Smith signal

Smith signal

The Smith signal (also known as Smith echo or Smith Peter) is a carding-signal showing additional values (or lack thereof) in the first suit led by the opener, while the signal itself is given in the first suit played by declarer.

"Example:"

: Against 3NT, West leads Spades5 to East's Jack and declarer'sKing. Declarer then attacks Diams to establish the suit and West wins the Diams Ace on thesecond round. Now, how can West know who holds the Spades Queen? Playing the Peter Smith signal, East plays high-low in Diams to show the Queen ofSpades or low-high to deny it.

There are several variations, depending on partnerships agreement, as to exactly when this signal applies.

It can be played either against NT-contracts only, or against all contracts. It can be used by both players, or used only by the opener, or used only by his partner.

And it can be played either as described above, or "upside-down" -- i.e. low-high shows values in the opening-lead suit, while high-low denies it.
