I like to make it as difficult as I can for my opponent to win so I often fight on in a lost position. Finding a move which surprises your opponent and generates some counterplay is good fun. But if the lost position is sterile then I am happy to resign.
I always play on a move or two (at least) after a bad blunder. So that disappointment does not cloud the judgement.

You get rainbow-kitty brownie points if you can tell me what that's from.
OMG dude was that The Old Man and the Sea? I read this like a month ago!
