1C=1H
1S=2C
3C?

1c=3+
1s=natural, nonforcing and does not promise an unbalanced hand
2c=natural, signoff

What sort of hand/range do you expect for 3C?

4=6 or so in the blacks, 16-18 hcp: responder can have up to a soft 10 count for this sequence, so opener needs to be able to explore for game.

Agree with prior post. I would add that 2 and 2NT, and possibly 2 (if strict no 5-card spade suit agreed) would also show this pattern.

I would expect 2 to look like 4036. I would expect 2NT to show a diamond card (Ace or King) and two top club honors. So, 3 probably shows a lack of a diamond card.

Usually 4-6+, but I suppose a good 4=2=2=5 is possible too.

I would expect the strength to be similar to a 1N opener, but I'd do it with a lot of quick tricks and a great club suit too: AKxx, x, xx, AQJxxx.

Maybe I should even have a little less. Its not hard to construct a vanilla 2C response from pard that produces 11 tricks: xx, Axxx, xxx, Kxxx.

With 13-14 points, he has NO business looking for game after 2: he uses the magic word (pass... the most under-utilized call in bridge).

And 2 is NOT 4sf: it is patterning out, with 3 and extra values: 4=1=3=5, 16+

4SF is an ARTIFICIAL bid, made by responder, not a natural bid made by either partner. It either forces to game or for one round, depending on style and whether bidder is a passed hand.

I have seen a number of posters refer to opener's bid of 4th suit as a use of 4SF, but this is an error, in my view. Such bids are often merely patterning out (often carrying a message of extra values) or are mark-time bids, but they lack the artificiality that makes responder's use of 4th suit a conventional call.
