Technical specifications

The lead card should be presented face down (invisible to other players).
Abide by this rule (compusary) in order to avoid being unnecessarily penalized in case of a lead out of turn. A face down lead card can be taken back without penalty...(If it was not visible).

Leading out of turn - summary
The player to the right of t he declarer (RHO) leads by mistake:

• If the declarer has played a card :
  • The lead must be accepted
  • The decalrer has implicitely accepted the lead by playing a card...He becomes the dummy !
• The dummy has started to show his hand (even if it is only one card)....
  • The lead is automatically accepted
  • The declarer remains the declarer
  • The declare plays from his hand in second position
• Nobody has played: The lead out of turn is acknowledged :The declarer has two options, he can
  • Refuse the lead : The leading card becomes "Principal Penalized" see below
  • Accept the lead and he can then choose
    • Either to remain declarer, the dummy then shows his hand, then the declarer will play in second position for that trick
    • Or to become the Dummy; Show his cards and his partner will play the contract

The Principal Penalized card
a Card becomes a Prinpal penalized card, mostly for an out of turn lead:

• Confirmed
• Refused by the declarer

The card will remain on the table exposed and be played on the first 'legal' opportunity. The declarer must then express his choice : he can :

• • Request that the lead be in the suit of the penalized card
  • Forbid the lead to be in the suit of the penalized card
  • In both of these cases, the penalized is put back in the hand of the player at fault that will be allowed to play it as he wishes
• The declarer can also allow the partner of the revoker to lead what he wishes :
  • the penalized card then remains on the table
  • The declarer will then be able to exercise his choice on the next round lead by the partner of the revoker
