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"
