First thought is win it, K, club hook. Loses only when LHO holds Q and another spade. If I duck, they can switch to a heart.

But how realistic is this switch? RHO holding KQJ9x(x) will almost certainly continue the suit; all the more so if he holds a heart honor which looks entryish behind AT73. Ducking would give safety against LHO holding two spades and the Q. Furthermore even if the club hook works, I will still need a favorable position in diamonds to take 13 tricks.

If I really think it through at the table I think I would duck.


edit: of course, if I knew RHO as a player who would never open 2 with KQJ9x, then no reason to duck.
Life is long and beautiful, if bad things happen, good things will follow.

I agree with "if you know RHO definitely won't open on 5 cards then just win Ace." I guess you might even argue that if there's less than a 36% possibility RHO has opened on 5 cards you should win the Ace, since those are (roughly) your odds of picking up a 13th trick in diamonds.

How would you plan to play for that 13th trick? If you lead clubs from hand you might find South with Qxx; if you cash the top diamonds before touching clubs, you might find North with Q.
... that would still not be conclusive proof, before someone wants to explain that to me as well as if I was a 5 year-old. - gwnn

With no information about the personality of south, I decided to win the 1st trick.
I went to the board w/K... and took the finesse.
The news was "sorta" good..... North won w/Q.

BUT back came a SPADE.... for Down 1 .

South had made a good 3rd seat opening with K Q J - 5th .
North
7 2
K J 4 2
10 7 5 4
Q 6 3

South
K Q J 9 6
Q 8 6 5
J 2
8 7

If I ducked, I doubt if South would have made the killing switch...
