This suit combination came up at Bramhall & Cheadle the other week.
You have plenty of entries to both hands, how do you play?
If you start with the jack you will lose a trick when East has the singleton king and West 9765.
So start with a small card from dummy and finesse the queen (or ten).
If that holds return to dummy and play the jack. This will still pick up K9xx with East.
