A ruff needs careful planning

Howard Ruff, a financial adviser, helped popularize the proverb, "It wasn't raining when Noah built the ark."

Bridge has a faint connection with Noah because each side plays two cards to each trick, and more often than not, they will be from the same species - I mean suit. In today's deal, how should South play to make sure that he moors safely on Mount Ararat? The declarer is in four spades, and West leads the club jack.

North might have raised one spade to two. Then, South's two-club rebid was New Minor Forcing, which promised at least game-invitational values and primarily asked opener if he had three-card spade support.
