I just wanted to share an interesting (funny??) bidding sequence that I used recently with my regular partner in a local club tournament.

The normal sequence with standard conventions would probably have been

1H - 2NT (Jacoby)- 3S (short)- 4NT (KC asking) - 5D (0 or 3) - 6H (no need to ask for the Q with one ace missing)

We have modified our system to bid hands that are the same strength as 2NT but with a singleton or void to be 1H-2S ( it can also be 5-6 hcp still with 4-card H, a sort of semi Bergen block.
This allows us to bid splinter with 9-11 hcp with no particular interest in slam.

We also use 4S for KC asking in H when there is no possible ambiguity.

Finally we use a five steps answer to KC asking where the fifth step is 3+Q (second step is 0 possibly with Q or 3 without Q)

So our bidding sequence went

1H - 2S - 3S - 4S - 5S - 6H.

Needless to say that we alerted and explained the bids to our opponents, lest they think we had lost our mind...

I've also added more responses to my RCKW structure, also adding to the mix 2+ void into the 3/0 response for weak openings.

A nice spade sequence, 4 in a row. I could nearly do that (2♠ is jacoby for me and can show a shortage later) but we would bid 3NT after 3♠ to see if the shortage was void or singleton before ace asking with 4♠. How does your asker know whether the missing ace was not in spades with that offset by a spade void?
