As a result of extensive consultations between myself (for the US Sh=
ogi Federation) and Asle Olufsen (for FESA), we have agreed to change the=
method of rating handicap games (which is currently only done for games =
in the US). Henceforth, the value of each handicap will be a set number =
of ranks, rather than a set number of rating points. This corresponds wi=
th the Japanese practice of using the same handicap for a given number of=
ranks regardless of the level. However, our rank equivalences are less =
than the Japanese custom, as our data shows that the customary Japanese h=
andicaps to not fully equalize the chances (especially in clock games). =
Our rank equivalences (effective Jan 1 2002) will be: sente =3D .15, lanc=
e =3D .5, bishop =3D 1.5, rook =3D 2, rook & lance =3D 2.5, two piece =3D=
3.5, four piece =3D 4.5, five piece (right) =3D 6, and six piece =3D 7 r=
anks. =20
The exact implementation is difficult to explain, but basically the =
handicap gets a rating value equal to the above number of ranks at the le=
vel the players are actually at. Thus, for mid kyu players rook will be =
only 160 points (instead of the current 250), but in a game where a mid 5=
dan gives a mid 3 dan a rook, its value will be 340 points, since the ra=
nks are much wider at high levels. We believe this will give more accura=
te ratings, especially to professionals whose rating might otherwise be b=
elow top amateurs.
