Takeout, no other agreements

I assume it at least excludes fit or minors 5-5...
So probably 2=2=4=5 or similar, I think I Double although it could well be wrong.

I wish pass was forcing

Edit with the new information regarding vulnerability, 5H

Penalties ? also note the edit to the OP

This is not part of any bidding system or agreement that I personally have ever played but...

I think I will improvise with a 4NT bid as South.

* When, as expected, North bids 5♣ or 5♦, I will 'correct to' 5♥.
* Hopefully this shows a slam interest with a self-sustaining Heart suit.

North, a passed hand, will rarely have perfect cards & may well pass; occasionally with hands suitable for a slam.
However, North looks to have 0-1 HCPs in ♠ + maybe 9-10(11) HCP in other suits. With ♠xxx ♥A (singleton) and a minor with KQxxx or KQJxx, North should find 6♥, with a realistic hope that the minor suit is used for discards after declarer draws trumps.

We open fairly light, KQJxx and an ace gets opened. I thought about 4N but wasn't sure what to do next.

Correcting 5♦ to 5♥ can be a disaster, where do you want to play opposite xxx, x, KQJxx, Jxxx ?

Not correcting can be wrong opposite xx, Jx, Qxxxx, KJxx

[DavidKok]

The direct 5♥ is a slam try for me, while 4NT-then-5♥ is merely competitive.
If we bid 4NT and partner responds 5♣ all is well: we can pass with hearts and clubs, correct to 5♦ with hearts and diamonds, and correct to 5♥ with single-suited hearts.
If partner chooses diamonds instead we have a problem. Now both hearts+clubs and single-suited hearts correct to 5♥. It is better to lose this definition on the weak hand, that way partner will know to pass. If the slow route can be strong partner may have a very difficult guess when we correct.

5H.

If you have the agreement, you could go via 4NT (DavidKok seems to play it the otherway round), but at the
table I would just bid 5H.
As it is I am not too worried missing slam, given that p is a passed hand, yes slam can make, but I usually
dot go hunting for the gold, that can be found at the end of the rainbow.
