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

For a Pelican Caller, it is more important to take the fourth 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 fourth 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.

The Quapil Caller is an extremely risky game. Even if you have a sequence of tarocks largely closed from the top down, it is possible that another player has so many tarocks that the Quapil can never make the 4th final trick. Instead, consider playing a Tree if you have many good tarocks but no smaller Better Piece.

For a Quapil Caller you must have Tarock-IV/IIII in your hand. Additionally, you should have at least 10 very good tarocks.

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