Oldrich Duras (Black) Puzzle: Capture — Knight Fork
Capture tactics begin with a disciplined material count. Here, an advanced enemy knight attacks two higher-value white pieces at once, creating a fork and making passive defense unattractive. The key is to notice that the forked knight is itself vulnerable to a pawn capture. Removing the attacker immediately ends the double attack and transforms a dangerous-looking position into a substantial material advantage. This is a classic middlegame lesson: a tactical threat may also be a hanging piece.
