Don’t let your opponent sense that you’re digging into your position without being willing to consider alternatives.
When your opponent states what they believe to be a fact, probe deeper into the fact with questions that expose its flaws.
there will be times when your opponent gets the better of you, and they corner you. When this happens, just concede the win, and you should always be graceful in defeat. Nothing is worse than a person who argues for the sake and refuses to give in.
