Holding Q10,10983, K965,AQJ

Why would one open 1D and after partner bid 1S rebid 2D?
I apparently do not understand their systems!!!

When I asked they told me that if they would have rebid 1NT it shows 15-17 pt NT
Why didn't they open 1NT 12-15 to begin with??
Can someone explain "modified KS"
Thank you

No clue what they're doing (Doubt that they understand either)

Playing KS, this is either

1. A NT opener
2. A first seat pass

Correct

I would pass in first seat. Kaplan devalues that queen.

In KS you cannot rebid that diamond suit either because 2d shows an unbalanced hand, 5+ diamonds 15+ or 6+ diamonds 12-15 hcp.

KS is a sound opening system for minor suits, you open sound, but you respond agressive.
The player who you played with does not understand that.

Which was intended?
We play 'modified KS'. OR 'WE' have modified KS.
One is well defined as what is a 2D rebid.
Second is "as we please" 2D rebid.
Feels like a "black magic" rebid, doesn't it?

Been there often -- what can be done?

Actually, I play modified KS, and a few other st BBO, we actually have a 34 page system notebook.

A system does not mean the players are disciplined, I do not partner all from the KS group i am acquainted with mainly for their failure to bid according to the system`s discipline (ie, I do not like the dummies they bequeath me or their cuebids making my declarer play that much more difficult.)

The reason it is called Modified KS is because transfers, bergen raises and transfer prempts are included, which were not included in the original KS system. When playing GCC we abandon the transfer prempts leaving only namyats.

What seems to have happened is that your opps misbid, but dont blame kaplan sheinwold for it and the director cannot penalise bad bidders lest he be left with less than one table per tourney.

Also KS IS NOT AND UNNATURAL SYSTEM. In fact it is not much different from 2 over 1 with a weak nt 12-14.

Any five-card major system involves some fundamental artificiality.

The TD can penalise them for it if they have a CPU and do not disclose it. Given that you seem to be saying that these anomalies are common from certain players then a CPU is not beyond the bounds of imagination.

There isn't any rule against being absolutely clueless... This is a clear 1NT opener in KS.

In KS by the book (see the KS Updated notes at
http://www.bridgewor.../ksupdated.html)
opener cannot have 15+ to rebid 2D after 1D-1M. 2D has a narrow range, much narrower than STD. Kaplan defines it as "Severely limited; 12 to 14 and not 14 if good 6-card suit." (See section B-10.) With 15+ opener bids in a new suit unless strong enough for a GF 3D rebid. 1D-1M-2C is treated like a reverse. (So KS players will rebid 2D with hands that STD players would rebid 2C with.)

It's different from STD -- very different in parts -- but it all hangs together way better than most other systems.
