Bidding Problem
Partner has made a help-suit game-try, saying that he was too strong to pass out two spades, but not strong enough to jump to four spades. He particularly wants you to look at your holdings in the black suits. And here your hand could not be better. You have a double fit in the black suits, and advocates of the Losing Trick Count will see that this hand has only eight losers (two spades, three hearts, two diamonds and one club), when a standard single raise indicates nine losers. Instead of jumping to four spades, you should raise to four clubs. This says that you have the values to jump to game and that you have a super hand for the auction with great black suits.
If partner holds something like:
 A Q 10 5 4 
A 8 3 
 A 
J 9 8 4 he will settle for four spades.
But if he holds:
 A Q 10 5 4  A 8 3  7  K J 9 4 then six clubs, but not six spades, can be made, the diamond ruff in your hand being the twelfth trick.
Card Play Problem
It should be clear that your partner, East, has few values. He cannot hold the king of spades or ace of clubs, unless South has taken a big gamble.
So, you should hope to take these four tricks: two spades, one diamond and one club. But to get those spades, you might need partner to lead the suit through declarer.
South draws trumps and plays a diamond. Rise with your ace and exit safely with a diamond. Declarer will take his tricks there and play a club to his ace. You must be ready — sacrifice the king under the ace. Then East must get in for the lethal spade switch.
Keep the king of clubs in your hand and you will be endplayed, forced to lead a spade or concede a ruff-and-discard.
