The Pelican Caller is a Better Caller, who commits himself at the game announcement

For a Pelican Caller, it is more important to take the third to the last trick with the Pagat than to win the game. This means that no other player should have Tarock at the time of the third to the last trick. Therefore, the declarer and his partner must do their best to reduce the tarocks of the opponents.The easiest way to do this is playing tarocks in this way: One partner leads a lower tarock and the other partner overtrumps high. The partner of the declarer should play tarock whenever possible as long as the announced goal seems to be achievable.

For a Pelican Caller you must have Tarock-III in your hand. Additionally, you should have at least 8 rather good tarocks.

Having kings of a short color suit could be helpful to win a trick of that color without losing tarock.
