Comments.Text: Ok. I get what you mean. Your opponent made an illegal move. Both of you should go back to the position before the invalid move and try again. However, in a standard blitz game, you could immediately claim a win. In any case, this has nothing with checkmate.

Comments.Text: Why my opponent is said to make an invalid move? It is invalid to move king such that it ends up in check. This is official Chess rule. This doesn't imply that "if Black King (say) is in check and Black player forgetfully use his turn such that check is not broken" is invalid. Does it?

Comments.Text: Not preventing a check while in check is illegal as well. I think someone body here will give you a good example, hopefully with some nice diagrams.

Comments.Text: @SufyanNaeem It _does_ mean that huis move is invalid. If you are in check, you can legally do only three things: 1) move your King out of check, 2) block the check with your other pieces, 3) take the checking piece. (In case of double check obviously 2 and 3 don't work.) If you do anything else in your move while in check, it's illegal.

Comments.Text: @Sufyan It **is** illegal for an opponent to **not** get his king out of check (if possible) whenever it is in check. That is why a non-checkmate check is called a "forcing" move.

  (Asked by: username_0 on 2016-01-05)
  
  Checkmate means king is in trap and there is no way out.
  
  If it is my turn and opponent's king has a way out from trap, am I said to win the game?
