I'm not even sure what to call this one. I'm reading Caro-Kann Defense: Advance Variation and Gambit System by Anatoly Karpov.
In the first chapter karpov mentions a move order:
- e4 c6
- d4 d5
So far so good - the gambit system. Then he mentions black has a few continuations. The one that I'm not sure how to put on my board is:
- fe e5
I've never seen the notations de and fe used before. I thought they were for captures but it's very clear karpov is using normal capture notation (with 'x') throughout the book.
How do I understand this notation?
