Pikes are mainly for anti-cav, if horseman even touch the pike line they just die instantly, and I would only use them vs infantry if you have them upgraded with weapons and armor or if they're experienced- if you do they usually can stop an infantry charge from getting in too close, but if they aren't the swordsmen will get through the pikes, like they should. You could also have your own infantry stationed in the pike formation's pikes to stop a charge.
Really, the reason why pikes were dominately used in the late medieval ages was because cavalry were previously the dominate force - but pike/crossbow/gun counters heavy cav.
Later, forces like the "Sword and Buckler" man were made to fight pike formations, getting in between the pikes and cutting up people. And then the common usage of cannon and shot really ended the dominate use of deep pike formations.
