As it happens, due to the opps using, badly, a bad method, double might have hit a home run. I'm assuming that opener would bid 3H and that west's double would not be responsive
This is an interesting question! We play 1H, Dbl, 2H, Dbl, and 1H, Dbl, 3H, Dbl, as responsive because opponents have found a fit and we don't look for low level penalty doubles when opps have a fit. An auction such as 1H, Pass, 1NT, Dbl, 2H, Dbl would be penalties as there is no indiction that opps have a fit.
But I have never considered 2H, Pass, 2NT, Dbl, 3H, Dbl where there may be a fit I think it should be penalty, but will ask partner next time we meet up!
