First move stats, 13x13 hex

This is based 13x13 hex games played on Little Golem. The four numbers in each cell are

    number of games
    compensated win percentage
    actual win percentage
    swap percentage
See below for more details. The column labeled "-nnn" is for games in which both players have a rating of at least -nnn. (I use custom ELO-based ratings in which the strongest player has rating zero and all other players have negative ratings.)

-200-250-300-350-400-450-500-550-600-650-700-750-800-850
