Short Home Row Notation

Please Note! - SHRN is currently only supported on Lichess.

Although HRN is fundamentally built on coordinate notation—where each coordinate maps directly to a square—it also supports a shorter notation, much like how SAN is a shorthand version of LAN. We call this Short Home Row Notation (SHRN). SHRN is made possible by assigning a few easy-to-reach keys, located just above the home row, to the chess pieces. These are known as Piece Keys, they are also used to select the desired piece when promoting a pawn.

Piece Keys

Key	W	E	I	O	M
Piece	Rook	Knight	Bishop	Queen	King

E.g. To enter a move in SHRN, simply type the Piece Key followed by the HRN destination square. For example, the SAN move Nc3 becomes EDD, where E is the Knight and DD is the HRN coordinate for c3.

Pawns

For Pawns, only enter the destination square's HRN coordinate, and any pawn that can make a legal move to that square will be played.

E.g. Typing JF plays the King's Pawn Opening (e4).

SHRN also supports pawn captures.

Key	G	H
Action	Capture Up-Right	Capture Up-Left

E.g. Pawn JF capturing on the up-right square KJ can be typed as JFG
