Again both of these examples hands are really close but I would have passed that 54 9 hcp hand.

Ok, so you do not open
AQxxx.x.Kxxx.xxx

Would you open
AQJxx.x.Kxxx.xxx
or
AQxxx.x.KJxx.xxx
or
AQTxx.x.KTxx.xxx

Where's your "floor" for 5431's? and why is your "floor" where it is?

Open nearly all 5431 10 point hands that are not flawed. Basically the biggest flaw is holding short suit honors, don't count them for much. Another flaw would be poor suit quality in your long suits, especially the 5 bagger.

pass AJ9x...9xxxx..x...AJ9
pass Kxx...x...KT9x...ATxxx Prime high cards but spread out and awkward rebid problems but add a jack or switch minors and I open.

A nine pointer 5431 would be borderline if you give me a bunch of honors and spots in my long suits

I think there are four good reasons for making changes:

i) You are a top class full-time pro partnership and the edge you have from playing the best (rather than a 95% solution) is worth working at. 

ii) You are a long-term partnership, but when you first started playing you didn't work a lot of things out in detail. (For example, I used only to play with one partner in 'fun' events; we played very little system. We've recently started playing more seriously, so we've improved some of the stuff that we were only really playing by default because we hadn't got round to discussing anything more complex.)

iii) You are a new(ish) partnership and don't yet know what you want to play, or are working on one particular area. We went through a phase of fiddling with our 1NT response structure over the course of a few months until we were happy with the final result, for example.

iv) You become convinced over the course of a large number of hands that what you are currently playing is definitely a long way short of 'best', and the pain of change is outweighed by the benefits.  This is the same reason as when people change their methods after one bad result, but I think you need to apply a more long-term approach: only when you have a string of bad results and few good ones is it worth changing.

Before the age of Internet bridge,as a non-professional player,I had not enough informations about new/fresh conventions and systems.
Thanks for USA's computer technology,I can take part in these forums and other online bridge activities.
After read lots of bidding files,there is a problem up to me,which is that whats the principle of bridge bidding?

You know,in the bridge match,there are lots of different systems playing a same set of cards,most of them can arrive same contracts,that's to see,there are a principle of bidding.
So,trying to find the principles,I decide to reaearch on bidding,conventions and systems,and now I think I might get some of them.
That's the reason why I have a special interest on system changes.

Thank you for accessing my blog and giving some opinions on systems or conventions.
