Legal proceedings – or legal disputes per se – are like chess. The only difference is that you don’t always start with the same starting position.
While in chess each player starts with 16 pieces in the same position, in legal disputes the starting positions are different in each case and usually dictated by circumstances. Like when one is supposed to continue a chess game started by another in a certain position.
Conducting a trial in which you have the law and evidence clearly on your side is like playing a chess game in which you have the queen and two more rooks than your opponent. That should be easy to win.
The real professional, however, will still get a draw or an acceptable settlement – by legal means – even if the opponent has the far superior position.
