Do you have to have check before check mate?

Answer 1

Actually, in Chess you should not have to say 'check', since players should be paying attention to the threats that are on the board. If a player in check makes a move that leaves them in check, which is illegal, their opponent may not simply capture the king. Instead, the opponent should kindly inform the player that they are in check, then the player should take back their previous move and make a legal one using the piece that was touched, if possible.

Answer 2

Never. There is no requirement to announce check or even checkmate during the game when you put your opponent's king in check or when you checkmate the other king.

Answer:

"Check" is an announcement to your opponent that you are directly attacking the opponent's king. Although it is not necessary it is usually said as a bit of a brag - a "take that" statement. As chess is in part game of psychology, worrying your opponent with the announcement and angering him by the implication that he's such an inferior player that he'd not notice the check unless you told him is a useful tool.
