I was recently in a 3-way where one participant in the 3-way announced that they were tired and were dropping out. (This thread relates to a game, not my evening proclivities.)
As if to emphasize the fact they were dropping out, they missed two turns. The other participant in the 3-way and myself were locked in a furious struggle and so simply side-stepped the departing participant rather than lose energy confronting his, presumably, uncontrolled armies. With our own resources depleted, the dropping player suddenly re-emerged, seized control of his armies and won the game! ARGH!
My other opponent was quite put-off by this. I thought it was a cunning stratagem. What you all think, gang?
