A responsive double is an artificial double when LHO opened the bidding, partner overcalled at or below 3♠, and RHO raised. The last doubles in the following sequences are responsive doubles. A responsive double shows a hand with length in all unbid suits (similar to a takeout double) but not enough strength to make a cue-bid. This is the classic responsive double: It shows a 3-suited hand short in ♥s, but not strong enough to cuebid at 3♥. This is usually a responsive double; It shows a 2-suited hand with both minors, but not strong enough to bid 3♥.
