Andersp: Why resign? Why not play the game to its conclusion and then not play that person again if you feel they have hurt you in some way? You might as well use the game as a learninng experience, even if you were tricked into playing a machine with false pretenses. Remember, it's not the machines that are cheating, but the people that employ them without telling you in advance. One thing about a machine, it won't get impatient. You don't need to resign, no matter how far behind you are in the game. I've used this to help me understand how the various pieces move in Janus Chess. If I was playing a person in some of those games, I would've resigned out of respect to them when I losing with no chance of winning. A machine doesn't care about that kind of stuff. It just makes the moves that it calculates are best. It has no emotions or ego for you to worry about. Plus, the person that's using the machine will get impatient with you for not resigning a lost position. That'll serve them right for using a machine against you and not informing you in advance.
