I almost always play out lost games. I'm still very new (well, not new, just not very good). It's instructive to me to play out lost games to see how better players execute their middle-game and end-game strategies when ahead.
If I've just blundered away three major pieces, that's a different story. But if we're at rook and pawn vs. bishop, I want to see what happens.
I dont think it is acceptable to ask your opponent for a resignation under any circumstances. If you really think he is at a point where he/she should resign, then you should be able to win without asking for a resignation. So i say that you should drag the match out awhile longer just to make him realize the lack of respect it shows to ask for your resignation.

Well put, I totally agree...
