2♦ is a multi, weak only, 3-9 5+ cards in a major, how do you approach this ?
Your responses are 2♥ to play opposite hearts or bid 2♠, 2♠ to play opposite spades, or bid showing hearts, 2N strong ask, suit and range, 3m forcing, after 2♦-2♥-2♠ only 2N is discussed.
Partner will not be 5-4 in the majors as we play Ekren, but could be 6-4
