First 3 way chess game

I don't know. it might depend on scoring.
if scoring for a win is 1-0-0, we might just split the point.
if scoring for a win is 1-.5 -0, then mf92 thon we continue to fight for the half point.
btw: that second scenario was 1 for the checkmating player; 0 for the check mated player; and .5 for the "other player/"
