How each piece moves
- King — one square in any direction; participates in castling.
- Queen — any number of squares along rank, file, or diagonal.
- Rook — any number of squares along rank or file.
- Bishop — any number of squares along diagonals.
- Knight — L-shape (two plus one); jumps over pieces.
- Pawn — forward one square (two from starting rank); captures diagonally; promotes on the eighth rank.
Special moves people forget
Castling
Move king two squares toward a rook; rook jumps to the other side. Requirements: neither piece has moved, no pieces between, king not in check, king does not pass through or land on an attacked square.
En passant
If a pawn advances two squares and lands beside an opposing pawn, that opposing pawn may capture it as though it moved only one square — but only on the immediately following turn.
Promotion
A pawn reaching the far rank becomes queen, rook, bishop, or knight (almost always queen).
Opening principles for casual games
- Control the center with pawns and pieces (e4/d4 or c4/Nf3 systems).
- Develop knights before bishops; castle before launching a flank attack.
- Do not move the same piece twice in the opening unless recapturing or avoiding material loss.
- Connect rooks after castling; rooks belong on open or half-open files.
Browser-specific tips
On mobile, use the built-in move list to review the game — small screens make blindfold calculation harder. If you undo by mistake, use the move list to step back mentally and replay from a stable position. For serious practice, set a timer externally; the hub board does not enforce clocks so casual play stays frictionless.
