Example 1:
Example 2 (in a context where cheapest minor is 2nd neg):
(1) First and foremost, do we agree that 4C in each auction above is a cuebid?
(2) On auction 1, suppose responder holds AQ9xxx / -- / xx / AKxxx or AQ9xxx / -- / x / AKJxxx.
Is the normal thing to do just bid a forcing 3S?
(2a) opener's followups to 3S I assume are cuebids, so can I bid 5C/6C naturally after opener re-rebids 4H?
(2b) Are there even any/many hands where opener would rebid 4H and not 3N?
(3) On auction 2, typically the agreement is that bypassing 2D shows a good suit (meaning that it meets some honor requirements, maybe 2 of 3).
So responder, holding like x/QJx/xx/A10xxxxx can't bid 3C over 2C (honors), 3C over 2S (dbl neg), can't bid 4C over 3H (Q). Of course, it's not crazy that 6C is the right spot here. So what gives?
(4) Do you have any meta-rules that cover when a new suit is a cuebid setting trump and when the new suit is natural? AORN, the best I've got is "Don't look for a fit at the 4-level when partner is odds-on to be short in that suit." Basically it's "it's a cue when it's obviously a cue." Until it's not, of course...
Any help appreciated as always.
