In line with my latest prior post, what should a "Super-Accept" look like?
You open 1NT with 15-17 HCP (occasional upgrades), and partner transfers. What is your "range?"
I showed how the "normal" range would be 2-6 cover cards as far as strength, with 2-5 cards in support of the major. Suppose that we took the cover card range and added to it the variance off of an expected simple 3-card fit. For example:
3 cover cards. 3-card fit (0 variance). 3+0=3. Net of 3 Super-Accept Credits (SAC's).
4 cover cards. 4-card fit (+1 variance). 4+1=5. Net of 5 SAC's.
2 cover cards. 5-card fit (+2 variance). 2+2=4. Net of 4 SAC's.
4 cover cards. 2-card "fit" (-1 variance). 4-1=3. Net of 3 SAC's.
If we do this, then perhaps the worst SAC count is 1 SAC (2 covers, no fit), while the greatest is probably only 7 SAC (4-card fit plus 6 covers or 5-card fit nut then only 6 covers), because a 5-card suit with six covers would have upgraded to open the major and jump rebid 2NT. Thus, the SAC range is 1-7.
With 7 SAC, force game. With 6 SAC or 5 SAC with something else, show a strong super-accept. With 5 SAC without something extra or 4 SAC with something extra, show a medium super-accept. With less, do not super-accept unless you have 4+ support and a means to show a weak super-accept.
Notice how a 3-card super-accept is possible in this approach.
