Your job as a Prime Minister is to set the grounds for this debate. State the motion that you were given and provide a logical link (i.e. via a definition) to your proposition (i.e. whatever it is your case is proposing). That would be a seamless task if it weren't for the opposition, those evil people on the opposite side of the house who are already planning on challenging your definition. Being that you've already studied and know the rules pretty well, you don't want to give them the satisfaction of providing any of the prohibited types of definitions. That being said, your team also has another vital role to fulfil, "the burden of proof". You need to prove your case and why it should stand before this house. Though this role will also be dealt with by your partner, you should spend some time providing reasons to back up your case.

When defining the motion, you're in a very strategic position. The entire debate will (hopefully) follow up on what you are about to say. You might just as well take advantage of that position to give an edge, a competitive advantage to your side of the house. This should be done carefully and with extreme caution, so that the opposition doesn't see through your plans. One way of going about, is stretching the motion, to something more inclined to the government side. As long as it's not absurdly removed from the originally intended discussion, and leaves room for the other side to debate, no reasonable person would ever reject your definition. You need to make yourself sure you cover thoroughly all aspects of your definition. Murphy's law applies here; "If there is some chance that a detail arising out of your definition will destroy your case, then it will definitely come up". Opposition speakers are more often than not involved in nit picking your case for holes, don't let them find any!

Ok, so you've got yourself a definition, what's next? Well, if there is a very weak argument the opposition could make against you, then make sure they think about it. That can be done by addressing it briefly, or by mentioning something that hints in that direction. Luckily, they'll fall for the trap, and their opposition will take that track. They will use a weak argument to oppose you and your partner will have an advantage when responding to them.

Being a good opening team is probably one of the hardest roles in debating. Statistically, teams in your position tend to get scores nearing both extremes of the spectrum. Keep these guidelines in mind, practice them often and you'll sure be way ahead of the other team's thinking.
