In theory, with our current agreements he would bid 3♥ (advance control-bid) and then if I bid 3NT pull to diamonds to make things clear.
If he bid 3NT I would pull to diamonds.

But I can see a case for his 3♥ being a simple control-bid confirming diamonds and denying interest in 3NT, 3NT to play and 4♥ being kickback.

I think 3H is clear over 3D
I now rebid 4D,

Now I hope partner takes me for a heart control and bids 4H, KB
4S,=3
5C by partner showing all the keys, QD, KC, denies KS,grand interest
7D by me.


Very interesting thread how playing somewhat similar bidding systems results in different auctions.

Good thread

It's semi-artificial. Might not be 5+ clubs with some reason, such as diamonds or balanced with no 4cM.

I like this use of 2 clubs. But surely with such a bid, you have agreed the meaning of all second responses after partner has bid a second time, right?

So what are we trying to do asking what the second bid of this hand should be, why not check your system notes?
