Prerequisites Str 13, Ride 1 rank, Mounted Combat, Power Attack, Improved Bull Rush, base attack bonus +1.

Benefits

When charging an opponent while mounted and wielding a lance, resolve the attack as normal. If it hits, you may immediately make a free bull rush attempt in addition to the normal damage. If successful, the target is knocked off his horse and lands prone in a space adjacent to his mount that is directly away from you.
