@oldspooky, the adaptive bots are like that. they wipe you off the board, then give you the advantage on a silver platter and make you not want to play chess. the rest of the bots are decent.
I have never seen nelson hang a queen outright, but he does hang queen traps which is about the same.
I think the bot "Nelson" is probably about 950-1050 rapid. what do you think?
