ChessWorld.net, founded in 2000, is an online chess site.Most games are not decided by exotic combinations. They are decided by a small set of core tactical motifs that appear again and again in real play. Master these, and you’ll win far more games — even without deep calculation.
One piece attacks two or more targets at the same time. Knights are especially dangerous forkers, but any piece can do it.
Most common beginner winA piece cannot move without exposing a more valuable piece behind it. Pins often paralyse pieces and allow slow pressure to build.
The reverse of a pin: a valuable piece is attacked first, and when it moves, a lesser piece behind it is captured.
A piece moves out of the way, uncovering an attack from another piece. Extremely powerful when combined with tempo.
A single move creates two threats at once. Most tactical wins are really double attacks in disguise.
Forcing a defending piece away from a critical square or duty, often by sacrifice.
Luring a piece onto a square where it becomes vulnerable. Often used to expose the king or enable a fork.
Blocking the line between two enemy pieces so they can no longer defend each other.
A defender has too many responsibilities. Attacking one duty causes another to collapse.
An unexpected in-between move that changes the evaluation of a sequence. Commonly missed — and very powerful.
Two checks at once. The king must move. Often leads directly to decisive attacks or checkmate.
A series of discovered checks that force repeated captures. Rare — but devastating when it appears.
