North opens 1 and South, with 16 points, responds 2, forcing the partnership to game.

North has a minimum strength hand, but with a 6-card suit he rebids 2.

Opposite North's 6-card suit, South's doubleton is adequate support. If South had a minimum for her 2/1 response she might just jump to 4 to show no interest in slam. With a little extra she bids 3 since she knows the bidding cannot stop until game is reached. From South's perspective North might have a big hand; his 2-level rebid shows suit length but does not say anything about strength. This is one of the beauties of 2/1, the bidding can be kept low while you look for the best place to play. However, this time North merely bids the game and South passes.

The hand would have been bid the same with or without 2/1.
