which bid are you thinking of which says that? ok, if you're playing an unbalanced diamond you're obviously in a superior , but still dubious, position, because you can play a 2D or ideally 1NT rebid as showing hearts, so at least you'll not miss your 44 heart fit.
The bid depends on whether the partnership is playing natural continuations or an artificial reply (different partners, but 1
♦ is 6+ card or has singleton/void elsewhere).
NATURAL : 1
♦ 1M 1NT=3-suiter short in M
ART : with this method, a reply of 1
♥ is less than invitational with either or both majors, while 1
♠ = any invitational or better.
1
♦ 1
♥! 1
♠ = 3-suiter with spades, or 4x6x, and if responder has spades he raises, if he bids 1NT/2
♣/2
♦, opener knows he has hearts and will support. Responder can also rebid 2
♥ with both majors in case opener's hearts are better than the spades.
1
♦ 1
♠! 1NT!= ANY 3-suiter, then 2
♣ asks with opener bidding the one beneath the shortage, or responder rebids 2
♥ with just a bare invitation and both majors.
But I don't think it matters what methods you play providing 1
♦ has a shortage, because it will always be easy to find the fits.
