Can you speak another language other than English? If so, it would have taken time, studying, and learning before you were fully able to communicate. This is so with bidding in bridge. The more you play, the more you will learn and appreciate this language of bidding. This is a language that is based on logic and understanding. It is not sufficient to just learn the bids. You also need to understand why.
Find a favourite partner. This must be someone with whom it is easy to communicate. It will take a long time to build a good partnership. You will need to develop your system so that you both will know what is meant by each bid you make.
Get to know and trust each other. Remember never to criticise at the table. Find time after each session to discuss the hands you played. There will be disagreements, which will have to be resolved. It is important to finally reach agreement on even the smallest point. There can be no future in a partnership that cannot do this.
Every bid that is made should tell each other more about the hands in order to find the best contract.
Whatever system you decide to play, the following basic principles will apply. Keep to these principles in order to build up the trust you must have for each other.
