You could try bidding 4
and partner might find a 4
call, but you are still a long far from home.
This hand, with only five losers, has plenty of potential. Having said this, it needs specific cards: the club king, the top trumps, and a diamond control. It is difficult to find all of this in standard methods, especially when this is plenty of hand outside of partner’s first-bid suit. But partner might have the right cards, with little in hearts.
The solution is the “serious 3NT.” Or at least an encouraging or waiting 3NT. We play that a cue bid in a suit bid by the partnership is an A or K, interchangeably. It is never shortness. 3NT gives partner a chance to show the
K, and you have an easy control bid of 4
.
Partner will then have a set shot, holding:
A K 5 4
J 7 5 3
K Q 4
K 2.
You might contrive another auction to slam, but my guess is that few would bid it without the 3NT convention. When 3NT cannot logically be natural, it is waiting and encouraging.
