LOL, well that is a point but I'm just asking to maybe Throw his Enemy off its not Forced if he Enemy makes a few blunders I guess a Better Question might be whats the best move to maybe Delay Mate...?

Resign. Then mate is delayed by infinite number of moves.

Rc3+ then Ke1 is what I would play if I was momentarily transformed into an annoying person.

Lol well the point was to delay mate, in this case youd pretty need an IQ of dirt not to be able to find mate as white but I'd move my remaining rook to check the king, pretty much hanging him, I've seen weirder things happen a Player taking his mind off the mate to take out a few extra men.

Thanks for the Replies guys
