Hey AlC, remember that game Nimz had against "Dracula" ? He resigned immediately before she got banned! how embarrassing!
Funny you should bring that up...my other game vs Drac is now my "highest-rated" win - which is a forfeit win of course since her PC was mopping me up at the time - so maybe everyone should play on until they're mated on the rationale that their opponent might get kicked out for cheating first
Probably not, unless they have enuff common sense to at least be able to separate potential cheats from players who are just better than they are or who just outplayed them in a far from perfect game
cool Nimz, you got the best of both worlds there, it was a funny story when you mentioned it before. but you did the right thing nonetheless.

As you will be stronger player, you will know when to resign, and when playing on. This resign problem is everywhere, I am for example playing an online game, where we both have 4 pawns, and I have a rook. Why does not my opponent resign? He thinks that I can't win that? No, he is simply just a lower rated player, who does not know when to resign. Every player has stis stage of his chess career I think, when he plays until mate. (even if the position is K+Q vs K.) But everybody becomes better, they will realize that is was a foolish thing that they did not resign in the past at certain positions. So they will resign from that time if they have to.There is other game, in that there are some pieces on the board, but I have Queen against a rook, and that is still going on...
"Piece down in a symmetrical position, it's probably over. Piece down in a muddy position with lots of imbalances where there may be promotions it may be worth carrying on."
It is a very good definition.
"So you lost a piece, why not train your defensive skills and see how you can make it the most difficult."
You should not "train" your defensive skills with a piece down. You cannot protect your position, if you are a piece down. Even if your opponent can break through your defence, he will simply exchange pieces, and he will have an extra piece and you will have nothing. So similar position should be played, if you have a good counterplay, if you have no, then just resign.
