Whoops, arookalypse

Spotted an oldie but a goodie at the ANU Chess Club last night. I'm surprised it still catches out Caro-Kann players, although this particular variant might be further off the beaten track. Instead of going for the obvious 8. ... g6 to defend f7, Black tried the more aggressive 8. ... Qd5. 9.Bc4 was still the move (as it was against 8. ... g6), when Black is almost forced to play g6 anyway. White still got to capture on f7 after the queens were chopped, and then the calm retreat along the a2-g8 diagonal left the rook in the corner trapped.
