Overhead, thumbs facing back, two-handed downward thrust. Lean back a little, holding on with your calves, then pull yourself forward with your thighs and put your back into it.
During impact, twist the lance down and to your left (if opponent is in your left) or right, under your elbow as you pass by, then hold on and let the horse's momentum pull the lance out during your Ride-by Attack.
(You nut. This is just a game. Don't try to make any of this stuff actually sound reasonable or logical. It ain't.)
