SOME CONVENTIONS

 

Even if you do not use them with your partner, it is useful to understand what your opponents are saying to each other.

 

CRO means that the first bid shows two suits of the same COLOUR, the second bid shows two suits of the same RANK and the third bid shows two OTHER suits. An alternative name would be CRASH, meaning the third bid shows two suits of the same SHAPE.
