First Move: Player 1: 3,5 Player 2: 6,1 3+5+6+1 = 15 Second Move: Player 1: 3,4 Player 2: 6,2 3+4+6+2 = 15 unless your system would never come upon two players moving in such a way (that would mean, only one player can move per second) then yes that would probably work. but otherwise it would not. chris.
