Im a beginner and I play on chess.com, chess3d and a bunch of other sites. I win against the beginner bots and lose against the medium difficulty bots. Exactly what you'd expect. But I always lose against bill jr, who is supposed to be easy, yet I often win against Bill sr, the medium bot. Just a really bad engine by a bunch of unskilled programmers.
“The programmers are incompetent, stupid, lazy af. All their games of chance are rigged. They're too dumb to program the AI to win against the dumbest humans so they rig the draws. They should go back to their day jobs of data entry for min wage.”
