Double Finesse

Sometimes we have multiple non-equivalent threat cards, and we can finesse against multiple opponent cards.

Here our queen is a threat against the king, and out ten is a threat against the jack.

Lead ♠4 and play ♠10.

Unless East produced the ♠K, later lead the ♠6 and play ♠Q.

We will make 2+ tricks in the suit unless East has both missing honours – a 75% chance.
