In the sport of curling, the skip (also called a "skipper") is the captain of a team. The skip determines strategy, and holds the broom in the house (target area) to indicate where a teammate at the other end of the curling sheet (playing area) should aim the stone. The skip usually throws the last two stones in the fourth position, but may play in any other position.
Overall, the skip leads the team and provides strategic direction. The skip calls shots teammates to play, through verbal direction and physical gestures. In many cases, skips communicate the planned trajectory of the shot by tapping their broom on the ice, and motion to other stones in the playing area if those are involved in the planned shot. The skip usually determines the required weight, turn, and line of the stone, and holds the broom for the throwing player to aim at.
As each stone is delivered, the skip calls the line of the shot and communicates with the sweepers as the stone travels down the sheet. The skip gauges the stone's path and calls to the sweepers to sweep to maintain the stone's path. In most cases, the skip, playing the fourth stones, must be able to deliver these last stones comfortably—a difficult task in that the last stones are usually the most crucial to the end. As the person throwing last stones, the skip must also have a good repertoire of shots and the ability to execute many types of shots at will.
As the game progresses, the skip must assess different aspects of the game, such as timing of the rocks and characteristics of the curling sheet—and use these to choose the most optimal shots and tactics. The skip should be able to read the ice and call the game accordingly, taking into consideration the ice conditions. Moreover, the skip must understand the playing style and strengths of each player on his or her team. As captain of the team, the skip uses knowledge of the teammates to call shots according to their abilities and orients the team's strategy towards its strengths. The skip must also observe the opposition's gameplay and pinpoint their strengths and weakness to shape the team's strategy to put the opposition at the least advantage.
