I'm not sure of the accuracy of the bot ratings but a bot does not play in the same way as a human being. It is artificial and so will make deliberate errors to reflect its rating and also play at about the same level throughout the game. A human player of 1300ish like yourself might be lacking opening knowledge but good at seeing tactics. Or strong in certain openings but not others. Perhaps a good endgame player when it's just king and pawns but unsure how to convert if its rook and pawns vs bishop and pawns. Capable of playing excellently for big chunks of the game but with a couple of big mistakes dotted in there etc etc. Its much more variable, some games playing very well, some games playing not so well.
Why is it Easier to Beat a Bot?


This reminds me a lot of Lc0. The best endgame troll ever.
At your level, computer blunders are very "random". Unlike human games which tend to have genuine oversights, computers throw in weird, unexplainable moves (like a knight on g4 suddenly captures a pawn on h2 for no good reason).
