For what it's worth, I see this all the time. Harrington meantions bluffing with suited connectors from EP in HoH1, and he mentions he does it something like 15% of the time.

People read his book, then try this play maybe 50% of the time and feel terribly sophisticated when they do it.

Remember, this type of move is marginally useful and only when you can depend on the fact that your opponents are observant.
