  Overtake partner's ♣K with the ♣A.

You are pretty sure partner would not have supported your ♣s unless he had 4 of them, which means it is very likely that South has a singleton. (he might even be void)

So if you are to set this contract partner is going to have to have some ♠ winners.
It might not matter, but it also might be vital that the first ♠ lead comes from your side of the table so after you overtake with the ♣A you switch to the ♠7.

Partner loves it - whatever South does West takes the next two ♠s, then leads a third ♠ for you to ruff. Down 1.
