(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 5-5-1-2 and East's must be 0-5-6-2.

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.
