IMP, best hand South, robodupe, pro GIB 32
Perhaps I should have paid more attention to the vulnerability and less attention to the published description of 3D.
I find it quite frequent that a jump overcall is described as "aggressive weak ..." only then to turn up with a borderline opener.
My interpretation of "aggressive weak" is just another way of saying "weak weak". If they really mean to describe it as "wide range" then that I think is the terminology that should be used. Just removing "aggressive" without replacement would be an improvement.
I suppose that an upper limit of 11 HCP is inconsistent with "weak weak", so maybe I only have self to blame.
Come to think of it, I can't recall the last time that it made a "weak weak" jump overcall at my table, although that could just be a combination of dealing stats and my poor memory.
Would I have tried 3N opposite a jump overcall described as "sound weak ..."? I can't say now. I still would not be expecting the Diamonds to be running without loss, the hand is a misfit, and for all that my Hearts are well placed and bolstered we are a bit short on total strength. Perhaps solid suits are just hard to bid in competition.
