Standard treatment for responder in an uncompetitive auction is to respond in majors up-the-line after 1m-p-? Regardless of strength or suit quality.
Conversely, if partner has doubled a minor (1m-X-p-?) it is more common to respond in spades, to be able to bid hearts competitively and comfortably at next turn. For reference check my problem from last October 8, with ♠J1063 ♥J1096 ♦A96 ♣83 where the votes for 1S outnumbered 1H by 66:20!
One of my partners asked me what is best when partner has opened 1m and your RHO has doubled, creating a competitive auction. I thought this an excellent question. Surely the "reflex" action and likely standard is to "bid through the double" and just respond 1H, but I try to think outside the box and not take reflexive dogma for granted. Surely bidding spades first then potentially hearts later sounds like 5-4, but missing a spade fit if they bid actively might be a big price to pay. If you are willing to bid 1S with 4-4 in response to partners double, perhaps also for 1S over RHOs double.
In the following poll please assume Standard American (or maybe include Precision over 1D) and you are holding a modest but not worthless hand.
