Possibilities in chess may be practically infinite, but there's a relatively finite set of common plays. I currently know almost none of them, but hearing the named strategies discussed is as entertaining as the fencing jargon in The Princess Bride. If white opens with e4, for example, black may adopt the Sicilian Defense, prompting white to advance the Smith-Morra Gambit, and so on.
One variation I learned of is called the Dragon, so if there's one thing I'm likely to take away from this, it's to develop the Dragon as often as possible. Using a strategy with a cool name is almost as good as winning, right?
