Just out of curiosity, would anyone mind suggesting a hand that was not good enough to open 2♣ but over a 1-over-1 response now has the abilitly to ask for controls and force the auction to the 5 level?

I don't disagree with the suggestions that 1♦-1♥-4♠ should be exclusion RKCB (or kickback if it has been agreed that 4NT is exclusion), but I would like to see a hand that fits the bid.

Against me recently Polish Champion Cezary Balicki made a grand slam force on something like:

♠ ---
♥ AKxxxx
♦ xxxx
♣ Axx

When his partner had simply made a non-forcing (negative-free) bid in diamonds.

I saw a similar hand, not quite as strong as those posted above, but which upgrades greatly when partner hits their suit.

♠--
♥KQxxx
♦AKQJxxx
♣x

1♦-1♥
4♠* (ExRKC)

Exclusion in spades seems like just what the doctor ordered. Even with a little less shape it merits a slam try of some sort:

♠--
♥KQxxx
♦AKQJxx
♣xx

1♦-1♥
3♠* (splinter)

intending to continue with a 4♠ cue if partner declines your first invitation.

4♠ = rolling kickback G*****

Sometimes a hand that is technically strong enough for a 2♣ opening will make a 1-level opening because it has 2 or 3 suits to show and fears pre-emption.

4♠ directly after 1♥ is EKCB. 3♠ and then 4♠ is a splinter then cue bid showing a void, interested in slam but not able to use keycard (maybe it missing a side-suit control or something).

I think the 4 Spade bid sounds like a pretty normal cue bid agreeing to Hearts as trump and promiseing first round control of Spades (singlton or void).
