FICS formula

Abstract.

This article is based on FICS help file http://www.freechess.org/Help/HelpFiles/formula.html
Formulas are very useful to filter users in all ways:
1. Filtering seeks in main console,
(only if seek is set to 1:    set seek 1     )
2. Filtering seeks and using sought command.
3. Filtering games automatically and immediately, using getgame f command. This command loads game board automatically if users seek fits your formula(probably the oldest seek is priority).
Some tips. Formula can have so called "f-variables", named from f1 to f9.
Formula variables can look like this: "1","2", "1minutes", "120", "time", "ratingdiff", or so, but they can be formulas itself, e.g. "time>2", "ratingdiff>-300". Usually "f-variables" are(or looks like) less complex then formulas. Not all logically correct "f-variables" does their job. The more complex variable is, the less possible that you will get the results you want(it just might be, that only a part of your variable will be accomplished). As I discovered, it is best thing, that "f-variables" are of only one type, e.g. variable setting:
set f1 ( (time=2) & (inc=0) ) | ( (time=1) & (inc<=1) ) | ( (time=0) & (inc<= 12) ) is well taken, because clock setting type (time and inc(increment))is used.
But some parts, including "rated", of such a complex "f-variable":
( (time=2)&(inc=0) )& !atomic & !losers & !computer & rated & ( rating > (myrating - 150) )
on my computer was ignored. That's why it is best your formula variables to have somewhere written.

Fast seek formulas

seek 5 0 u 2000-4000
To ask for some color is better just "seek" with certain color
: seek white f
Other formulas
set form time=10 & inc>=5 & inc<=15 & f1 & chess
set form etime<3 & f1 & chess
set form (etime<3 | (!chess & etime<=10)) & f1

set formula chess & unrated & time>1 & time<=3 & inc=0 & white
set formula (chess & unrated & time>1 & time<=3 & inc=0) | (board(fr)|board(4)|board(3)|crazyhouse & rated & etime>=2 & etime<=4)
set formula (chess & rated & etime>2 & time<=5 & inc<=5) | (chess & unrated & time>1 & time<=3 & inc=0) | (board(fr)|board(4)|board(3)|crazyhouse & rated & etime>=2 & etime<=4)
set formula (chess & rated & etime>2 & time<=5 & inc<=5) | (chess & unrated & time>1 & time<=3 & inc=0 & white) | (board(fr)|board(4)|board(3)|crazyhouse & rated & etime>=2 & etime<=4)
set formula (chess & rated & etime>2 & time<=5 & inc<=5) | (board(fr)|board(4)|board(3)|crazyhouse & rated & etime>=2 & etime<=4)

In those two formulas, second parts, where denoted "rated" and "unrated", does not work.
set formula ((chess & time>1)|((board(fr)|board(4)|board(3)|crazyhouse) & inc=0)) & ((time<=5 & etime>2 & inc<=5 & rated)|(time<=3 & etime>2 & inc<=3 & unrated & white))
set formula ((chess & ratingdiff>-100)|((board(fr)|board(4)|board(3)|crazyhouse) & ratingdiff>-200)) & ((time<=5 & etime>2 & inc<=5 & rated)|(time<=3 & etime>2 & inc<=3 & unrated & white))
