J. B. Elwell, Advanced Bridge; The Higher Principles of the Game Analysed and Explained
“ If you deprive your partner of the information to which he is entitled, you rob Bridge of much of its intellectual pleasure. How can he know when the weak hand can “ruff” your suit? How can he tell whether a lead will force the strong hand or give it a discard? How can he count your hand or the dealer’s? How can he make correct end plays without knowing the position of the cards?Without this help to partnership play you are in no position to combat the dealer. It is not difficult to win tricks from adversaries who neither give, nor make use of information. ”
