 We also wanted to measure how close or available a pawn promotion was. We acheived this by calculating the distance each pawn was from the opponents first row (the promotion row) and summing them up. We believed it wasn't enough just to have this raw number as other pieces may have been impeding pawns from being promotion so we created another heuristic known as openPromotion. This counted the number of open spaces on the promotion row, i.e the opponents first row.
 
-Finally, we wanted values for which pieces were able to make moves and which pieces were able to make jumps. For which pieces were able to make a move, we counted how many moves each pawn and king could make and simply summed them up. This, however, only considered direct moves, not jumps, as it searched the surrounding piece for an open space. To search for a jumpable piece, we had to look at whether there was an oppinent in the direct path of a piece and whether then whether a jump over that opponent was possible.
