I don't think partner is barred from pulling with a sub-minimum, a singleton diamond, and a bad club holding - say if he has your Qxx xxxx x xxxxx example hand.

However, more importantly I just think 2-4 hcps for partner are so rare in general that we shouldn't cater to them too much. Just because I might raise with the hand above doesn't mean I consider my range to be 2-10 and that I have to double 2N with every good 7 count - I would still expect a good 8-count or better for a double.

Also, RHO is a passed hand and LHO didn't bid over 1♠ - another reason to expect partner to have some values. Finally, the ♣65432-example hands are starting to irritate me - if partner has 5 clubs, the chances are pretty good that his best club will beat the 5th-best club of LHO. Maybe even the 4th-best club of LHO's 5-card suit! I don't think most LHOs need ♣KQJ here to bid over 2♠.

Double. If partner has sub-minimum and short diamonds, he runs. That is not lack of trust, it's a logical consequence of my failure to make a game try. Playing me for ♦KQJT + A + A is not practical.

 

The actual responding hand has a clear 3♠ bid.

I don't think two queens and a jack is too much to make a preemptive raise.

True, but J10x Q10xx x Q9xxx would, I assume, be a 2♠ bid, followed by a pass, followed by another pass.

 

Anyway, if 2♠ is a classic european (5)6-9 raise

Do you actually know anyone, in Europe or elsewhere, for whom the lower limit of such a raise is "(5)6" when it contains a singleton?

A few. <_<
