3 ♣ by South

Lead: ♥ 2

Down 1 — NS −50

Here we see the first case of double of 2 ♦. I mentioned that double will include weak no trump hands. It will also include hands in a similar range with a long minor suit. There will also be various strong hands included as we will see later. 

After our double, west will nearly always make a pass or correct bid. I have assumed here that is 2 ♥ (or 2 ♠) or some jump in the majors. Some partnerships might play a different method.

After west bids 2 ♥ north's priority will be to get east to tell us what major they have. We will do this by frequently doubling with the balance of points - around 8+ hcp and either a balancedish hand or various game going hands. Here north doubles and east is forced to retreat to 2 ♠. Notice that east does not have much of a suit. I have just used random hands with a six-card major. I am not necessarily recommending the 2 ♦ opening here or on any other hand. However these are the hands that sometimes our opponents bid on. 

South's rebid of 3 ♣ shows a hand with around a 12-15 overcall. Usually with a poor holding in opener's major it pays to be conservative on these auctions. Therefore north should not push on to game. In the recommended methods south had the option with a good hand and a decent spade stopper to rebid 2 NT which would show a maximum double.
