From a team match with IMP scoring at a local club a couple of days ago:

Dealer: W
Vul: NS

---

I was playing basic 2/1 with a very good partner and we only got to 5♣.

6♣ was found at only two of twelve tables.

1d-1s
2c-3nt
4nt-6c

Alternatively, W could upgrade to a 3c rebid.

Seems hard to me. 3N seems the normal result.
On the left is a contrived and unconvincing auction.
Second thoughts:
Having read Helene_T's reply, I quite like her auctions.

This is a very sensible auction, I suspect ours would be much murkier than that after a 1♦-1♠-2♣-2♥-3♥ start and we'd end up guessing.

It's neat, but what are the constraints for selecting 3nt rather than an artificial 2♥?

Could happen to us too, and would probably end up in 3NT.
Although with those red suits I might stretch to a 3♣ rebid in which case it drops out quite easily:
1♦ - 1♠
3♣ - 4♣
4♦(control ♦) - 4N (RKCB)
5♠(2+Q) - 6♣
p.

My younger partner is capable of opening 1NT here which would also work for us:
1N - 2♣
2♦(no 5cM) - 2♥(spades)
3♣(misfit,max) - 3♥(clubs)
4♣ - 4♦(control ♦)
4♠(control ♠ !♥) - 6♣
p.

Our auction was:

1♦-1♠
2♣-2♥
2N-3♣
4♣-4♦
4♠-5♣

Nullve, don't you play 2H as 4th suit forcing in this auction? If so, 2N would not be the correct response. 2S should show 3 card support, not a doubleton. so I guess I'd bid 3D over 2H. The auction might continue:

1D - 1S
2C - 2H
3D - 3N
4N - 6N

I don't know if anyone is interested but I tried it in BBO and a few major computer bidding and playing applications. I couldnt get past 5 clubs with 2/1 but managed to get to a variety of slams with any number of other systems and software. I have forgotten exactly which slams and which apps but it seems 2/1 was the problem rather than the apps per se. I have to say I was surprised with some of the slams including the way different systems treated quants Wbridge got to 6 clubs with SEF, WBridge and SAYC. QPlus got to either 6NT or 6C with Acol or whatever, but I think stopped at 4 or 5 somethings in 2/1
