A fork attacks multiple targets, but it only works if the attacking piece reaches a useful square and survives the opponent’s response.
What to do
List the candidate fork squares, check their occupancy and calculate forcing replies. Prioritize targets that create a real gain rather than counting attacked pieces alone.
A mistake to avoid
A fork can fail when the attacker is captured or one target responds with a stronger threat. Finish the line before declaring a material win.
A detail worth checking
Distinguish checks from ordinary attacks among the fork’s targets. A king attack constrains the response differently from attacking two loose pieces, which can determine whether the second target can escape.
Try this practical check
Solve a small set of verified fork puzzles slowly. For each, write the opponent’s best reply and the material situation after the sequence ends.
