I don't know much about "hand history" questions, but if what you are saying is true (I'm not saying it is or it isn't), therein lies a problem. You should not accept highly-subjective, easy-to-ask, easy-to-answer questions. They should not be part of this site.
Telling yourself that a type of question is okay as long as it doesn't get asked too much runs afoul of how Stack Exchange is designed.
Consider why you are going to hate answering these questions over and over — They become repetitive and formulaic. The solution is to create a canonical answer that describe how you are answering these question and close these highly localized questions as a duplicate.
This is a microcosm of why we discourage questions asking for "lists of ideas" or "list of shopping recommendations." There's nothing inherently wrong with asking "What do you think about…?" but in this type of merit-based Q&A site, these types of questions tend to become the low-hanging fruit that lowers the bar of entry to asking useful questions. Everyone has a story they would like to share, and there's no end of random opinion people are willing to pitch into the conversation. What gets lost is any appeal to expertise.
Subjective questions that anyone can answer with random opinion encourages a free-for-all glut that will thwart any appeal of expertise on the site. A stream of questions asking over and over, "What do you guys think? … What do you guys think? … What do you guys think?" will just as quickly fill with endless opinions. To me, that's not building a cannon of knowledge. It's a discussion board… and that's not what we do here.
