Partner's 1♣ is not-quite-full-Dutch-Doubleton, showing any 12-13 or 17-19 balanced without an outside 5-card suit, any 11-23 unbalanced hand with primary clubs or any 4144 or 4414 in that range. 2♣ clarifies that partner has got an unbalanced minimum with 5(+) clubs (only 5 if 4♦5♣ and too weak to reverse). 3♦ is natural. Do you agree with the bidding thus far, and what is your plan from here?
Edit: I just noticed I mistakenly put both of these in the General Bridge Discussion forum, rather than the Interesting Bridge Hands forum. I'm sorry. Could a moderator move these to the proper spot for me?
