Bullet chess - completing a game in a minute or less - requires a sharp opening - and patience, interestingly enough.
In the following game, Black avoids being blown off of the board in the first few moves of the Jerome Gambit, happily holding onto the advantage that can come from a solid defense.
White, in turn, plays along patiently, convinced that he will get his chance to tactically get the advantage. He does, and he wins a miniature.

As long as he defends solidly, Black will keep his advantage of a piece for a pawn, even with an uneasy King.
