Hearts is a trick taking game in which the object is to avoid winning tricks containing hearts; the queen of spades is even more to be avoided.
The first card played in the first trick is the two of clubs. Play continues clockwise until everyone has played a card. The highest ranked card in the initially lead suit wins the trick. You may lead a heart at the beginning of a round only if you have only hearts in your hand or if hearts have been broken. Hearts are broken when anyone plays a heart when they cannot follow suit.
