Another situation. You can play "without danger" that a strong 2♣ opener can be a weak hand with long ♦. No problem at all. BUT TELL YOUR OPPONENTS!
Perhaps this is the reason ACBL prohibits psyching strong artificial openings.
Perhaps, but in that case it is for the wrong reason.
If you play the version of Pubbet Stayman popular in the NL, where a 3NT response to 2NT shows 5s4h, it is similarely risk free to open 2NT on a weak 5h5c in third seat nonvulnerable.
If you have an agreement that allows you to make risk-free psyches, and you actually make those risk-free psyches, the psyche must be treated as an agreement and must be disclosed as such (and must conform to whatever HUM/BSC regulations are in force). Whether the psyche itself is an artificial bid is not the issue, IMHO.
