Doesn't look like a psyche to me!
A psyche is a deliberate attempt to mislead. My guess is that the person who opened this hand intended to describe the hand rather than mislead - and that is not a psyche.
Of course, as mentioned by other responders, this is a matter of regulation. You may not psyche opening conventional bids in European Bridge League pairs events - but you may in their teams events!
I think the pair just meant it naturally. Sure, it is not 11 HCP, but pairs open 1
very light when they are 6-5 and people are not surprised when that is not 11 HCP. It is just the same for a convention.
