==Honor rules==

Trick-taking games normally have several rules regarding which cards may and may not be played to a trick. For example, most games require a player to follow suit – that is, to play in the suit led – if possible. Rules of this sort are sometimes called '''honor rules''', because there is no way to detect a violation at the moment of its commission, although it will almost certainly be discovered later. For example, if a player does not play a spade to a trick where spades were led, other players will simply assume that player has no spades and note the fact in future play decisions. However, attentive players will soon notice the violation when a spade is played to a subsequent trick. 

Some honor rules in different trick-taking games include the following:

*[[Pinochle]] requires players to
** play to the led suit unless void in it, with a potentially winning (higher than the highest-so-far) card, if possible;
** if void in the led suit, trump with a potentially winning card, if one is in their hand; or
** play some remaining card.
*[[Bourré]] requires players to
** play to the led suit unless void in it, with a potentially winning (higher than the highest-so-far) card if possible;
** if void in the led suit, trump with a potentially winning card;
** play to bourré as many other players as possible.
*[[Forty-fives]] requires players to follow suit or play a trump card if possible (note that the Ace of Hearts is always a trump card and must be played on a trump if the player holds no other trumps). Some variants permit reneging with the 5 of trumps.
