that queen and ace of diamonds is really neat too;
if you were to go last, and someone led with diamonds, you can get both of those cards to be books.
I call it b***tching. If the other team plays a king, you play the ace, and then lead with your queen. if they don't play the king, win the book with your with your queen.
If you ended up winning with that queen of hearts when your partner threw out a jack, you should go to the king of hearts so that you could cut those hearts later and make sure nobody else is cutting hearts.
