Memechess

Fully automatic chess bot with extensive configuration and scripting subsytem.

Configs

Every config consists of the events and the following fields: name, kind and time.

Name

Stands for the displayer config title and thus must be unique.

name = "My bullet config"

Kind

Stands for the kind of config, possible values are: [ckRage, ckLegit, ckAdvisor]

kind = "ckRage"

Time

Array of supported chess games timings, valid values: [ctUltrabullet, ctBullet, ctBlitz, ctRapid, ctCorrespondence]

time = ["ctBlitz", "ctRapid"]

Note: if you specify ctCorrespondence, then your config wouldn't be able to use my_time and enemy_time variables in formulas.

Events

Starts with a [[events]] array specifier. All further statements go on the next lines.

Every config must have 1 or more event section. This section must have 4 fields: condition, delay, thinktime and elo Events execution priorirty are top-to-down. That means that most upper events gots evaluated first. If condition formula didn't matched by operator, event will be skipped without another formulas evaluation.

Formula

A math formula which gets evaluated. Available operators are: +, -, /, *, %, ^.

Every formula can use any of the following variables:

my_time time that player have left by the last opponent move.
enemy_time time that enemy have left.
my_score is a last position evaluation score sent by engine.
enemy_score just a negative value of my_score

Condition

lhs is a left formula for operator comparsion
op operator which perfomes the comparsion: [<, >, <=, >=, ==, !=]
rhs same as lhs, but stands in the right side of comparsion

Example condition:

condition = {lhs = "my_time * 2", op = "<", rhs = "30"}

Activates when player time left multiplied by 2 is less than 30 seconds.

Note: you can use any formula in lhs as well as in rhs.

Result vars

delay a time that bot will wait before sending move to chess server. Note: delay activated only after engine has sent bestmove.
elo abstract value that specifies "strength" of the engine next move.
thinktime time that engine will have to think on its next move. (Propably will be removed)

[[events]]
condition = {lhs = "my_score", op = ">", rhs = "500"}
delay = "100.0"
elo = "500 * 3"
thinktime = "50.0"

Scripts

Work in progress.
