Sounds like both players didn't die at the same time then.

I think there is an edge case where both people die at the same time, but one is about to make a move and drops the piece as they die, and it lands on the board. Is that move valid? Or not as they are already dead when it lands?

Typically there will be a clock involved, your move is completed when you push the button on the clock. Merely dropping a piece on the board doesn't complete your move.

However, I can see a situation where the player dies and falls on the clock, pushing his button.

> Is it possible for a position to occur in a legal game of chess where all pieces and pawns are on the board, all of them are on their original squares, and white does not have the move? No, and that's quite easy to prove: With all pawns on their original position, the only valid moves are by knights and rooks, and for each such move the moving piece changes the color of space it occupies (for rooks that's because t…

You are 100% correct that if a position is ever reached where everything has returned to the initial position, white must have the move. But note that I asked if white has the move any time a position occurs where everything is in its initial position, and so we must also consider the initial position before any move has made. When the pieces are in their initial positions before the first move has made, does white h…

The last time I studied chess in any serious way was like 40 years ago. All I can answer is which side has their turn to move in "returned" position, but the fine details of whether they have to make that move or can claim a draw is well beyond my expertise, sorry.

Does this imply killing the opponent is a viable strategy in chess?

Not quite. There is also a "rules infraction" where failure to adhere to the laws of chess OR the event regulations can cause you to lose. Murdering your opponent will almost definitely be considered a rule infraction. Although there might be some edge cases if the murderer was an absolute ruler of the current country. Or maybe if you happened to kill your opponent in self defense somehow.

Makes perfect sense. You can't win king vs king+pawn ever. As such even if opponent died in such situation you don't get win.

King+pawn vs king can only be won if the other guy makes a mistake. However, the other guy can make a mistake. The draw situations are king+knight vs king or king+bishop vs king.

The K+P vs. K scenario being discussed is not the one where the K player dies (loss, because K+P could have won). It’s the one where the K+P player dies (draw, because K could not have won).

K+N vs. K or K+B vs. K are already an automatic draw regardless of the players’ ability to make future moves, so death would not be a relevant factor there.
