I am only about 700 rating, having been given 667 as a starting point. I went down to c400 and have only got back up because I have never resigned, and also because I continue games against the computer when my opponent resigns. You never know when a player will blunder. Some people resign the instant they blunder their queen, but I have often lost from being a queen up, so it is not always the best plan. It is perfectly within the rules to play until the end of the time. I've come back in endgames many times, from as much as -17 in material on one occasion, as I am much better at these than openings, and the clock is also a factor ( I play 10mins mostly ) and if time is limited, then them's the rules afaic. I often lose from having taken too much thinking time early on so that works both ways. I am sure it is very different for folk in the 1600+ bracket, as one can be much more certain of the likely outcome. I've also never regretted declining a draw, even if I lose I usually learn something.
AGREED AGREED AGREED +100000
And on one hand I could draw a bishop and non rook pawn vs king to a 1000 ...
