This document provides an overview of signalling in bridge, specifically covering two schools of thought for signalling - standard signalling and Upside Down Count and Attitude (UDCA). Standard signalling involves playing high cards to encourage and low cards to discourage, and using high/low cards to signal even/odd counts. UDCA inverts these signals so low cards encourage and high cards discourage, to avoid discarding potential winners. The example shows how the schools would differently signal with spot cards after a lead of the ace. For discarding other suits not being trumped, the document recommends using an odd/even system where odd encourages the lowest unplayed suit and low/high even encourages the lower/higher unplayed suit.

- 3. Motivation Behind SignallingIn general, spot cards (non-royals) are quite useless for the defense, unless they’re trumpsSignalling makes use of these spot cards and allows the defense to have more insight regarding their partner’s hand
- 4. Two Schools of ThoughtSchool of thought 1: Standard signallingSchool of thought 2: Upside Down Count and Attitude (UDCA)
- 5. School of Thought 1: Standard SignallingWhen following to partner’s lead, low card = discourage, high card = encouragei.e. playing a low card following partner’s lead discourages partner from leading again. This is most commonly used when partner leads an AceWhen it is less useful to show attitude (encourage/discourage) e.g. when opponent is running a suit in which you have no stoppers, you can show count insteadHigh card = even number of cardsLow card = odd number of cards
- 6. School of Thought 2: UDCAUDCA users contend that there is no reason for you to throw away high cards in suits in which you have royals because high spot cards may eventually become winnersUDCA users thus invert all the signals in standard signallingLow encourage, high discourageLow even, high odd
- 7. Example of Difference Between Standard and UDCAWhen partner leads A spades holding 8 and 3 of spadesStandard signallers will discard the 8 first and then the 3 on the K. Partner will then know to lead another for you to ruffUDCA signallers will discard the 3 first then the 8 on the K.
- 8. Discarding Other SuitsStandard signalling and UDCA only apply when you are following to a lead. What of discarding other suits (not trumping)?The system that we have adopted is the odd/even (O/E) system. There are many other systems but we feel O/E is the easiest to pick up and serves most purposes
- 9. O/E SystemDiscarding an odd card encourages that suitDiscarding a low even card encourages the lower of the 2 unplayed suitsE.g. partner leads hearts and you discard 2 of spades. You are encouraging clubs (lower of the 2 unplayed suits, which are clubs and diamonds)Discarding a high even card encourages the higher of the 2 unplayed suits6’s are ambiguous, though the meaning can usually be discerned by the presence of even cards in dummy/your own hand
