Is the ♣9 really such an automatic false card on this hand? RHO may have hopes for a legitimate diamond overruff/trump promotion - say he has ♣9xx and thinks partner may have ♣QT.
To me its not auto, but to me ♣9 is not auto stiff either.
Remember that when we play ♣ to our ace, we dont even know RHO is short in ♦ yet, maybe he played ♦ 9 and J from KJ9.
