An old chestnut

It's been a long time since anyone has blundered into this trap against me. It's one of the oldest known opening traps. This entire game was first noted (and perhaps played) by Greco in 1619. Note that 6...Bg7!, as in Lombardy-Regan, New York 1974, is a big improvement over 6...Nf6?? Unfortunately for Black, as I've previously written, that line is busted too. My opponent lost the old-fashioned way, 1619 style.
