What is a fork?
A fork attacks two pieces at the same time with one move. Knights are the best forkers because their moves cannot be blocked. Find the fork in each position.
Tactics
What is a skewer?
A skewer is like a reverse pin: the more valuable piece is in front, and moving it away exposes the less valuable piece behind to be captured. Rooks and bishops are the best skewering pieces.
Tactics
Back-rank checkmate
When your king is stuck behind its own pawns with no escape squares, a rook or queen on the back rank delivers checkmate. This is one of the most common ways beginners lose.
Chess Thinking
Don't hang pieces
A 'hanging' piece is undefended and can be captured for free. Spotting your own hanging pieces before moving - and your opponent's - is the single fastest way to stop losing material.
