Yet another query regarding insufficient bids and comparable calls !
West opens 4H as dealer. North, who hasn't seen the 4H opening, bids 1NT ( balanced, 12-14 ). The insufficient bid is not accepted by East and the bid is cancelled. North replaces the 1NT bid with 4NT. Is this acceptable ? It looks like it should be since, according to 27-B-1a :
"if the insufficient bid is corrected by the lowest sufficient bid which specifies the same denomination(s) as that specified by the withdrawn call, the auction proceeds without further rectification. "
However, without the 1NT insufficient bid, surely partner would take 4NT to be asking for the minors ? As the initial insufficient bid is not consistent with a 4NT overcall showing the minors, I would be inclined to think North does not have a comparable bid here. Am I right ?
