If LHO has a singleton K
♣, as in: Jxxx xxx xxxxx K, we are down as RHO can overtake K with the A and play another club for a promotion.
So we should be safe to ruff a club in hand ( with the T if it makes you feel better
) and hope that spades behave.
RHO is an expert, altho in these social games one's attention sometimes falters. I don't know if he thought this through but on any layout wherein LHO has a stiff club, there is no need to overtake the K and return the suit, and it would be a mistake to do so if RHO held, as he did, Jx in spades originally (thus a stiff J at this point).
Wesley got it right.
We are in dummy and we have to get to our hand to pull trump. We can do so either by ruffing a club or by cashing the second diamond and then ruff the 3rd.
Ruffing the club risks being overruffed if LHO had a stiff K, and the switch to that card, followed by a diamond, suggests that this is quite possible.
However, on all layouts on which he has a stiff club, he had either 5 spades originally, and now has 3 left and we cannot make, or he had 4 spades. If he had 4 spades, he is 4=3=5=1 and now RHO has a stiff diamond.
So on all hands where LHO has a stiff club, and it matters, we cannot hope to cash a second diamond. Like it or not, the only way back to the hand is a club and we HAVE to ruff with the 10. This is not to make us feel better, other than that we don't like to go down in a cold contract, as we would were we to ruff low.
If LHO had Jxxx xxx Qxxxx K, we can't make anyway. He actually held 9xxx xxx Qxxxx K.
Note that had RHO overtaken the club K to return one, any declarer with a pulse would know that LHO had a stiff club and would have no choice but to play the 10. Further, if LHO held the 10 of spades, then there was no need to overtake and return one....we're going to be in dummy next trick and will have no winning option.
