Hello. In my last blog I talked about white's sharpest variation C3) 8.Bg5. But the most popular variation is C4) 8.0-0. White simply castles before reacting in the center.
Now white has two options.
In my next blog, I'll look at white's "doomsday" variation in the Sozin Attack. In other words, it's the most popular and considered the most dangerous.
