Comparable call after insufficient bid
South opens 1NT which is passed round to East who has 18 points and 5-5 in the majors. She bids 2C (Landy). West, with a 2-2-5-4 shape, bids 1D (insufficent) not accepted by North. West says that 1D was not natural (despite her diamond holding) but was meant to be 2D showing no preference in the majors. Does she now have any bid which keeps East in the auction? For instance can she bid a conventional 2D?
