Courtesy raise after forcing NT?

[david_c]

But you lose the option of signing off in 3C with a long, weak minor, say

x-x-xxx-AJTxxxxx

Indeed you do. I don't think this hand is worth worrying about, on grounds of frequency. Though perhaps 1♠:3♣ should be a weak jump shift (see next paragraph).

 

On the other hand, 1M:3C are used by many (including myself) as artificial raises, so the use of the immediate 3C response for weak or invitational hands wit a long minor is not available.

Serious partnerships might wish to treat a 1♠ opening differently to 1♥. Having lots of immediate raises available is very useful over 1♥. Raises are still useful over 1♠, but less so because you're guaranteed to be outranking the opponents' suits. Meanwhile, constructive bidding is harder over 1♠ than 1♥, so using jumps to show non-fit hands makes a lot of sense.

 

Besides, the use of 3C as good bad would be unoptimal when opener's rebid is 2D or when bidding goes 1H:1NT:2H; in that case, the most efficient puppet bid is the first unbid suit at the 2 level.

Yes, you should use 2♠ as good-bad after a 1♥ opening. My suggestion of 3♣ only applies after 1♠. I don't agree about 1♠:1NT,2♦. Sure, 2♥ is the most efficient puppet available, but it's also the most efficient way to show hearts!

This is an 8 looser hand so 3♥. The singleton in pd's suit is bad news but I have some useful intermediates.

 

3♥ would have been GF so pd can be quite strong. 11-17(18). But you have most of the same problem without the forcing 1NT, since there are minimal hands than would rebid 2♥ even if 1NT is non-forcing. At least, some partners do.

 

So this is more a case for playing limited openings than a case for not playing forcing 1NT.

Thinking about it,

I am more inclined to use 1S:1NT* as SEMIforcing, so that hands that would not accept any invitation would not rebid.

 

It seems to me that this might solve the problem, since after 1S:1NT:2H/S, an invitational responder just bid game, hence any 3-level suit bid by responder is signoff.

 

 

The 2 difficulties left are:

 

1- missing an 8 card major fir when responder is very weak or invitational with 3 card support

 

2- the way responder shall force to game with a long minor and an invitational hand: if he just bashes to 3NT, sometimes he will go down when 5m is cold; if he just bids 4/5m, sometimes a laydown 3NT will be missed.

 

Comments ?

Adam, could you explain how 2/1 and forcing notrump change this situation? Would opener ever pass 1NT playing SAYC with 5-4 in the majors? I agree with your comment that forcing 1NT is not pretty, but it seems to me that there is no difference for this particular situation.

There is a significant difference if 1NT is not forcing for one round. Opener will still bid 2♥ of course, but now you can distinguish between a sound raise and a weak raise (not invitational). Many play it this way:

 

1MA - 1NT

2OM - 2NT = sound raise in OM (other major).

 

Whereas 3OM would show less than invitational values; a courtesy raise if you like (in case opener has a super max for his 2OM).

Roland, I am confused: :unsure:

 

do you suggest this sequence if 1NT is forcing or if 1NT is NON forcing ?

 

If 1NT was forcing, doesn't this also sacrifice the natural 2NT invite ? :unsure:

Indeed. If playing 2/1 where 1NT is F1, 2NT next would be natural (11-12). If you play sayc or Acol, however, where 1NT is limited to a bad 10 count, you should use 2NT as a sound raise for opener's second suit.

Mauro, I like semi-forcing 1NT a lot. However, I think you still have to allow opener to bid again with light distributional hands; otherwise 1NT can just be too bad of a contract.

 

About the invitational hands with a long minor: Easy, play invitational jump shifts. :unsure:

The problem seems to be: "If I have to raise to 3♥ on hands like the one in the example, how does partner know when I have something like this versus a 'real' invite?"

 

This is easy in a non-forcing notrump system. There is no 'real' invite, because that hand starts with a 2/1 call. The raise is always something like 8-9 high with decent cards.

 

The answer I hear from most 2/1 players is: "I would just bid game with the 'real' invite, so a simple raise is basically courtesy." This may be making the best of a bad situation; automatically bidding game with all limit raises might work out okay, but I doubt it's better than showing a limit raise and letting opener make the decision.

 

Yes, this is also easy in a limit-opening system, or using something like riton or gazilli. There the answer is "the raise is always a real invite, because I don't make courtesy raises (if partner was strong enough to accept a courtesy raise he'd open strong ♣ / rebid 2♣)."

I believe that with this hand it is reasonable to invite even opposite a 10-15 opener

I agree, in a strong club context I would still try 3H.

I would pass, especially if partner can jump to 3♥ with a 5-5 maximum.

 

We have at most 23 high, and only an 8-card fit (if we have a nine-card fit then we have only 21 or so high at best). The diamond JT are unlikely to do anything for partner. The singleton is opposite partner's suit, which is often not best. If partner has the best possible hand, 4♥ will probably be around 50%. But there are lots of hands where 3♥ will go down, or where 4♥ will be bid and go down.

[Trpltrbl]

Very simple rule, I have a fit and decent ( more the minimum ) hand. So I raise to 3♥.
