A gentleman merely opens doors - those apparent, and those not so apparent, neatly found out of even the most puzzling situations.
A gentleman does not break down impassable walls to get what he wants. No no...he makes his peace with it. Pivots, and begins again.

He can't do it again.
The rule numbered first of all, indexed at an empty zero: you cannot break the rules.
And you can never ignore the secret clues.
