01The left bower trap

Most reneges are accidents with the left bower. Once trump is named, the jack of the same colour belongs to the trump suit, not its printed suit. If hearts are trump and diamonds are led, the jack of diamonds does not follow diamonds: it is a heart. A player who must follow diamonds and has only the jack of diamonds in that colour has no diamonds at all.

The reverse is the other trap: when trump is led, the left bower must be played to follow if it is your only trump.

02Penalties

The common penalty is 2 points to the opposing team, or 4 if the offender’s opponents were playing alone. Some tables instead award the hand to the opponents as if they had won every trick. The hand is usually stopped as soon as the renege is caught.
