Do you mean 4N opener, or quantitative or Blackwood, answers differ

The auction was 1h- 4nt by me(blackwood) for play heart -5nt (?)-6h (by eye)

If you mean that 4NT was RKCB in hearts (which is one primitive agreement possible) then 5NT would usually show an undisclosed void and an even number of keycards.

effectively...That was the hand. Never seen before

Many people play straight (4 ace) blackwood on the first bid over 1♥ to cover cases like x, x, AKQJ10xxxx, AK where I don't care about ♥K, and bid something else first if they want to KC

4NT is a horrible bid with a void

Did you make it ?

[pescetom]

That hand fits, even keycards and a void. With odd keycards North would have replied 6♣.

South was foolish to keycard without describing his clubs and with a void of his own.

You can see a slightly more reasonable example in the "Better than the soccer" thread.

I think this really belongs in the advanced or expert forum.

My local club is full of intermediate players with a couple of players who were advanced in their heyday. I would be happy if they knew the continuations after RKCB (they don't) before they worried about void-showing responses, to which only some adv+ tournament players will have discussed with their regular partners.

In short, just within the topic of RKCB, there are more important areas to discuss.

We actually don't play the standard responses with voids.

Most important question to ask is whether (spades trumps), 4N-5♣-5♦ is 5♥ or 5♠ denying the Q
