Some safety-plays can look crazy

Jackie Chan, an action film star who hails from Hong Kong, said, "American stunt men are smart - they think about safety. But in Hong Kong, if you've got the guts, you do it. All of my stunt men have gotten hurt."

At the bridge table, we have safety-plays. Their aim, usually, is to ensure at most one loser whatever the lie of the missing cards in that suit. Experts know a lot of them; less capable players know far fewer. But, of course, often a safety-play proves unnecessary, because the distribution is docile.

The safety-play that is needed in this deal looks so strange that many would never even think of it. How should South play to guarantee making six no-trump? West leads the spade 10.
