Is there a good source for learning what expert standard is for various preempts at various vulnerabilities? both before and after an opponent has opened the bidding?

I know there are lots of styles of preempts but I'd like to know the low and high end that a field of experts would consider. Ideally, I'm going to get example hands (of minimums particularly)
and incorporate them in our notes.

I think you'd have to look at records of actual bidding.

You might look at BW magazine and BWS, also take a look at the world championship books and of course vugraph matches.

Probably good advice thus far. What experts may recommend they may not follow in practice. Still, any experts want to take a shot and suggesting absolute minimums for 1st seat weak 2H bids at favorable, white, and vulnerable?

I am not an expert but this is what we play with good success at Match points....Imps is different. We adopt the down 3 if vulnerability is against us, down 4 with equal vulnerability, and down 5 with favorability vulnerability in 1st or 2nd seat. We don't preempt with a 4 card Major in our hand. In 3rd or 4th seat, if partner has passed, we reduce the above numbers by 1.

Partner can do a pretty good job of counting total tricks and make the appropriate sacrifice. When partner has a singleton or void, he lowers the combined tricks by 1.

We do this counting method when we do weak jump overcalls as well

For me, first seat favorable minimums are hands like:

♠xx ♥KQJxx ♦xxxx ♣xx (good five-card suit and out)

♠x ♥KJ9xx ♦QTxxx ♣xx (mediocre five-card suit in a 5/5 hand with a bit on the side)

♠xx ♥QTxxxx ♦Jxxx ♣x (six-card suit to one top honor and some shape, but no other real values)

♠xx ♥J98xxx ♦KJx ♣xx (flattish five-six point hand with a six-card suit headed by the jack)

First seat all white is similar for me, though I'd want one additional spot or a slightly better outside card.

First seat red minimums are like:

♠xx ♥KQJTxx ♥xxx ♣xx (very good six-card suit in a flattish hand)

♠x ♥KJ9xxx ♦xxxx ♣xx (mediocre six-card suit in a 6-4 or more shapely pattern)

♠x ♥Qxxxxxx ♦Kxx ♣xx (bad seven-card suit with a side card)

I wouldn't necessarily say this is "expert standard" or anything; it's just the way I typically bid. Maximum for me is whatever I wouldn't open 1M with; usually with ten-counts and six-card suit I open 2M.

Thanks Adam.

I was watching the Spingold (I think that's the event anyway) on Vugraph last night and 2nd seat at favorable vulnerability there was a 3D preempt on something like Jxxx x KTxxxx xx. I don't know if this is good bridge or not but certainly some people think so. My question is more about whether this 3D preempt is continuous with a 1D opening. I.e. this pair probably doesn't play weak 2 diamond openings (and neither do we) so do folks think that their 3D opening goes anything as bad as this to anything just shy of opening 1D? Or are they likely to pass inbetweener hands and then bid diamonds later? Like pass QJx xx AQxxxx xx? Or is this also a 3D opening?
