I was playing in an OTB tournament in Fredicton NB, when a guy a few boards down from me had a heart attack right at the board.
After the Emergency crew came and collected him, the tournament director walked up to his board, stopped the clocks, spent a few seconds looking at the position...
... then said "He was losing anyway" and walked away.
A true chess player!
A player collapsed at the board. A doctor who was playing in the tournament rushed to examine him and announced "He is dead. But his position was hopeless anyway."
