Assess shows you the rating changes that will occur if you win, lose
or draw against another player. Just type "assess player-name". To see
the rating changes between two other players, type "assess player1 player2".
To see the rating changes in a game you are currently playing, just type
"assess". Assess also lists the current rating of each player, in each
of the rating categories.
For example, "assess Hawkeye Smallville" might give:
In this example, if Hawkeye beats Smallville in Bullet, his rating
should go up 13 points. (Smallville has not played Bughouse, and
neither of them have played Loser's, which is why the assessments
in those categories are so high.)
