# Chess Squares Most Often Moved To Graph

Chess Squares Most Often Moved To Graph

The squares of this graph represent the squares of a chess board. The a1 square is located at the bottom left corner. The brightness of the squares indicate how often chess pieces were moved there. The brighter the square, the more often chess pieces were moved there.

The data is from 310670 games, consisting of 74425971 piece moves, played by 230 well known players. The games were obtained from pgnmentor.com/files.html on 19 July 2013. An unknown number of these games are duplicates. Castling moves were noted only by the squares to which the kings moved, not by the squares to which the rooks moved.

I compiled this data to find out if the 4 centre squares (d4, d5, e4, e5) were the most moved to, and to find out if the lesser moved to squares "evenly leave the centre or not" in a circular way.

The most moved to squares were d4 and d5, followed by f6, then e4 and e5.

The 10 most moved to squares (d4, d5, f6, e4, e5, f3, c4, c3, c5, c6) form the shape of the letter K.

The g file stands out from the f and h files.

All four corner squares were the least moved to, although there were 13% more moves made to a8 and h8 on black's side than to a1 and h1 on white's side.

The graph is somewhat symetrical vertically, however b5 and g5 are slightly brighter than their vertically mirroring squares b4 and g4.

There were 6% more moves to squares on black's side than on white's side.

There were 4% more moves to squares on the queen's side than on the king's side.

Of all the games, 103726 were won by white, 70190 were won by black, 136671 were drawn and 83 were marked with an asterisk (*) character. 15080 pawns were promoted to queens, 269 to knights, 133 to rooks, and 60 to bishops.
