Table Manners –Playing the Hand.
As Declarer, you should call for the card you wish dummy to play; do not touch the cards on the table; do not touch any cards while deciding (dithering) about what to play.
When play commences, do not detach a card from your hand until it is your turn to play. Do not pull up a card, push it back into your hand, and then pull up another card. Never rearrange your hand when you are out of a suit. All these manoeuvres provide unsolicited information.
Do not look to see the place in his hand from which another player pulls a card, nor draw inferences from them.
Once a trick has been won and the lead made for the next trick, it is not permissible for any player to point out that a card is wrongly pointed (turned the wrong way). You are responsible for keeping track of your winning and losing tricks.
You are not permitted to ‘take a quick look’ at tricks previously won or lost.
A player can re-examine his last card played until the lead is made to the following trick. A player who has not yet turned his card over may request all cards just played to the trick to be refaced. Get into the habit; don’t face your card untill you are ready to play to the next trick.
