How to Signal with First Discards

When you cannot follow suit and are forced to discard a card from a different suit, your very first discard is not just a throwaway—it is your most important defensive signal. In standard signaling systems, your first discard shows your attitude toward the suit you are throwing.

• A high card (e.g., 8 or 9) encourages the suit, telling partner: "Please lead this suit when you get the chance."
• A low card (e.g., 2 or 3) discourages the suit, telling partner: "I have no interest in this suit."

Why first discards work

Defenders must race to establish their winning tricks before declarer sets up theirs. Because defenders cannot see each other's hands, they rely on signals to find the vulnerable spots in declarer's armor.

When declarer runs a long suit and forces you to discard, throwing a distinctly high card points partner directly to your strong suit (e.g., an A-K or K-Q holding). Without this signal, partner might guess wrong and lead into declarer's strength when they eventually win the lead.

A worked example: Encouraging a shift

Declarer is cashing a long string of Spades in a No-Trump contract. You have no Spades left on the third round.

Your Hand (East):

♠ — (Void)

♥ A K 10 8 4

♦ J 6 5

♣ 9 3 2

The Play:

Declarer leads the ♠A. You must discard.

Caption: You desperately want partner to lead a Heart when they gain the lead. From your Heart holding, select the highest card you can safely afford to throw: the ♥10. Partner will see this unusually high card and immediately recognize it as a strong encouraging signal for Hearts.

Four common mistakes

• Throwing a random middle card (like a 5 or 6) that partner cannot confidently read as high or low.
• Signaling enthusiastically with a high card when your suit is actually quite weak, misleading partner into a fatal switch.
• Throwing an important winning card (like a King or Queen) just to make a "loud" signal.
• Failing to watch partner's first discard while focusing solely on your own hand.

When the rule does not apply

If you and your partner have agreed to play a different discard system—such as Lavinthal (McKenney) where the rank of the discard asks for a specific other suit, or Odds/Evens (Roman discards)—standard attitude does not apply. Always confirm your discard agreements before playing.

Key takeaways

• Your first discard is an attitude signal.
• High card = "I like this suit, lead it."
• Low card = "I do not like this suit."
• Ensure your high discard is clear and unambiguous (e.g., an 8, 9, or 10).
