What bot is the worst bot in history?

Mittens…

Probably not martin fr

By rating its probably Mittens. Rating one 1 ELO. For performance, its almost certainly Martin.

Martin as a bot that has stayed, that is.

engine 1 (250) is tied with martin for 'strength'. 😄

both had rather sad game ratings (350 & 550). 😬

With an engine when you put the strength below 1350 elo , the engine inject artificial error. So 350 you end up with game that don't make much sense.

Camille put rule in place and a rule being a restriction, will usually limit the elo level of the engine, so you can have a 2500 elo engine playing like a 1000 elo one but without making any mistake.

The bots rule are : the first 7 moves are all pawn push (except if legal obligation or positive exchange which will not happen vs stockfish), and the 4 central pawns are valued at 2 not 1, the laterals pawns at 1.5. So the bot will push the lateral pawn preferentially because the central one are just too valuable.

Camille in white at 2500 elo get dismantled by Stockfish at 1500 elo (one of many games). And amazing at move 11, the eval was close to 0.
