1C was polish club although I think it doesn't matter here too much. Partner is 12-14 balanced or 4-4-1-4.
3C was mixed raise.
Our double was negative 4-5 hearts, if 5 hearts then 7-11 (stronger hands or hands with 6+hearts bid 2D as transfer instead of double).
Should we double now ? If not how close we are ? If yes how obvious is that ?

(For the record I passed and we missed laydown game)
