You hold: ♠ 7 ♥ AK10753 ♦ QJ7432 ♣ -

It would be nice to show both your suits in one go. Some partnerships use a jump to four of a minor here as leaping Michaels, showing that minor and the other major. Failing that, you can try three spades, hearts and either minor. You should be prepared to compete to the five-level on your own with this shapely a hand. My opinion is that leaping Michaels has far more upside than downside.
