The Halosar Trap is a tactical sequence in chess named after Hermann Halosar.
It arises in specific positions where White can create an immediate and decisive threat against Black’s king.
This trap has fascinated players for years, and it’s not only an interesting historical footnote but also a practical tool for players of different levels.
Let’s look into the details of this trap, exploring its move order, theory, variations, history, and its relevance for beginners and intermediate players, as well as its occurrence at the Grandmaster level.
