All logic for running the game is contained within the OgreApp and ChessApp classes. The application holds pointers to both the Board instance and the Position instance. Each time before the frame is updated "ChessApp::frameRenderingQueued" is called and the game logic is updated.
Each object in Ogre needs to be attached to a separate SceneNode. In addition to that each object that should be rendered must be attached to a separate Entity. The OgreObject base class holds pointers to both the associated SceneNode and Entity (if the object is rendered).
"ChessApp::frameRenderingQueued" calls the "OgreObject::update" method in the board which in turn calls updated on all of its squares which in turn calls updated on the piece that occupies the square. You get the idea.
All position logic is contained within the Position class in order to improve performance.
Commands are global function pointers which use static variables for saving the entered data which in the processed by the application the next time "ChessApp::frameRenderingQueued" is called.
We have quite a lot of debugging capabilities in the engine at this point, we have commands such as bb (bitboard), fen, perft (for which you can also give a 2nd depth parameter to divide the results to the given depth) and pos (sets a predefined position). Type help in the console to see all the commands.

I don't know what Antero and Markus can do but we'll see.

It would be great to keep track of the issues using the Bitbucket issue tracker so that we know where we stand at all times.
