Puzzle from a Giraffe
Many of the animal chess openings are short games that show one player violating opening principles and getting punished quickly with a tactic. This one from the Giraffe actually comes from a Greco game from the 1600s. The great thing about these games for both beginners is that it shows very clearly why you shouldn't move the queen out too early, or attace before you are developed. Even many club players miss these tactics in actual games.
