After an uneventful bidding, West leads the ♠J. I followed my first attempt to just bet on underleading the ♠K, top of an inner sequence. But that is not a good was to handle the hand If West had the ♠K, you can just as well finesse it later. If he hasn't, your trick count is 8 and you are in trouble after the expected continuation of spades. My second idea is to duck once more. But nothing works, because East can always exit in diamonds and the heart finesse does not work at all. The best play is to duck lead and then cash the clubs, looking at the discards at East and West. Admittedly, one will still have to guess how the hands sits in the end. But East and West will fight to hold he diamonds or not which makes a heart finesse an effective throw in to East.
