Kaplan Inversion not GCC?

[zenko]

I just noticed Kaplan Inversion is removed from GCC. Is that a typo? If not, I would really like to know whose brilliant idea was that, and how did that came about? Even more, I can not find any evidence that KI is even Mid-Chart allowed anymore, I checked "Additional Mid-Chart approved bids, defenses and segment approvals can be found at http://www.acbl.org/play/defenseDataBase.html" and i can not find it there.

 

I get it that KI in its core really is a "tell me more bid that does not promise GF values", which seems to be disallowed even on Mid-Chart, but c'mon, 1S is really just like 1H-1NT(F1) when playing Flannery, how hard is for opponents to deal with that? What's next to go, 1430 maybe?

It is allowed by 3 in the midchart. Thus, while it does need to be a midchart event and does need a pre-alert, it doesn't need a defense. This is similar for other constructive bids like transfer responses to "natural" 1♣ openings (I.e., non-precision 1♣ openers that you'd see in SA or 2/1 style).

Thx for clarification, do you maybe also know a) are 3+ cards 1M responses on 1C/D openings allowed, and B) are transfer overcalls allowed?

 

Thx in advance!

When you're asking about transfer overcalls, are you referring to

 

1. Transfer advances of overcalls

2. Actual transfer overcalls (Hypothetically, one might play a system in which a 1♥ overcall of a 1♣ opening would show Spades)

 

On the 3+ card 1M responses:

 

A 1♥/1♠ responses that systemically shows 3+ cards isn't considered a natural bid; therefore this needs explicit sanction. I don't recall any section of the GCC that explictly allows this bid. I don't think that you can play this in GCC events.

 

With this said and done: I do believe that you would be allowed to play a method in which 1♥/1♠ promises 4+ cards but on rare occasions, you chose to deviate from you agreements and bid 1M on a three bagger. (You are allowed to exercise judgement). Obviously, the question of what constitutes "rare occasions" is a very tricky. I don't pretend to be able to offer any good guidance here. I will suggest that if you have a systemic way to check back and ask whether responder has a three card suit you've crossed well over the line and are somewhere in the middle of the next county.

Yes I was asking about transfer overcalls, I can not find any mention of them being allowed, so I assume they are not allowed, but it strikes me as bit strange to allow transfer advances of overcalls, transfers after doubles, but not transfers overcalls too.

 

Regarding 3+ cards responses, the spirit of the rule seems to be exactly like you described, but if you allow canape systems like Blue Club (or what Rubin, Ekeblad and their crew are playing) where 3 card responses are common, there has to be some compromise. Pretending that 3 card response is not systemic, just because you usually have 4+ might be convenient but is completely dishonest.

I agree with you in principle.

 

In practice, I think that the regulations in the US are hazy (at best) and are probably deliberately designed this way.

I played an AWFUL lot of Blue Club back in the day. I don't recall many situations when I felt compelled to bid a 3 card major over a 1♦ opening. There are all sorts of situations where one bids a three card minor over a 1M opening - sometimes even a two card card minor - however; there really isn't much need to fake a major.

 

Not sure what Becker and Rubin are up to, but I suspect that it deviates significantly from Blue Club...
