Your Pard opens and you've got 10-12 pts. It's easy to respond with a minimum hand. We either raise Pard's suit (remember our Wonderbra Rule? Support with support), name a new suit at the one-level or make the Desperate 1 No-trump Response.
With 13-plus points, we get to game.
But what about The Middle Child? More than minimum, but not enough to game. Well, here are our choices. We can raise Pard's suit, leaping a level. Or we can name a new suit. That's not so hard, is it?
