Hi Wayne,

 

Limit Raise

 

1♥-3♥s is a limit raise as it is tightly defined and shows a hand with support and 10-11 points

 

1♥-2NT*(Jacoby) is a constructive raise as it shows a better hand than a limit raise (normally) with game going values opposite a minimum.

 

Constructive

 

1♥-x-2NT*(Truscott / Jordan) is a constructuve raise as it shows at least a limit raise and support.

 

1♣-2♣* Inverted Minor is also a constructive raise for example

 

 

Pre-emptive Raise

 

1♦-x-3♦ typically showing a minimum raise in Diamonds. So any raise in an attempt to block opponents bidding showing support.

 

Mixed Raise

 

2♠-x-4♠ to play may be pre-emptive or bid to make.

Steve,

 

I thought a constructive raise is weaker then limit, but better then preempt.

like if you play:

1S-3S: 4 card S with nothing: preempt

1S-3C: 4 card S with 7-9 HCP: constructive

[Gerben42]

Mixed Raise

 

2♠-x-4♠ to play may be pre-emptive or bid to make.

 

No that is not a mixed raise. A mixed raise is a limit raise based on distribution, example:

 

(1♦) 1♠ (p) 3♦

 

A constructive raise would also be

 

1♥ p 2♥

 

1♥ p 2NT would be a "forcing raise"...

[ralph23]

Hmmm.... yes there's some confusion on the terminology. Gerben has it right, although I think some people play a "mixed raise" a little bit lighter on HCP than the 10-11 typically thought of as a "limit raise"-- just for clarification not correction..... that is how a lot of people play the jump cue bid, however.

 

Bridge World glossary will fix you up.

 

Without competition:

 

♠: 1♠ - 3♠, typically showing 4 pieces and good-10-to-11 points. It is not forcing.

 

My understanding is that "limit raises" are newer (e.g. 40 years old only!) in the US than in Europe but that's just from reading it somewhere. I've never played in Europe. In the "old style" in the US (from the same days where everyone played strong and natural 2-level opening bids), this start (1♠-3♠) was game forcing. Now many Americans use.....

 

Jacoby 2nt: 1♠-2nt. Artificial and GF, so as to enable use of the "limit raise" style described above.

 

A constructive raise is 1♥-2♥, where 2♥ is the same as in standard, except it's not real crap; it's constructive, not just a "courtesy" raise with 5-6 (or maybe 7). This isn't technically a "convention" but rather a "treatment" of major suit single raises.

 

There are also "inverted minor suit raises" (see Bridge World glossary) but these aren't called "constructive" in the ordinary parlance, although they are certainly more constructive than "regular" 1♣-2♣ raises! But inverted minor raises are unlimited and can have extremely high point count, limited only by the fact that partner opened.

 

If you play 1nt forcing in response to partner's major suit opener (as you will if you play 2/1), then you have some other little diddies to use:

 

1♠-1nt

2♣-2♠

 

Just a preference for ♠ obviously, and to boot partner may have a "bad" hand with 3♠ and 5-6 points (or maybe even 7), when playing constructive raises. Or he may have a reallly bad hand 3 points with 3♠, trying to keep the opps out of it by conjuring up a 1nt bid with ♠.

 

I don't play constructive raises, but I believe that, if you do, you must play 1nt forcing, n'est ce pas?

 

People also play Bergen Raises, an artificial jump shift in a minor to show a limit raise. This frees up the 1♠-3♠ sequence to be preemptive with 4+ trumps!

 

1♠-3♣. 6-9 HCP (more or less) with 4+ ♠ support.

1♠-3♦. The same as "limit raise" defined above.

1♠-3♠. Preemptive.

 

Reverse Bergen - reverse the meanings of the minor suit responses.

 

In competition:

 

Cue bid raises. I just made this term up. Not sure that it has a real name...Some say CARLOS (Cuebids Are Raises, Limit Or Stronger) as an acronym. 1♠-(2♣)-3♣ = limit or better raise of partner's ♠.

I would argue for a more "generic" definition:

 

Limit Raise = A bid that shows support for opener's suit with enough strength for game if opener is at the upper end of a minimum opening bid (about 11 support points). This definition encompasses bids other than a jump raise, like the direct q-bid showing a limit raise or better, etc.

 

Constructive Raise = A raise based on honor values that convey a specific range of hand strength with the intent of making the contract and enabling partner to judge game possibilities.

 

Constructive Major Raise = a specific convention whereby a 2M raise shows 3-card support and about 8-9 HCP.

8-9? More like 8 to bad 11.

[jtfanclub]

The way I think of it is...

 

Imagine a minimal opening in the system in question. For SAYC, that would be 12-14 balanced.

 

A Pre-Emptive raise is one where you don't expect to make across a minimal opening.

A Constructive raise is one where you do expect to make the contract, but not make game, across a minimal opening.

A Limit raise is one where you expect to make the contract, and can also make across a minimal opening if it's on the strong end for a minimal opening.

A Forcing raise is, well, forcing.

 

Across SAYC, then,

Pre-emptive would be 0-7 hcp or so

Constructive would be 8-10

Limit would be 10-12

Forcing would be 13+

 

But in fact HCP doesn't tell the whole story since there's the amount of support, shortness, etc. etc.

 

It also doesn't color for flavor. If you tend to open balanced 10 counts with a 5 card major, then your responses should have to be a little stronger to fit. If you play a 1NT as 12-14 and you frequently open it with a 5 card major, well, now your responses can be a little weaker. But that's the basic idea.

 

A regular raise includes the high end of Pre-emptive and the Constructive hands...you don't expect game across a minimal hand, and who knows if you'll make 2?
