If the clubs are with LHO and diamonds are with RHO, there is no squeeze. After the prescribed play, I would cash cK (in case one shows out, then a club finesse can be made), then cQA. - If the cJ is outstanding with LHO, then the only way to make is if he has long diamonds as well (LHO having hQJ is quite far-fetched, he might have led it). So cash all majors ending in hand and hope for the best. - If the cJ is outstanding with RHO, then, -- if the diamonds are with LHO, there is a double squeeze, and this requires cashing the diamonds early to squeeze RHO in the rounded suits); -- if the diamonds are with RHO, there is a simple squeeze, and this requires NOT cashing the diamonds early to preserve entry. Alas, there is no guaranteed way around this. By vacant spaces, LHO is likely to have length in diamonds, so play for the double squeeze. Edit: Of course this is besides the fact that 12 tricks is always available if diamonds are 3-3, no matter what the play is.
