Basic Precision: Jump shifts
#1

When Precision was invented, everyone played strong jump shifts (allthough most Precision authors played non-forcing jump shifts after a 1♣ opening). Nowadays all kinds of natural and artificial jumps shifts are fasionable.

My vote would be as follows -
If 2/1 is GF: 3♣ = natural, pre-emptive
If 2/1 is GF except rebid: 3♣ = fit jump with 3-card support
If 2/1 is SAYC-style: 3♣ = some sort of 4-card raise
If 2/1 does not promise a rebid: 3♣ = natural, strong

because this is a "BASIC PRECISION" thread Maybe david didn't realise where BASIC Precision systems differ from "sayc" or "2/1" or even "Acol" ( and other systems I don't list here because I don't know what they are called) as in Precision the 1♦♥♠ openers are LIMITED to 15 pionts
In ANY version of Precision I have EVER played in 35 (yes thirty five years of playing different Precision systems I have NEVER played 2/1 as game force cos system does NOT need it



Even over a Precision 1♣ a JS to 2 level is NOT a game force !!

Hmm. Despite what you say, all four of the options I described above have had some support in the poll "(non)forcing after a 2/1". I did not intend the statement "if 2/1 is GF then 3♣ should be natural and pre-emptive" to imply that I think 2/1GF is sensible in Precision.

Sorry Micky - you are quite right. I need to realize where the first point is to be blind.
I delete my post now as it is obsolete.

What I find interesting is how few people play/ recall that Precision initially (if not still does) used a 2NT response to 1D& 1M as showing 16+, not Jacoby or various off-shoots where 2NT shows limit raise or better. It also played 1M - 3NT as forcing raise in M, seemingly adapted from some earlier systems like K-S.
If you really want to have fun, take a poll r.e. what an opening 3C bid shows. (hint-hint: It ain't your normal pre-empt per se.)

I doubt, however, that this could be set and expected as "Standard" Precision structure...

I like strong JS in a major, but for strong natural JS in a minor the frequency/gain does not seem to be a winner.

You don't need SJS in a limited opening system (well not in any system but especially not in a limited opening system)
