Nope. They can either be:
A) Testing to see if you can turn a won position into a win.
B) Waiting for you to make just one little blunder that can turn the tables around.
C) Wanting you to play for a mate so that they can learn something.
D) All of the above.
A win's a win. Kudos if you had a forced mate going - the journey is more satisfying than the destination.
There is one thing, that just gets me anoyed every time.
People resigning, 2 moves during a forced mate sequence. When they didnt resign for the last twenty moves when they were obviously not going to win it. I don't mind playing on an obviously won game, sometimes people forget that sometimes you do have to finish what you start. But don't rob me of the pleasure to deliver that mate when you forced me to play on for way longer then neccesary.
Are more people anoyed with this?
