Sicilian Defence, Alapin Variation

That in itself is very simple.

You don't have to go into a lot of theory, as long as you explain the main ideas.

Against the Sicilian, I had the Alapine.

Now, the Alapine, you could make a huge course on it, or you could make it very simple, if you pick the right lines.

Also, I also recommend a lot the Vienna.

I don't think we have any course in chess about the Vienna with the G3 line.
