This will make SharpChess compatible with Mono (so it becomes cross-platform).

In project SharpChess in file frmMain.cs line 2946 (in method frmMain_Load) there is a line where you combine absolute path to Documents folder with save file name ('BackupGame.sharpchess'). The line looks like this:

Game.BackupGamePath =
Environment.GetFolderPath(Environment.SpecialFolder.MyDocuments) + @"\BackupGame.sharpchess";

Build from sources is OK.

But when running in Ubuntu Linux with Mono 2.10.6 this line produces completely wrong path due to backslash symbol '' and app crashes with unhandled exception.

I suggest you to replace this line with

Game.BackupGamePath = System.IO.Path.Combine( Environment.GetFolderPath(Environment.SpecialFolder.MyDocuments), "BackupGame.sharpchess");

Then SharpChess works well in Ubuntu Linux also.

This function adds a lot of power and energy and memory saving to the engine, stockfish and hiarcs also has it, however I think they can be improved, I am working on it currently but debugging eats my time...

Currently after getting stalemate by repetition (and result 1/2-1/2) it is possible to press 'Think' button. Then computer player will make next move and the game continues.

I feel this is very wrong behaviour: the game should fully stop after getting in final states such as checkmate and stalemate.

Currently I observe very strange issue: computer player will never move until I press Ctrl-T (item 'Think' from main menu).

It looks like this behaviour is by design, but it is too boring to press neccessary button every computer's ply.

Hi,

I am about to embark on an attempt to implement a chess engine written in c#. Researching if there are existing reusable WinBoard protocol implementations I came across the SharpChess codebase here on GitHub.

As I peeked into the code I found an apparent copy – paste bug around line 308 of Brain.cs.

The code reads:

            if (this.MyPlayer.CanClaimInsufficientMaterialDraw)
            {
                WinBoard.SendDrawByFiftyMoveRule();
                return;
            }

But should read:

            if (this.MyPlayer.CanClaimInsufficientMaterialDraw)
            {
                WinBoard.SendDrawByInsufficientMaterial();
                return;
            }

I can’t be arsed to fork the code and create a pull request, so I'm posting like this instead.

This is no showstopper as the draw will be claimed regardless. But the reason fo the claim might look strange to a human reader.

Regards!

SharpChess requires an installer.
