The international rules of Skat were adopted at the German Skat Congress in Halle in 1998. A card counts as played when it lies fully on the table. Eine (aus)gespielte Karte darf nicht zurückgenommen werden. A card that has been played may not be taken back. Bidding, passing and the announcement of the game cannot be withdrawn either. Chess has the same principle. A player who deliberately touches one of his own pieces must move it, if it can be moved. In German this is the Berührt-geführt-Regel, the touched-moved rule. The card players’ version is the saying Tisch hat sein Recht, the table has its right.
