Maybe the few long games i have played this weekend did me good.
I went back to the Caro Kann opening, long games, give time to think about them. I hadn't used the Caro Kann for a while, and i noticed its can be a strong starter for black. What it isn't real Carro Kann, its a modern defense i play, based on Carro Kann, perhaps its something new. Anyway it raised my blitz rating again, and it was even quite relaxed to play this. I had lots of time left, it was a quick game, also for my opponent..
