Over the board, the moves stay the same and the procedure becomes yours. You castle, promote and press the clock by hand, a piece you touch with the intention of moving it is the piece you move, and a threefold-repetition or 50-move draw only happens if you claim it. The board won't stop an illegal move either: under the FIDE Laws, the first one gives your opponent 2 extra minutes, 1 in rapid or blitz, and the second one loses.
The rules below come from the FIDE Laws of Chess, 2023 edition, with article numbers in brackets. US Chess has its own rulebook, and I've flagged where it differs.
OTB means over the board: a game on a physical board with physical pieces, with your opponent across the table. Two players on computers in the same room don't count.
For where to play, see how to start playing chess in real life, and for OTB ratings, Chess.com rating vs FIDE. This guide covers what happens once you sit down.
Online, the software blocks illegal moves, promotes your pawn, spots the draw and runs the clock. Over the board, each of those is your job.
| Online | Over the board | Rule |
|---|---|---|
| Premoves queue your reply | Move on your turn, then press the clock; pressing early or hovering over it breaks the rules | FIDE 6.2.3, 6.2.4 |
| Auto-queen promotes for you | You choose the piece and swap it in by hand | 3.7.3.3 to 3.7.3.5, 4.4.4 |
| Illegal moves are blocked | The board allows them, and they're penalised once you've pressed the clock | 7.5.1, 7.5.5 |
| Click a piece, then change your mind | Touch your own piece with the intention of moving it and you must move it | 4.3 |
| Move confirmation and takebacks | A piece you've released on a square stays there | 4.7 |
| Threefold and 50-move draws end the game for you | You claim them on your move | 9.2, 9.3 |
| Stalemate appears on screen | The game ends at once, and you have to see it | 5.2.1, 5.2.2 |
| A draw button | Offer it out loud after your move, before you press the clock | 9.1.2.1 |
| A resign button | You declare it | 5.1.2 |
| Moves are recorded for you | In standard games you keep score yourself | 8.1.1 |
The clock's own rules, from the hand you press with to running out of time, are in how to use a chess clock.
A threefold repetition or 50 moves without a capture or a pawn move doesn't end the game by itself. The player to move claims the draw by writing the move they intend to make on the scoresheet and telling the arbiter, or by claiming when the position has just appeared (9.2, 9.3).
Touch a piece with the intention of moving or capturing it first, and you lose the claim on that move (9.4). Announcing an adjustment or touching one by accident doesn't count. A wrong claim gives your opponent 2 extra minutes, or 1 in rapid and blitz (9.5.3, A.3). The draw only becomes automatic at a fivefold repetition or after 75 moves (9.6).
Stalemate ends the game immediately, and so does a dead position, where neither player can checkmate by any series of legal moves (5.2.1, 5.2.2). That covers what sites call insufficient material, and you have to spot it yourself.
Touch the king first. Move it 2 squares towards the rook, then put the rook on the square the king just crossed, all with the same hand (3.8.2, 4.1, 4.4.1). Online, the rook jumps across by itself.
If you deliberately touch the rook first and then the king, you can't castle on that side on that move, and you have to move the rook instead if it can move (4.4.2). Castling with 2 hands and pressing the clock counts as an illegal move (7.5.4).
Online, auto-queen (a setting on Chess.com and Lichess) promotes for you. Over the board, you make the swap: take the pawn off and put the new piece on the promotion square, in either order, with one hand (3.7.3.3 to 3.7.3.5, 4.6).
You can choose a queen, rook, bishop or knight, and it doesn't have to be a piece that's been captured. Your choice is final once the new piece touches the square (4.4.4).
Stop the clock and ask the arbiter for one, which is the exact example the Laws give for pausing the clock (6.11.2). If you press the clock with the pawn still on the last rank, that's an illegal move, and the pawn becomes a queen (7.5.2).
The FIDE Laws have no article on the upside-down rook and only provide for swapping in a new queen, rook, bishop or knight, so at a FIDE event, ask the arbiter. US Chess handles it differently: as quoted on its forum, rule 8F7 treats an upside-down rook as a queen unless the player says otherwise. In a casual game, agree on it before you start, or borrow a queen from another set.
Over the board, the first touch counts, and there's no clicking a knight and then switching to a bishop.
Touch one of your own pieces with the intention of moving it, on your move, and you must move it if it has a legal move (4.3). Touch an opponent's piece with the intention of capturing it and you must capture it if you can. A piece you've released on a square stays there (4.7).
To straighten a piece without committing to it, say "I adjust" before you touch it. You can only do that on your own move (4.2.1).
The board lets you make it, and the move counts as complete once you've pressed the clock (7.5.1). The position from just before it is put back, and the arbiter gives your opponent 2 extra minutes in a standard game, or 1 in rapid and blitz (7.5.5, A.3).
A second illegal move in the same game loses. If your opponent can't checkmate you by any series of legal moves, it's a draw instead.
These count as illegal moves too:
In rapid and blitz games without full supervision, your opponent has to claim the illegal move before making their own next move (A.5.2).
Under US Chess rule 11D, as quoted on its forum, an illegal move adds 2 minutes to the opponent's clock if they claim it before their next move, and in standard games a repeat reportedly doesn't lose.
Say "I resign", stop the clock and offer your hand. The only rule is that you declare it (5.1.2).
The handshake is a custom, and the Laws never mention it. Tipping your king over is a custom too, and saying the words leaves no doubt.
Make your move, offer the draw out loud, then press the clock (9.1.2.1). If you're keeping score, mark the offer with (=). An offer can't be withdrawn, and offering again and again can count as annoying your opponent, which the Laws forbid (11.5).

You might. Player experience says your first games over the board can go below your online level, though we know of no study that measures it, as the Chess.com rating vs FIDE guide explains. The reasons players give:
Sources, checked in October 2026:
What does OTB mean in chess? Over the board: a game on a physical board with physical pieces. Two players on computers in the same room don't count as OTB.
Are over-the-board rules different from online chess? The moves are the same. Over the board you also follow touch-move, press the clock, promote and claim draws yourself, and illegal moves are penalised.
How do you promote a pawn over the board? Swap it for a queen, rook, bishop or knight with one hand, in either order. Your choice is final once the new piece touches the square (4.4.4). If there's no spare queen, stop the clock and ask the arbiter (6.11.2).
Does an upside-down rook count as a queen? Under US Chess rules, yes, unless the player says otherwise (rule 8F7, as quoted on the US Chess forum). The FIDE Laws only provide for swapping in a new queen, rook, bishop or knight, so at a FIDE event, ask the arbiter for a queen.
How do you castle over the board? With one hand. Touch and move the king 2 squares towards the rook first, then put the rook on the square the king crossed (3.8.2, 4.1, 4.4.1).
What happens if you make an illegal move? The position is put back and your opponent gets 2 extra minutes, or 1 in rapid and blitz. A second illegal move in the same game loses, unless your opponent can't checkmate you, which makes it a draw (7.5.5, A.3).
Is threefold repetition automatic? No. You claim it on your move: if your next move would repeat the position a third time, write that move on your scoresheet and tell the arbiter before you play it; if the position has just appeared for the third time, claim straight away (9.2.1, 9.2.2). A draw only becomes automatic at a fivefold repetition or after 75 moves (9.6).
Do you have to say "check"? No. The Laws define check (3.9) and never require you to announce it.
How do you resign in chess? Say "I resign", stop the clock and offer your hand. The Laws only require that you declare it (5.1.2). Tipping the king is a custom.
