hai, everyone..im just learn how to use java programing..but i hava a task which is, i hava to create a chess game by using java.So, i wonder how does the Pawn,Casttle,Knight,Bishop,Queen and king movemnt looks like, espeacialy how to implement in java coding?
second, it is have to use an array to create a 2 dimension chess sets?

anyone have any ideas??

ouch... and i thought black jack was hard to do in a few weeks... that was until my program got erased and i had to re-do the whole thing in 3 days... half the code, 2x greater then before lol. As for chess. well that ones hard. your going to have a fun time with that one lol. but good luck with it. your best bet would be to google it and see if anyone has done this before, and if so... learn from them

I have written a chess game some time ago.

This is one way - but it needs some work to be commercially competitive.

Develop a function to analyse a given position in chess and give it a score. The score might be a count of the material (pieces on the board) and some other factors... such as..

- A queen is worth +90, A rook worth +50... A Pawn worth +10, A King worth +infinity etc.
- If two pawns are on the same file = -5
- For each potential move from this position +1.

You can do an exhuastive search through a tree of every potential move, every possible response, etc.. and use what is known as a minimax method. That is search the tree of moves and take the minimum potential maximum scoring value - meaning that the human player will force you into the minimum possible scoring board.

Then - the computer picks the first move in the tree for that position.

You will find that you can search approximately 4 computer/player moves ahead. Any more than this and the tree grows exponentially - it will be too processor intensive to search further forward. The computer will make surprisingly good moves - but you will probably beat it if you try hard.

I am certain that commercial chess games are far more sophisticated than this.

This is all explained in a book - "Computer Gamesmanship" by David Levy.

If you cannot imagine how to do any of this - I could provide you with my source code. If you make any money from it though - I want my cut

Hi,

I have my project to design a computer playing chess program in java. Please let me know if i can get the source code for it?
