South opens 1♥ and North responds 2♦.
South has a good-looking hand, but needs to find a trump suit before she starts showing her extra strength, so she bids just 2♥.
Knowing that South holds 6 ♥s, North can support with the honor doubleton so he agrees the trump suit with a Fast Arrival bid of 4♥.
South has some extra strength, but not enough to push on after North's weak bid.
Notice that if South DID try a 4♠ Control bid North would just bid 5♥ and the pair might be one trick too high.
