Nothing in life is free. You want garbage on the Sicilian with terrible analysis, sure you can look at garbage youtube videos.
You want legitimate analysis, you've got to pay for it. You can find many sources on the Sicilian at chess4less.com, uscfsales.com, and amazon.com. A lot depends on which Sicilian you are talking. Best Sicilian book I have read was The Sicilian Taimanov: Move by Move.
(Free???? SMH!)
There is a really good course on the Sicilian dragon for free on chessable by GermanMC. Other than that maybe try some short and sweet chessable courses and get the main ideas from there. Other than that, there is also a few free courses on anti Sicilians and Sicilian sidelines which are pretty comprehensive, as well as a completely free video course on the najdorf and many other Sicilians by St Louis Chess Club and Hanging Pawns on YouTube.
Ok, thanks guys
I would like a course or some videos that explains the Sicilian Defense very well with sidelines, how to play against anti-sicilians, and maybe even gambits. I always play this against black and if anyone could recommend me some free resources, it would be greatly of use. Thanks.
