You chose to play the 3 of Hearts. This is not actually incorrect, but I don't think it is the best choice under the circumstances. You don't have any idea what Hearts your partner has. Normally, you would play low when playing second to a trick, but in this case, you think there is an outside chance that you might have the ability to win this trick, and so playing low would be expecting your partner to win it. I think there is a better choice. Go back to Question 14 and try again.
