Just For Fun, Part 2

Sometimes you read about a neat trap in a book and you try to play it, but no one ever plays the right moves.  Either they know about it and avoid it, or they don't know about it and accidentally avoid it.  But sometimes they fall right into it.  And sometimes the trap has a bad line and a very bad line.  This is an example of the very bad line.

If White could have read my mind, he would have said "Will you stop saying 'Please play 13. Nf3'?"  I'm not a big fan of opening traps, but I do like ones that come out of natural positions and are well hidden.  And ones that my opponent falls for are the best of all.
