My partner doubled with the hand shown. Certainly, a 3♠ would have been correct since we do want to bid game with a min of 15 opposite 13 in HCP.
My question is what in the world was she thinking? Is there something going on out there that I don't know about that may have misled the poor dear? My impression has been that the 'modern' treatment is that a double in that position shows 'cards' with three pieces or better in spades, all based on the LOTT. Is this actually the case? Does anybody who can play play that double as reopening showing short spades? (Note the rare use of "play play" in the last sentence.)
