~RRChess~ by Robert Rayment. Program to solve checkmate problems and play chess games with another person or against the computer. The chess engine is not very strong, only operating at 4 or 5-ply, so you should be able to win fairly easily but it might surprise you at times. Making such a program bug-free I found quite difficult. So far as I can tell, all the legal moves, castling rules, en passant, promotion etc are OK. There are WAV sounds in the resource file for CHECK, CHECKMATE etc. Games and positions can be saved and loaded. See Help for more info. in particular the section on Starting a game. (Zip 500 KB).
__________________________________________________
Update: to allow computer to play on, if is it's turn, when move list is double-clicked. Code cleaned up a bit from CodeFixer.
__________________________________________________
Update2: added a couple of extra color schemes. These can be changed in Sub cmdColorSchemes.
__________________________________________________
Update3: fixed bug on sound skipping.
__________________________________________________
Update4: correction to playback when computer given odds - so many subtleties!
__________________________________________________
Update5: some typos and menu re-arrangement.

It's the first chess game that I see in PSC, it's VERY LIMITED but it's an excellent beginning, sure in future it can be better.

Ah, a suggestion the machine thinks too much a play, don't give so much priority to the first 3 plays, it's almost impossible to make a jacke in a single 3 plays.

Heriberto: It does play a couple of Book moves at the beginning of a full game - see the Help.

Heriberto: Also there are other chess programs on PSC, in particular see Ulli's at CodeId=31064.

Thanks Robert, I play with this, it's really excellent to be a beginning.
Although it lacks to improve the machine of inference of the computer a little.
Anyway thannks for sharing and take my 5 fives.

How do I make an roque?
(If this comment was disrespectful, please report it.)
|
11/14/2005 10:50:32 AM: Robert Rayment
Heriberto: 'roque' is that a 'rook' and if you mean promotion then for a human player a selection box comes up, for the computer it can only promote to a queen.

Robert, a great submission! This is something I've never tried myself and its good to see something so original. 5*

The meaning of Roque (sorry this word I write in spanish coz I didn't find as translating it) is: When the King (only first one) move to the Position of the Tower I produced a "Roque".
This play one can only make if the king has not moved of his beginning and the player makes it an only time in the game.

Heribert: What English call 'castling'. Simply move the King 2 squares when castling is allowed. Sorry your English is confusing but much better than my Spanish :)

Thanks for the information, now I can see castling, yeah my english is really bad.

Kurt Programmer you should be the dad of the chickens of the programming to only give a point.

Heriberto: 'dad of chickens of the programming' I love it :) Kurt programmer, planetsource, samppa - probably the same person. There's always been 'one-voters' on PSC - just their bit of fun. As a comment on submissions it's meaningless - no worries.

I like it. Instantly noticed a rules problem though; it doesn't appear to recognise the En Passant (sp?) capture move?
On the whole though, fantastic work!
(If this comment was disrespectful, please report it.)

12/17/2005 2:01:03 AM: Robert Rayment
I'm surprised, it passed all the en passant tests I tried! Are you sure you are applying the correct rule?
(If this comment was disrespectful, please report it.)
|
12/17/2005 3:34:33 AM: RedGalaxy UK
Positive. My first move was a pawn two rows forward, the computer's move was the exact opposite pawn also two rows forward. That should allow me to take the computer's pawn by moving mine to either side of the computer's. Tried this and it didn't register it :(
(If this comment was disrespectful, please report it.)
|
12/17/2005 8:53:48 AM: Robert Rayment
I'm afraid you've got the rule wrong! For white to take en passant it must have a pawn on row 5 (not 4). Then black also has to move to row 5 but on an adjacent column, white can then take as if black had moved to row 6. Vice versa for black where black has to be at row 4 etc.
(If this comment was disrespectful, please report it.)

12/18/2005 8:56:45 AM: RedGalaxy UK
Oops! Shows how long it was since I played a full game... I had the right rule, just wrong positioning. Now I'm going to hide for my mistakes!

Good work again. If I may offer a suggestion, would there be a marked improvement if some of the engine routines were written in asm, or by using bitboards, etc ? It would also be nice to see different implementations of the search, like heuristics and pruning, alpha-beta versions, etc.
(If this comment was disrespectful, please report it.)
|
12/30/2005 9:37:01 AM: Robert Rayment
Jose: It does use alpha-beta pruning apart from finding checkmates which require brute-force. There are lots of ways to improve the speed, some of which I mention in the Help. I notice on the Web that some chess programs have been years in development - not sure I want to:) Thanks for comments.

I've played quite a few games on the
