The Cozio is pretty solid. My one comment is that on move 6, is d6 possible? It seems strange to surrender some central control. After d6, the critical line seems d5 a6 Ba4 b5 Bc2 Na5, when black can transfer the knight bia b7 to c5. c7-c5 or c7-c6 seems possible to to attack the center, but that seems more risky. I think its playable, but I do not know the theory or anything.
Cozio Defense
Sort:
Lately I've been experimenting with the Cozio Defense against Ruy Lopez. I'm batting about 50/50. I have found that it takes patience to defend against Ruy Lopez, and playing the Cozio is no different. It kinda forces white to modify his strategy somewhat, which is why it surprises a lot of strong players. Check out this match, and give me your thoughts. Also, I would appreciate if someone could point me to some resources on how to play AGAINST the Ruy Lopez. Enjoy!
