98 CORRECT CONTRACT BRIDGE
Z made a sound opening bid of i-Heart; A's informatory double was sound and showed at least
five assisting tricks for a response in at least two
suits (Either spades or diamonds); Y's shift to 2 -Clubs was a questionable bit of strategy, as his pass
would have shown lack of assisting strength for
hearts. B's voluntary response of 2-Spades left no
question in his partner's mind that game was probable and A ended the contracting with 4-Spades,
which were readily made. Just because B felt satisfied that Y would not do well at clubs gave him no
excuse for failure to declare spades. Had B passed
Z would have rebid hearts and A would not have repeated his double; even had B bid 2-Spades on the
second round A would hardly have ventured to
raise that make, especially if Z failed to rebid, because B's failure to at once declare his spades would
make it appear as if game could not result from a
secondary bid.
