Preference signals
As a general rule, when you realize that showing count will not help your partner...You can give your cards played another meaning...
Conversely, your partner, understanding that count is not important for the defense should understand that your carding is showing preference.
This carding always calls for a suit other than the one played or trump.
- A high card calls for the higuest of the remaining suits
- A small card calls for the lowest of the remaining suitss
The simplest case : On the lead of an Ace by your partner, whan the dummy has a singleton, Your card will show preference !
