A negative double, for take-out, is the responder’s double, ie opener’s partner
The higher a negative double forces the bidding up, the stronger the doubler must be; each level higher requires the equivalent of a king more (ie 3 points)
Remember there is an option of passing rather than doubling (you don’t HAVE to make a negative double at all; with no points, for example)
A negative double denies a fit for partner because showing the fit is first priority in competitive auctions
A negative double denies a stopper for no trumps
A negative double shows a hand that’s hard to describe (not enough points to show the suit, or two suits)
If responder passes, opener should try to reopen with double, because responder may have a lot of the opponents’ trumps
1♣️ (they overcall 1♦️) X (double) = precisely four hearts and four spades
1♣️ (they overcall 1♦️) 1♥️/♠️ = four + hearts /spades
1♣️ (they overcall 1♥️) X (double) = four spades
1♣️ (they overcall 1♥️) 1♠️ = five + spades
1♣️ (they overcall 1♠️) X (double) four + hearts (not enough hearts, or points, to bid 2♥️ forcing)
