The finesse
Step 1 of 5
One honour, one finesse
You hold the king and one small card in dummy, and three small cards in your own hand. The ace is missing. If you lead the king out, the defender with the ace takes it and your king is gone for nothing.
Instead, lead a small card from your hand towards the king. The player on your left must choose before dummy does. If they hold the ace, they must either play it on your small card or watch the king win.
Take 1 trick.
Dummy
Lead from either hand.
Play a card from either hand, the way you'd play it at the table. Nothing here is scored, and you can start the suit again any time.
