I put these guidelines up (written by me..so anyone is welcome to pick them to bits) for some friends of mine who have been going for traffic lights scores with bad preempts. I have seen a number of preempts that have gone for traffic lights recently...when no consideration of vulnerability or seat position or suit quality is taken into acount.
 
Here are some things to take into account.
 
 
1. Length of trump suit.
 
For 2 level preempts of weak jump shifts / overcalls 6 trumps
For 3 level preempts of weak jump shifts / overcalls 7 trumps (occassionally a very good 6)
For 4 level preempts 8 trumps or a good 7
 
Comment : Stick to the law most of the time. Do not preempt at the 3 level with crap 6 card suits when the 2 level is available. On the other hand with a reasonable hand and a good 7 card minor and the right vulnerablity you might choose 4 minor to maximise the difficulty for the opps (in preempts taking these factors into account is everything...making undisciplined preempts just because you have 6 cards in a suit will often result in really big minuses and destroy partnership morale). And with 7 trumps go to the 3 level (not 2)... I don't know how many times I've thought my hand isnt fantastic and bid at the 2 level when the 3 level preempt will be raised by partner and makes game in a major. (The same length criteria apply to weak jump overcalls and weak jump shifts)
 
2. For preempts suit quality is everything.
 
Read this line 100 times. If you want to preempt with crap suits...you'll go off in a lot of no trump contracts when your partner has a good hand...and you'll go for traffic light penalty scores.... .
 
So for weak 2's I prefer 2 of top 3 or KJ10 or QJ10.
For 3 level preempts in 1 2 seat I prefer KJ10 at worst...the reason is often you will have preempted your partner and holding HX in yr suit they will be expecting 7 tricks in NT.
 
3. Rule of 2 and 3 
 
These aren't used so much anymore but basically when vulnerable your hand should be able to make 2 less than the bid and when non-vulnerable 3 less.
 
4. Seat position
 
Seat 2 has the greatest chance of preempting partner and carries the greatest risk of going for a big penalty.
Seat 1 carries less risk than seat
Seat 3 is preemptors heaven...
 
5. Vulnerability
 
Vulnerable / nonvulnerable - be very disciplined
Same vulnerabilty - be disciplined
Nonvulnerable / vulnerable - can be less discplined
 
6. Form of scoring.
 
I tend to prefer preempts in MPs 
 
7. Set some firm guidelines with your partner
 
One advantage a regular partnership has is determining some firm guidelines. If one partner likes getting in with undiscplined preempts (one of my earliest partners loved them..so we came to an agreement that in MPs only when nonvul/vul they could have their head so to speak..)
 
So as an example of the sort of agreement you might have in terms of discipline...
 
 

You vulnerable,
opps not   

 Same
vulnerability 
 You nonvul,
 opps vul
 1st seat  Very  Very  Some license to have
less than expected

 2nd seat
 

 Very

 Very

 Mostly disciplined

 3rd seat

 Mostly disciplined   Anything goes  Anything goes
 
And finally...preempts are good...and very common in more competitive bridge...this is not an argument against preempting...but an argument for a little sanity in the choices.

Thanks - very useful guidelines indeed.  I think if anything I have been too conservative on my preempting.  I assume you subscribe to the view that preempts are out with a four card (other) major in seats one and two.  What about other suits and voids in the other seats?
 
Once again thanks
 
Cheers

1. Having a 4 card major or a 3 card single raise
 
Im not that fussed - it depends on the hand.
 
If the major is spots like 7654 and I have a suit like KQJ10xxx then I may choose to preempt.
But if I have a hand like KJx xxx QJ10xxxx - (a good spade raise and an ok heart raise) I am not preempting.
 
2. In 3-level preempts and above I may sometimes have a void...
 
3. For weak 2's there is usually no outside 5 card suit and no voids.
