Contract:
4♣ by South
Lead:

(Partner's 3♣ shows exactly 4 cards, with unspecified point count.)
We paused to think about neither opponent bidding hearts, and worked out that that West's distriubution must be 5512 and East's must be 0562.
So, we know West's spades and East's diamonds exactly. We don't know where the heart honours are, but East's bidding was very weak for the distribution, so she may have only 9 points. The hands must be something like those shown.
Plan the play to guarantee ten tricks.
