So, here is the hand, and the double-dummy showing that on the lead I should make an extra trick.
The part that interests me is how to get here.
FWIW, the hand evaluator gives this result: K&R (A KQJT985 AT3 J7) = 18.00; DK = 15.
One reason that I dislike 2♣ with hands like these is that when I'm LHO or RHO I will always jump in with an annoying bid at any vulnerability.
(8320 1732 2173 2344) The shape is also quite interesting in that despite the unusual length in three suits the remaining cards are normally distributed in the other hands.
