Research direction

Start at chess/ChessBoard.java:108, where the ClassCastException occurs, then trace the move through common/Board.java and common/TreeNode.java. Run common.GameAIMain to reproduce the failure and inspect how pieceFromTo handles the moving piece. Done means the AI simulation completes without this cast failure and the king remains trackable.
