The original reasons were that responder lacked either or both of the strength and length for a natural forcing new suit bid
This 1D (1S) x.
Fairly early in the history of negative doubles this became a way of showing hearts. It showed either 4 or 4+.
If responder held 5+ then he lacked the values for a 2H bid
You do NOT bid 2H in that sequence when you have 5+ hearts and whatever your system strength requirements are for a 2 H bid
1D (2C) x. Some might think this shows both majors but that’s not mainstream expert treatment. X shows either both majors or 1 major and good diamond support. Limiting it to both majors causes serious problems. Say you hold AQxx xx AJxxx xx. If x promises hearts as well as spades you can’t double and the spade suit may be lost
But if you held AQxxx xx AJxx xx, you’d bid spades since you have 5+ and the strength to bid.
All of that is by way of saying that negative doubles DENY a 5+ suit with whatever you require for a free bid. Btw that’s why negative free bids fell out of fashion….they inverted the problem…one has to double with a good hand and a good suit and preemption really screws things up
Negative doubles fix a problem. Good hands with good suits aren’t part of that problem and DO NOT use negative doubles
Good hands with suits too short to bid or weaker hands with long suits but not the strength to bid….those are the problems
With a slam oriented 6-6 major hand, you by definition have both the length and the strength to bid your suits
I suggest finding a reasonably good basic 2/1 text because you seem unfamiliar with basic bidding ideas. You’re far from alone in that, even amongst players who’ve been playing for years
Most people ‘learn’ from other club level players, virtually none of whom have a good understanding of basic principles. So we have the uninformed learning from the uninformed. As one of the local experts I admit to some fault here. But I’ve tried teaching at the club and in my experience people may listen, may nod their heads, but they either forget or choose to revert to what they’re used to since pretty much given up teaching
Thanks for the clarification.
I have seen it played as, and played it, as negative or slammish hand.
