Originally posted by GolubIf you hit the clock as per a normal move, your clock will stop, and you cannot then run out of time. Your question seems to imply an impossible scenario.
If I do not stop the clock (just hit it like for a normal move) when I checkmate my opponent and then run out of time, can my opponent claim the win?
Or should I stop the clocks myself to claim the win for my checkmate?
What is "correct" ?
Originally posted by GolubYou only time out if either your opponent claims a win on time or an arbiter declares the game won on time. Checkmate, stalemate, resignation, agreed draws and positions where neither side can mate all end the game immediately, and time outs cannot be claimed or awarded by an arbiter after the game has ended.
But how are you supposed to know if my time was out first, or if I checkmated in the moment before?

6.8 During the game each player, having made his move on the chessboard, shall stop his own clock and start his opponent`s clock. A player must always be allowed to stop his clock. His move is not considered to have been completed until he has done so, unless the move that was made ends the game. (See Articles 5.1, and 5.2)
The time between making the move on the chessboard and stopping his own clock and starting his opponent`s clock is regarded as part of the time allotted to the player.
If so then you have won
Originally posted by stevetoddI agree Checkmate ends the game. Your move is complete once you place the piece on the square and remove your hand from it. At that point it is irrevocable.

If your hand falls before you have removed your hand from the piece your opponent can claim a win on time but he must claim it
The problem occurs when he does claim it but after you have released the piece. It is unlikely that it can be proven any particular way and the arbiter may have no alternative but to award a draw. The solution is simple, ensure you stop you clock immediately you deliver checkmate and do not allow the hand to fall.
Of course even if your hand has fallen if your opponent never claimed a win on time you have won.
I heard a story about a strong local player in Malaysia who got a chance to travel and enter a big tournament. He was doing well against a strong IM but eventually after a long battle the game began to swing in favour of the IM. Then the IM offered a draw. The challenger was quite surprised but assumed there must be something in the position he couldn't see - so he accepted the draw. Later at the hotel he approached the IM and asked why he offered a draw from such a strong position and the IM casually responded: "My flag had dropped"
Originally posted by stevetoddThe USCF rule reads the same and also has a note appended at the end which instructs TDs that in a case where a player claims that his opponents flag was claimed prior to the checkmate being played, (and the other play claims to have played the mate first) if there are no witnesses, then the TD shall rule in favor of the mate.

If your opponent has insufficient material to mate and you run out of time then I believe this is a drawn ending.
I was in a mini tournament for parents alongside a kids tournament and my opponent was unfamiliar with the clock so I continually reminded him about it throughout our game. Having cleared all of his pieces except a Bishop as I went to get my rook organised to close to a check mate my opponent (and the crowd of kids including my own who'd gathered) starting getting excited as my flag was about to drop. When my flag did drop - just a couple of moves away from mate - he made big cheers and celebrated his "win". The tournament director corrected this to a draw and I've since become more reticent about reminding opponents to hit the clock.
