What Does Nf3 Mean in Chess?

Every move in algebraic notation has two parts: the piece and the destination square.

So Nf3 = "a knight moves to f3." That's it. The formula is always piece letter + destination square.

In Standard Algebraic Notation (SAN), the piece letters are K Q R B N — King, Queen, Rook, Bishop, Knight. The Knight gets N because K is already reserved for the King.

A useful memory aid: the N is the second letter of "kNight."

Other languages use different letters. In German, the knight is a "Springer" (S) and the bishop is a "Läufer" (L). If you're reading an older German chess book, the letters will be different — but the square names are the same.

A chess board has 64 squares. Every square has a unique two-character name: a file letter (the column) and a rank number (the row).

White's pieces start on ranks 1 and 2. Black's pieces start on ranks 7 and 8. So f3 is in White's half of the board.

The best way to lock in the coordinates is to drill them. The Square ID drill on ChessNotate shows you a square name and asks you to tap it — coordinate memory becomes automatic after a few sessions.

Here are moves you'll see at the start of almost every chess game, decoded the same way as Nf3:

Games are written as numbered move pairs. White's move comes first, then Black's:

Once you recognise Nf3, every other knight move follows the same pattern: N + destination square. Nc3, Nh4, Nd5 — all read the same way.

If both knights could move to the same square, a file or rank is added after N to clarify which knight moves:

You'll see this in the middlegame when pieces are active and doubled. It only appears when the game requires disambiguation — most of the time plain Nf3 is unambiguous.

Reading Nf3 fluently means you shouldn't have to stop and decode it — your brain should recognise it immediately, the way you read words without sounding out each letter. That takes drilling, not just reading about it.
