True. And really, I was thinking more of the 'super lop sided, no way to possibly lose unless you just have a brain aneurysm in the middle of making a move' type games.
For instance, I have played numerous games in which I was forced to go through entire R+K vs lone king mating routines. That is incredibly annoying and time consuming when you only have two 'conditional move' lines like I do.
a) Willing to accept rematch offers freely (or decline for any reason other than their refusal to resign in the last game, e.g., rating difference is too large).
b) Stick them on your permanent 'do not play' list.
c) Stick them on your 'do not play' list and send them angry messages afterwards chastising them for wasting so much of your time.
d) Other
P.S., this question is targeted solely at correspondence games, where their is theoretically no time pressure to influence play. Live games are not applicable unless the example is just egregiously bad.
