South opens 1♠.
North cannot say 2 because he only has 11 points, and also because he only has 4 s. So he bids 1NT (forcing for 1 round).

South rebids 2♣, a 3-card suit.
North now jumps to 3♠, showing limit-raise strength.
This sequence is the way to show a limit-raise with only 3 trumps; an immediate jump-raise to the 3-level shows a limit-raise with 4 trumps.

In any case South has a bare minimum and passes the invitation.
