A trap in Philidor's defense

On move 11, white offers a pawn by playing Nd5. If black chooses to capture the undefended pawn on e4 instead of capturing the knight, Bc6 is going to start an attack that is incredibly fun to play and guaranteed to win even with sloppy play. (Like in this game)

Unfortunately, most qualified chess players will not make such a meaningless move for blacks as 6. ... a6(?), therefore your find does not have a practical meaning.

12. Bc6 would certainly be surprising.
