If the opps haven't looked up/discussed defenses to NT overcalls, that's not my responsibility unless it's made to be by the regulating authority (for example, certain ACBL midchart conventions). Why should I have to tell them a defense to all natural bidding over their NT, for example?
I never said users have to hand out defenses. Especially to common conventions. But if you are using something not well known or not reasonably expected to be well known (and "natural" certainly should be), you have an ethical obligation to make sure there is a good defense available.
The average player does not know Raptor or Suction or ... vs NT. Unfamiliarity should not be the reason those conventions score well. Using them more skillfully than the opponents use the reasonable defenses to them should be.
