North opens 1♠, the higher ranking of the two 5-card suits.

South, with 14 points, responds 2♣, forcing the partnership to game.

North now bids his suit.

At this point South figures North for 5 ♠s and 4 s. South cannot support either of North's Majors, but with a good stopper in the fourth suit bids 2NT. The game force is still on and North may not pass this bid.

North bids 3, indicating that this is also a 5-card suit. Now South can bid the game, knowing there is an 8-card fit.
