[Kalvan14]

The normal opening bid is 1♦, with a 4-4-3-2 shape [either in 2/1 or SAYC].

With advancer's hand, my strong preference is double: it promises 4 cards in hearts, but values are good, and the posted hand plays well in a Moysian fit.
1N without a stopper and submitting a possible stopper in partner's hand is not for me. 2♣ shows a weaker hand. 2♠ is too committing [you've to play 2N or at 3-level]. 3♣ [in 2/1, 2NT shows a weak raise in clubs, and 3♣ is the invitational raise] does not fit this hand [good defensive values, and balanced hand; not to mention just 4 clubs].
