The tough plays keep appearing

Salma Hayek said, "Life is tough, and if you have the ability to laugh at it, you have the ability to enjoy it."

This week has featured some tougher-than-usual plays. Here is another. South is in three no-trump. West leads a fourth-highest heart six, and East produces the king. What should declarer do?

The auction was natural, South's two-no-trump rebid denying four hearts. Note that if you play two-over-one game-force, South's rebid indicates 12-14 points or 18-19 points; there is no need to jump to three no-trump, because two no-trump is forcing. Then, with 18-19, if responder, as he does here, raises to three no-trump, opener nudges to four no-trump to invite a slam. (Some pairs play that to rebid three no-trump indicates a 5-3-3-2 hand with 15-17 points that did not look right for a one-no-trump opening.)
