angelcamina (you have seen his games on this blog before) likes to play the Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+) at bullet speed - one minute per game, no increment.
His opponents sometimes just lose to the strength of the attack. Other times, they work to "solve" the Jerome, but this takes time off their clock, so they slip and drop material and lose. Or, they simply run out of time.
Here is a recent game, with a couple in the notes, to see how it's done.

Black has done very well, but it does not matter, as here White won on time. Bullet chess can be cruel.
