In some games the stock remains untouched throughout play of the hand; it is simply a pile of "extra" cards that will never be played and whose values are unknown, which will reduce the effectiveness of "counting cards" (a common strategy of keeping track of the cards that have been played or are yet to be played). In games without bidding, trumps may be decided by exposing a card in the stock as in Triomphe. In other games, the winner of an auction-bidding process (the taker or declarer) may get to exchange cards from his hand with the stock, either by integrating the stock into his hand and then discarding equal cards as in Skat, Rook and French tarot, or in a "blind" fashion by discarding and drawing as in Ombre. The stock, either in its original or discarded form, may additionally form part of one or more players' "scoring piles" of tricks taken; it may be kept by the declarer, may be won by the player of the first trick, or may go to an opposing player or partnership.
