Don’t ask “Who’s more powerful?” Trying to estimate whether you or your counterparts are more “powerful” is risky. If you conclude that you are more powerful, you may relax and not prepare as well as you should. On the other hand, if you conclude that you are weaker than the other side, there is a risk that you will be discouraged and again not devote sufficient attention to how you might persuade them. Whatever you conclude will not help you figure out how best to proceed.
