Openings Against E4 Puzzle (Rated 914): Fork — Knight Tactic
A knight fork is powerful because one move can attack two or more valuable targets at once. In this middlegame position, Black exploits White’s vulnerable king and the limited coordination of the white pieces. The key tactical idea combines check with a follow-up attack on a high-value piece, turning temporary activity into a decisive material gain. Always examine forcing moves first, especially checks that place a knight on an active outpost.
