Three great cards

[JLOGIC]

Natural 2N seems pretty important to me in these (3 suits bid) auction

[Zelandakh]

Did you notice it was a reverse Justin?

[JLOGIC]

Yes. I am just generally skeptical about systems where a NT bid is artificial and not showing a stopper when 3 suits have been bid, they are likely to lead the 4th suit so I think rightsiding NT is important. I wouldn't like bidding 2N with nothing in spades.

[Zelandakh]

Do you also play a natural 2NT in 1m - 1♠; 2♥ auctions? The arguments are similar there but space is now so short that it seems like a bad idea. Also, after 1♣ - 1♥; 2♦, for us not to have a fit we must either have 5+ hearts or be 4=4=3=2. Perhaps it is not ideal to bid 2NT followed by 3♠ (to deny a stopper) with that hand but we should at least end up in a playable spot. You could use a direct 3♠ (over 2♦) for that too without wrong-siding (a la Rubensohl) although I quite like the idea of using that as a void splinter.

Yeah I prefer to just play 2S weak over 2H reverses, with 5 spades and a spade stopper I would bid 2N and with 5 spades and no spade stopper and no fit I would bid the 4th suit. I don't play that much natural anymore but my last 3 natural partners all played this so maybe it's catching on :P

 

While that is obviously non standard I did think it was pretty standard to play 4th suit as weak over 2D reverses and use 2N as nat.

After 1♣-1M-2♦, as long as one does away with the obsession about majors, you can do the lot:

 

2♥ = artificial, showing invitational values (usually 7-8, but can be GF with hands that don't want to get pard excited). Over this, opener bids 2♠(art) or 2NT (nat), with minimum reverses, and everything at the three level is GF.

 

2♠ = artificial, very weak response (max bad 6). Opener can bid 2NT or 3♣ unless super-strong

 

2NT = nat, weak, but promises five cards in the major

 

3♣+, GF

 

The main thing you get is the extra layer (weak, inv and GF) as opposed to the usual weak/GF arrangement. This allows a slightly more relaxed approach to reversing with decent 4-6 hands with 15 points. But you also get more natural 2NT bids for your money - we don't always have a fit or game after reversing.
