With sudden force.

In music, a sforzando (sfort-SAHN-doh) indicates an abrupt increase in volume. The performance mark—shown on the center of the card—is usually placed over a single pitch or chord, which is played at a sudden increase in volume. The effect is startling. 

Sforzando is a Directive card, directing the querent to act quickly and with force. It can also indicate a shock, a sudden arrival of the unexpected.
