Is there a fairly standard meaning for double by E in this situation? If relevant, we play the double by W as: 3-suited takeout OR non-GF 2-suited in ♥/♦ (i.e. ELC) OR very strong.
Would it change if the opponents were bidding ♥ instead?
I thought initially that it should be responsive, as in the case where the bidding is (1♠)-X-(2♠)-X, but after reading more it seems that some people play it as values or penalty.
Plus... it's free!
