Our convention card* says the point range is 5-9ish (with caveat that with extra shape we may have fewer values).
Fourth board of our evening....
I was expecting partner to have a tad more for his bid when I plonked 6♥ on the table (which made on a misdefense).
By the end of the evening (rather than the end of the hand) our oppo described my partner's opening bid as a psyche....
I'm not sure if it is or not (and it evidently wasn't fielded given oppo had chance to score a top on this board).
I welcome your views....... (and I think - even before reading comments - that I will tinker with HCP/wording on our convention card).
* PS Convention cards seldom used in local bridge club, but I always have available when playing with regular partners. Last night I think we were the only pair out of 13 to have convention cards available! Not that changes my question or our bidding here.
