Is it neccesary to say CHECK prior to checkmate?

Question

and if the king is in check and both didnt know, is it checkmate if you notice on your turn?

Answer 1

There is no rule requiring you to say "check" when your opponent's King is in danger. In fact, you might get penalized at a tournament for doing that because you're not supposed to speak to your opponent.

It is your opponent's responsibility to respond to the check. If he does not, then a penalty can be enforced, as follows: The player who did not respond to the check, but instead made another move, would be required to take the illegal move back, and make a move with that same piece to respond to the check (even if it means the loss of that piece)....if the player can not move that piece legally, then tehre is no penalty, but the illegal move must be taken back and the check responded to.

Answer 2

Check and checkmate are two different things. You can get to checkmate without having been in check first, although rare. It is necessary to state check when the king is in check, but it is possible to orchestrate a checkmate without having put the king in check.

Check is when the king is in danger of being captured, but there is a way out. Checkmate is when there is no move that will prevent the king from being captured.

Answer 3

No you were not required to say 'check' on this occasion because there was no check involved and yes, it would have been checkmate as long as your knight was actually attacking his king and not just stopping him from being able to move it and any other piece, in which case it would have beenm a stalemate...which would have been a stupid thing to do if you were winning anyway. You are correct about the definitions of 'check' and 'checkmate' and yes, this was a fair game and you did win fairly.

Answer 4

It is not neccesary to say check, if for the second part of the question, you continued playing it would be an error, ultimately if you checkmate somebody, game over.

Answer 5

1. No, it is NOT necessary to say check if you attack your
opponent's King - it's optional. That's the rule.

2. If your opponent didn't notice the check and make other moves
didn't free his King from check, he made an illegal move. As
his opponent, you must warn him and ask him to retract the
move. That's the way it is - so it is NOT checkmate

Answer 6

haha. thats why you say check as soon as you put someone in it, or don't let them move pinned pieces. im pretty sure what happens is it goes back to the person who's in check's turn, and they must get out of check. but if your playing snap king, thats game....(snap king is where you don't say check, its up to your opponent to figure out that hes in check-if he doen't notice, you just take his king like it was any other piece (and you win the game)

Answer 7

yes. it's a courtesy notification. an average player would know without saying. If both didn't notice, i guess we are talking about novices, then i presume it is okay... it's part of the learning process. Once you are experienced enough it would be impossible not to notice.

Answer 8

It is the rules, when in check you must a piece to get out of check, the reason you say it, is to draw attention to it, in case your opponent is not paying attention.

Answer 9

AHAHAHA dude the question in the subject header is different than the question in the body...

look;
"Is it neccesary to say CHECK prior to checkmate? " - YES.

Answer 10

It is neccessary to say Check to notify your opponent that they need to move, quick.

And no, it's still check
