The picker must keep at least one card of the fail suit in his hand (i.e. cannot throw them all off) until the first trick for which that suit is led, and then of course must follow suit. Also on the first trick for which that suit is led, the partner must play the ace (even if the player has another card of that suit). If the picker has all 3 fail aces, he may call a 10 instead of an ace. The picker is obligated to hold the ace of that suit in his hand. When the called suit is led, the picker must play the ace.

The normal rule is that if the picker has the jack of diamonds, whether as a result of the deal or picking up the jack in the blind, the picker must play alone. However, there are a number of variants within this method of play. Sometimes, the picker is allowed to "call up" to the
