How does a player win a trick in skat?

In the card game skat, a trick is won by the player who plays the highest-ranking card of the suit that was led, or by the player who plays the highest trump card if any trumps are played during that trick.

Players are required to follow suit if they are able; if they cannot follow the suit led, they may play any card, including a trump card to potentially win the trick. The winner of each trick then earns the right to lead the first card for the subsequent trick.1
