Just trying to measure what people open these days in a strong club base.

What position, Adam, and what vulnerability, and under English Bridge Union or American Contract Bridge League regulation? (Apologies for being pedantic but there are some hands I would, and some I wouldn't, and I am sure that are some that will result in the director being called.)

Let's say first seat, none vul.

Thanks. I've used a criteria of 10-15 HCP. All hands are 5-4-3-1 so as long as they have at least 10HCPs I will open. 5-4-2-2 shapes are more problematic, I feel. Only hands less than 10HCPs where I've opened is AQxxx Kxxx xxx x and KQJxx QJxx xxx x as all the honours are in the long suits and there is an easy rebid.

For me it's important that the lower limit for 1M openings matches the 1N range (as in rule of 19 openings + 14-16 NT IMO) so that Opener can pass 1M-1N on all balanced hands that are too weak for a 1N opening. So even though I'm very comfortable with playing a wide ("10-21") 1M range in my 2/1-like system, and the strong club opening allows me to use a narrower, potentially easier-to-handle, "9-15" range, I wouldn't be able to handle that range the same way without changing the 1N range first. So default for me is to play rule of 19 1M openings + 14-16 NT, the same as in my 2/1-like system.

Btw,

KQJxx
KJxx
xxx
x

contains only about 9 hcp the way I count (using tenths), and so doesn't meet the (or my) rule of 19.

It is easy really, Hcp and shape is everything, so first 3 ok, perhaps telephone numbers in major would want to make one undervalue the hand a bit.

1♦ min is just to get into the bidding early anyway

I was tempted to do a Kaplan and Rubens evaluation on all the hands (for what it's worth) but declined, as I followed the general rule that honours in long suits, and honours stacked together usually increase a hand's K&R value.

But obviously, there's the semi-pre-emptive value of opening lesser hands with 1♠ in first seat, non-vulnerable, that has to be taken into the equation too.

An interesting poll so far.

[Zelandakh]

I thought I opened light but I can see from the poll that I was mistaken. The 5th hand is the borderline for me; I can certainly imagine not opening it vulnerable if I was in a less aggressive mood on the day. Everything below that is a clear pass for me and everything above a clear 1♠ opening.

[nullve]

I would open the remaining hands with a canape preempt* (2♥) in my 2/1-like system.

* It's perhaps not worth noticing that

my canapé preempts = cr-ee-eam my p-p-pants.

If I have a reasonable expectation of taking 4 tricks with my suit as trumps, and adhere to any silly HCP rules by governing bodies, then I like to bid...as that is the minimum my partner should be working with, 4 playing tricks. (It is my current temperament to round up, 3.5 playing tricks tend to get rounded up to 4.) Edit: I should add that I do expect 1M openers to have at least 1.5 defensive tricks as well.

[hrothgar]

I found hands 6 and 7 the most interesting.

For the most part, it felt as if hand strength was decreasing monotonically, however, I passed #6 and would open with #7

[awm]

FWIW the high card point total was decreasing monotonically. Within a HCP value I ordered the hands best to worse. It is probably the case that some 10HCP hands are worse than some 9HCP hands (or similar with any two nearby point totals) but I didn't make that judgment in my ordering.
