Well consider another thing here, a pitchfork is a farming implement. This is not a pike, halberd, or trident... its a cheap broom handle usually less than 2m long with a cheap piece of metal fastened to the end, used for shifting hay around. In the game, peasants and looters have these because they can't afford weapons, so they use farming implements. To brace for a charge attack both hands would need to be on the shaft and the base would have to be on the ground, otherwise that thing is flying out of your hands as soon as it hits a horse.
If you really want to talk realism, a knight is trampling over a guy with a pitchfork every single time.
