coups_peres[m])) { printf("coup illegal\n"); dejouer_coup(); } affiche_resultat(); } }

Bonjour Daniel

Bien sûr qu'il y a des Français dans la salle

Bienvenue au club, et bonne chance à ton module ! Dès qu'il sera prêt je peux l'intégrer à mes tournois si tu veux.

Olivier

salut olivier

merci pour ta réponse (et c'est quand même plus facile à écrire en français! :wink:

)
Je suis souvent allé voir les tournois sur ton site , ainsi que celui de leo (avec le désir d'en faire partie bien sur!!)
Et c'est volontiers que je t'enverrais mon prog , lorsque mon soucis avec winboard sera réglé!
Je ne vois vraiment pas ce qui cloche dans winboard() ... pfff! migraine!
enfin merci encore Olivier
and thanks again Dan

Hi Daniel,

I think your winboard code misses handling of at least the following commands which are actually sent by WinBoard to your engine:

- protover
- random
- level
- hard
- computer

For a first, very simple approach you might ignore all of them, perhaps except "level" (but follow the link provided by Dann for more details). Just "continue" when detecting any of these commands. Also there may be a few more commands to handle.

By not handling them you fall into the piece of code where you expect a move sent by the opponent:

Code: Select all: m = verif_coup(line); if(m == -1) printf("coup illegal\n");

which would explain your problems.

Btw in console mode your engine does not receive these commands (no WinBoard GUI at the other end) but you may reproduce the behaviour by simply typing the commands "protover 2" or "random" at your move prompt. You should see "coup illegal" in both cases.

Finally you have to change "coup" into "move" when sending the engine's best move (meilleur_coup) with 'printf("coup %s\n", ...)'. The WinBoard protocol expects the word "move" here.

The same applies to 'printf("coup illegal\n")', better use 'printf("Illegal move: %s\n", line);' to match the protocol requirements. This would also help you to identify the command or move your engine claims to be illegal.

great thanks for your reponse , sven

I will change all that

good page for your "surprise" . I will test my "jars" against your program but ... not immediately !... :wink:

bye !

by **daniel anulliero** » 24 Feb 2007, 22:41

Thanks again sven!

I changed all of them and now , JARS works in winboard mode

But little buggy ... I work for new problems now ... :wink:
