Depends on what you are playing. You are a human that can deviate from a path. The bot is programmed to play a certain way and can't. Did you play out a line that is main theory or did you try to trip it up? Even if you got to say move 40 out of a 60 move game, it is programmed to play like a 1900 and not a 2500. It is going to make a mistake.
It would be interesting to see the actual game and whether or not you had takebacks.
Whoever it was was pretty generous.
I am 1400 and worked my way though the bots for fun, and now playing games with Miguel (1900)
There is no way humans with the ranking of the bots would be making some of the mistakes, and seriously i would not back myself to beat any human over 1700 (my best win is v 1540)
But I have worked my way to Miguel after feeling i have the upper hand against all the preceding ones (for some reason Isabel put up a lot of resistance, maybe because she is programmed to be good at end games)
A lot of the others are terrible at end games,.
Miguel couldn't figure out how to mate my king with his queen and king and gave up a 50 move draw much to my amazement.
Even a 1000 player could do this , a 1000 player would be more likely to stalemate or hang the queen.
Look , its all good fun, and good practice, but i am just a bit bemused
