After having another look at these posts, the following makes a lot of sense to me:
1.) In a 2/1 GF auction e.g. 1♥ 2♣ 2♠ both partners should first bid out their hand shapes. I don't see any reason why the 2♠ bid should be regarded as a reverse bid.
2.) If you want to jump to show a "true reverse bid" all you are doing is taking up your own bidding space.
3.) Once you have established a suit fit (might be on level 3 by now), can't you show extra values for a slam try via Serious 3NT? Or if you play Frivolous 3NT, start cue-bidding on level 4 to show extra values and slam interest?
You seem to be arguing that you should ignore strength, and just bid cheapest natural suits, so with 1♥
opener could have a 12 count 45xx hand. I would argue - as does EricK - that if you have an agreement that a 12-14 hand will repeat his major (1♥
) then this loses nothing in finding the fits : responder bids 2♠
if he has 4, or if not can bid 2NT so that opener can then describe his shape, bidding a second suit such as 2♣
, showing 3+ support with 2♦
, a 6 card suit with 2♥
, or none of these with 3NT. Nothing is lost. Conversely, if opener's first rebid is 2♠
by these methods, it has to be 15+. It gives information on strength, as well as shape.
This helps, because the use of serious/non-serious 3NT only applies with a major fit. Let's say there is no such fit.
With my sequence 1♥
2NT 3NT responder with his 16 count can happily pass. Opener has no more than 14. With my sequence 1♥
2NT 3NT, responder knows opener is 15+, so with his 16 count can bid 6NT after checking for aces - using Gerber or asking specifically for 5 aces in hearts or diamonds if that suits his hand (with a kickback method). The correct contract always.
With your sequence 1♥
2NT 3NT, responder is stuck with his 16 count. If he passes, opener turns up with 16 and you miss the slam. If he bids further, opener turns up with 12 and you have bid too high and go off.
It also works better if opener supports the minor. For you, 1♥
is any strength, and you don't know what to do. Look for a slam, and you may too late find out that 3NT was the best contract. For me, 1♥
shows diamond support, but only 12-14, whereas 1♥
So I will argue there is great benefit in not bidding shape immediately.
