At your level, openings are not the most improtant. Just try to keep the classical opening principles and don't take unnecessary risk. It's more important to improve your vision by solving puzzles and learn middlegames strategies and basic endgame theories. You can find all these kind of things on my Patreon channel. But if you really want to build up a solid opening repertoire, you can choose a membership on my channel and learn the openings what I upload there.
Dear Chess Friends,
In this video, I’ll walk you through two of my recent online games where I successfully executed the classic Greek Gift sacrifice. These examples will help illustrate not just the mechanics of the tactic, but also the typical attacking ideas that often follow and can lead to a decisive victory. Whether you're learning the motif for the first time or looking to sharpen your tactical vision, this is a perfect opportunity to see how the Greek Gift can work in real games.
