Reading all the comments, no one recognizes the XX. What should your pd try to tell you ? Obvious a remarkable hand and asking what you can support. Pd already knows you have at least 5 spades so, tell him your best second card and that is : ♣ . The KQxx is in combination with the single and doubleton adds strenght to the hand. So, 3♣ should be the answer.
