I'm no expert on the use of screens, and I don't wish to enter this long (and rather silly, imo) debate on the meaning of "intently", but it seems to me that the one of the purposes of the screen is to prevent you from seeing the mannerisms of either player on the other side. I would not look favorably on a player who attempted to circumvent that purpose, whatever "intently" means.
Oh, it is never silly to attempt to work out what the words in the Laws mean. It may be fruitless, because once you have worked them out there is a tendency for people to say "that is all very well, but it is obvious that when we used a word with meaning X we actually intended meaning Y".
But in this case there isn't really a problem - "intently" is the adverb from "intent", and "intent" as an adjective means [per the OED] "having the mind strenuously bent upon something; earnestly attentive, sedulously occupied, eager, assiduous; bent, resolved." Confusion with the notion of "purpose" (per "intentional" as opposed to "accidental") is just that - confusion.
The Laws prohibit you from looking at an opponent "with your mind strenuously bent upon something" - in this case, discovering something about his cards that may assist you in the play. It does not matter for how long you look, nor for how long your mind is bent (yes, I know, but spare me the jokes). You may not do it at all, let alone peer under a screen to do it.
