So what is a Crummy Dummy? It's a Bad Hand With a Big Suit. It's a hand that, unless it gets to name the trump suit brings nothing to the dinner table, not even a bag of peanuts. Here's an example:
♠ 8 5 ♥ K Q J 7 4 2 ♦ 843 ♣ 6 5
That hand is worthless unless Hearts are trumps. What about No-trump, you ask? The opponents, if one of them has ♥Axx can lock you out of the dummy just by holding up the Ace until your Partner has no more Hearts.
Today we're going to look at Crummy Dummies with six-card suits, which we call Weak Twos because we open them at the two-level. Here's exactly what it looks like. (As time goes by, we'll refine our definition, but this is a big enough bite first time around.)
First, you need a six-card suit that has 5 pts or three honors in it (there are other definitions, but we'll use that quality suit for the purpose of these lessons). You shouldn't have much more than one stray honor outside of your big suit.
Next, you need between 5 and 9 High Card Points (we don't add distribution).
Finally, no voids, no outside four-card majors and no two Aces. Down the road we'll talk about the philosophy behind that, but for now, trust me. (I'm from the government and I'm here to help you.)
The whole point of the Crummy Dummy (aka Weak Two) is to turn a worthless hand into a winner AND (wait for it!) by opening at the two-level, you are PRE-EMPTING all the bidding space and perfectly describing your hand. Pard knows EXACTLY what you have, so you don't need to bid again.
Let's try some examples and see how it works. Ready?
