Lots of questions revolving around this hand. The background info: my partner and I play 1C = 16+ or equivalent value (in 4th seat, 18+ if balanced) with positive responses being 8+, though frequently with an A and a K and not ultra flat we'll give a positive response.
1a) Is this a positive or negative response?
1b) Would it change for you based on seat, vulnerability, format of scoring, etc?
2) What sort of criteria do you use when upgrading or downgrading hands that are borderline positive? How do you treat stiff honors? How do you treat distribution as wild as this? 10s and 9s? Aceless hands? Other stuff that fits in this area?
3a) Would it make a difference to you if it was a long major instead of a long minor? With the above hand, if all the suits are interchangeable, are there specific holdings (say, 7321 instead) where you'd be positive versus being negative?
3b) Does it make a difference if, in your system, it's difficult to show a really long minor as responder? (Admittedly, these hands cause problems with the system we play. We don't have this problem with long majors.)
I know it's a lot of questions, but if anyone with a lot of experience in playing big club has any opinions I'd love to hear them. Thanks!
