What is traxler counter-attack?

Traxler counter-attack is a chess opening strategy that involves sacrificing a piece to force the opponent's king to move from its original position, then launching a swift attack against the enemy king with a series of powerful and coordinated moves. This tactic is often used by Black against White's move 4.Ng5 in the Two Knights Defense, or against White's move 5.d4 in the Four Knights Game.

The Traxler counter-attack is considered a risky but effective strategy, as it allows Black to launch a surprise attack on the unprepared White king, often leading to winning material or even checkmate. However, it requires careful calculation and precise execution, as any mistakes can quickly turn the tables in White's favor.

The Traxler counter-attack is named after the Czech chess player Vitezslav Traxler, who used this opening strategy in the 19th century. Nowadays, it is still a popular and exciting opening among chess players of all levels.
