Caro-Kan - finding a novel trap!

 I was dabbling this evening, and discovered a nice trap in the Caro-Kan.  Admittedly I wasn't looking for it, but if you don't try interesting ideas then you won't make your opponent trip up! Part of the fun of chess is actually the voyage of discovery.  The placement of each piece had a profound impact on the games verdict.  I thought I might be able to win my opponents Queen, but instead I went for a win of the oppoent's light squared Bishop, then realised that their dark squared bishop was also en-prise.
