Yeah, I forgot about the issue of partner's inexperience, and fixated on the potential UI issue.
Although an inexperienced player might just not be sure if splinter is alertable or not, so the UI doesn't necessarily suggest a misunderstanding. You might not be in real trouble unless an opponent asks about the 3♥ bid during the auction.
I think but my memory is a bit hazy now.
There was no alert.
We use written bidding so the player leaned forward to make an alert then stopped.
There was then a question.
The answer initially indicated it might be a splinter then she changed her mind.
Eventually she said natural or the equivalent and did not alert.
The opponent passed and there was more thought and eventually a 6
♠ bid.
Just to be clear I meant the subtlety of expecting a bid of 7
♥ to guarantee both minor aces.
