I am the organizer of the Montpellier tournament (actually held in Sète , a
resort city at 30 kms), ans so I could introduce (for the first time ever)
my proposal of "declared komi", which I reproduce below (as it will be
explained to the players tomorrow) ; I hope to be able to report the results
Sunday evening  (GMT) ...

*********************************************
The "declared komi" system

1) Every player in the (beautiful) Montpellier tournament makes known at
registration a number (integer or half-integer) called his "favorite komi"
(fk). If he forgots (or declines to do so), his fk is settled at 5.5

2) For every  even game, the "real komi" (rk) is the mean of the "favorite
komis" of both opponents.

3) The player with the larger "favorite komi" begins (and plays with black);
the komi of the game (i.e. the compensation given to White) being obviously
the "real komi" (rk). In case of equality of fk, colors are drawn
(randomly?) by Gotha (the Luc Vannier's organising program).

-------------------------------
Commentaries

1) Using this method, let's say that A declared a fk of 8 and B a fk of 4.
This means they feel the game is fair with those respective komis. The
procedure gives a real komi of 6, and A begins.  A should be satisfied, as
she must pay only 6 points to be Black while she thought this advantage
should cost her 8 points ; B should be equally satisfied, as he gets a
compensation of 6 points, and was prepared to receive only 4.

2) Some similar systems have been criticized for introducing a psychological
dimension (a poker game) in the bidding period: let's say A  knows that C
hates playing with White, and is willing to declare 12 as fk to be sure to
get Black. A has then only to propose 11.5 to get White and a komi of  11.75
points, while she could not hope for more than  8 if C knew A's fk in
advance.This is the main reason for point 1) above : no such kind of
manipulation is really possible, as every player must declare his fk before
knowing who will be his opponents.

3) Of course, if rk is an integer, the problem of drawn games ("jigos") is
back.
  But is this such a large inconvenience in practice ? Anyway, Gotha manages
it perfectly...
