If the position on the board wasn't checkmate, then shaking hands could mean. You offered a draw, and it was accepted, or your opponent resigned and you accepted.
Checkmate declared incorrectly

I did a bit more reading up. No player is even obliged to declare "check" or "Checkmate". So if "checkmate" is declared and it's then found that it is isn't in fact checkmate, the game carries on as normal. If the player accepts that it's checkmate and shakes your hand, the game is over regardless of the position.

Agree with the Duke
When I played OTB it was always considered very impolite to announce check.
I was under the impression that u only say mate once since you’ve put an end to the game but if it turns out it was false then it should be a draw, why would it not be ?

Declaration of mate when one doesn't exist has no penalty and the game continues, unless there is some other game terminating condition on the board.
If your opponent accepts your claim of checkmate, shakes hands and signs the scoresheet, he is essentially resigning. He may be resigning wrongly, but that doesn't matter
I’m just gonna start declaring checkmate after every move

I think you will quickly find yourself forfeited from the tournament for violating the rules against harassing your opponent with phony claims
Looks like I got to stop saying check now because I didn't know that it was impolite lol

In an official match if you opponent doesnt realize it is mate by the time you have already shaken hands…it is considered a mate. It doesnt matter whether it is or is not so keep your eyes on the board

I was playing with my friend OTB today and I (believe I) checkmated him, he pronounced checkmate and I agreed. Unfortunately as I called another person over, he moved the queen (in order to reset the board) so I moved it back to which I assumes was a space to the left. When the person arrived they commented that it was not check as my queen could be taken as it was no longer protect by a knight. To no avail I tried to explain that I had likely moved the queen back into the wrong place. He then declared it was not checkmate. We did not shake hands afterward he called checkmate as we usually don't (this is school chess club so informal). Is this my win or my loss (as I walked away (did I forfeit?) as I had to revise for a test later that day) or a draw?
If it was a casual game, then it doesn't really matter. If it was a tournament game, then when you both agreed on the outcome, that's the outcome.
Hello dear chess community. What happens if you declare "checkmate" incorrectly in an OTB match and your opponent shakes your hand and you only later realise it wasn't mate? Does the game have to be replayed or does the win stand?
