Check first then opponent Check-mates: who wins?

wgati

If I am playing a real-life 30-minute game with a clock and my opponent does not respond to a check and checkmates me in the next move, do I win or does he?

If youre opponent is in check, and they check mate you.  That is an illegal move.  They need to take the move back, and either move out of check, or capture the piece that is putting them in check.

With the piece they originally moved, if possible.

Well, the whole Idea of chess, is that the King must not be captured, and whoever captures the King first wins, thus a checkmate is when there's is no possible move you can make without your King getting eaten. Your opponent lost if he is in check and it's your turn, because it doesn't matter if you're in checkmate or not, you can simply eat his King first. But technically, he made an illegal move, and he must take back the move.

Only way that could happen is if your opponent moving his king out of the way, then leads to some kind of a discovered attack on your king, which is also checkmate.

 

 
 In this example the black king is in check. However the king could always just capture the bishop and move out of check while also putting the opponent in #.

Of course they don't win.That would be an illegal move.If your opponent didn't know they were in check,you probably didn't announce check or perhaps you announced check but they just forgot about it while thinking about their next moves. (move in this situation as it was a single move after the check).In some chess variations,doing this results in disqualification of the side that was in check.If the opponent isn't disqualified due to your game perhaps being a casual game,you can clarify for them that their move is prohibited as their king would get captured first.This would be false assuming the checkmating move gets the opponent out of check somehow,which is what sinha here demonstrated.Black moved their king,getting out of check,and made a discovery checkmate towards white king at the same time.

Now I'm confused

It's not that complicated. If you have someone in check but they can move their King out of check or another piece to protect their king and in doing so places the other person in checkmate. If the other persons king is in check it's an illegal move to place you in checkmate if they are still in check.

People hear, only what they understand, and say according to their understanding. It's quite simple.

it is like two cowboys who shoot each other, and a time machine. When the first cowboy gets hit (or 'checkmated') by a bullet, the time machine gets activated and freezes the time. And the game is over. The other cowboy doesnt die, even if a bullet is centimeters before his face.

Nice explanation , very surrealistic.

Never thought about it quite that way before, but there is a lot of truth in what he's saying!! lol
