First Answer
You (3rd seat, both vulnerable) are declaring. The opening lead is the four of spades (partner’s suit).
Repeat Question 1
What’s going on in spades?. You were expecting a club lead (the unbid suit) so perhaps this is a singleton.
What’s your plan? Perhaps you missed a slam, but you can’t do anything about that now, so focus on declaring as well as you can. You should notice that you need to ruff some clubs in dummy. So you win the Ace of spades, play a club to the Ace, and ruff a club in dummy. Now a diamond to the Queen and another club ruffed in dummy.
Now what?
