One game of Hearts followed from the deal to the finish, move by move, with the reason for each choice.
Four players — you, Ada, Bo and Cleo — are dealt thirteen cards each. On the first hand everyone passes three cards to the left. Your hand: ♠ A Q 4, ♥ K 9 3, ♦ J 8 6 2, ♣ 10 7 5.
Holding the queen of spades with only two other spades is dangerous: anybody leading spades can force you to play her. So you pass Q♠ and A♠ to Ada, along with K♥, your highest heart. From Cleo, on your right, you receive K♣, J♥ and 8♣.
You now hold ♠ 4, ♥ J 9 3, ♦ J 8 6 2 and ♣ K 10 8 7 5. With a single spade you will soon be void in the suit, and that means you can throw away hearts and high cards when spades are led.
Bo holds 2♣, so Bo leads the first trick. Play goes to the left: Bo, Cleo, you, Ada.
Bo leads 2♣, Cleo plays 9♣, and you play K♣. No heart and no queen of spades may be played on the first trick, so it cannot cost anything — a free chance to get rid of a high club. Ada plays 3♣, and your king takes the trick with no points in it.
You lead 4♠, your only spade, to make yourself void. Ada, holding the ace and queen you passed her, plays 7♠ under it. Bo plays 10♠ and Cleo J♠, and Cleo wins the trick.
Cleo leads 5♦. You play 6♦. Ada has no diamonds, so she can throw anything, and she throws the queen of spades. Bo holds A♦ and 10♦; either card beats 6♦, so he is taking this trick whatever he does, and he plays the ace to get rid of it. Bo takes 13 points.
Bo leads 10♦ next. Cleo plays 9♦ and you duck with 8♦. Ada, still void, throws K♥, the king you passed her. That is the first heart played, so hearts are now broken and may be led. Bo's ten wins, and he takes another point.
The rest of the hand is played out. With spades gone from your hand you throw hearts whenever you cannot follow, and you are caught for three points: a trick with J♥, 9♥ and another heart in it. Ada takes four hearts, Cleo three, and Bo, with the queen and three hearts, 16.
The scores after the first hand are you 3, Ada 4, Cleo 3 and Bo 16 — twenty-six points in total, as every hand has. Nobody took all of them, so nobody shot the moon.
Passing the queen with the ace of spades was right: Ada could not keep her, and she ended up with Bo, who had to win a diamond trick. Making yourself void in spades early gave you somewhere to throw hearts later.
The next hand is passed to the right, the one after that across, and the fourth is played with no pass. The game ends when somebody reaches 100, and the lowest score wins.
