that hand is much too strong for 3♠ and just strong enough for X+diamonds.
Why? If it had been much weaker you would just have overcalled 2
♦, wouldn't you? I think the jumpcue should be reserved for hands that are too strong for a simple overcall an not flexible enough for a double.
A minimum 3
♠ should look something like
x
QTx
AKJxxxx
Kx
Or even less, if you don't mind having semi-stops (JTx in hearts anyone?). The maximum should be a hand that knows for sure that slam is not on under normal circumstances. The hand in question certainly does not conform to this criterion - almost every hand without a void in
♦ and
♥K and
♣Q (5hcp!!!!!!!) will produce very good chances for 12 tricks.
That said, I'm not very much into this thing. I just happen to think there are hands that warrant the jump cue by giving enough combined chances from a) reaching a makable, otherwise unreachable 3NT and b) preemptive reasons without being too strong for a two level overcall.
... and I can prove it with my usual, flawless logic.
