actully e4 or f4 always means Pe4 (Pawn to e4) or Pf4. so one idea is to fully expand it first and then parse it. Of course, you need to handle things like e2e4 and Rad4 and so on. I am also certain that if the first letter is not upper case then it is a pawn move(i.e. all the other moves must give the name of the piece that is moving) so you could change e2e4 to Pe2e4 or Pe2Pe4
