B15 Caro-Kann Defense
Gurgenidze System

1.d4

[1...e6
was an option, but I had played a French against Lou before (2008 KST) & wanted to complete my book on him.]

2.e4
This lets me write the final chapter but my opponent's usual d4 opening, the Colle, is ineffective versus ...g6 lines.

The Gurgenidze System, a favorite of 12x Kenilworth Chess Club Champion Scott Massey.

5...f6
Black takes the bull by its horns and threatens to win a P with 6...fxe5 7.dxe5 Bxe5. Thus, White has to reinforce the head of his P chain or trade at f6.
