Given the curious play by Jim's highly rated opponent in the first game, and the circumstance that Jim has already beaten him 4, now 5 times, I wonder if some players on lichess aren't in fact bots! I wouldn't be surprised if I heard that chess sites were trying to increase human engagement by using secretive, manipulative and underhand methods. Presumably on lichess the data gathered can't be monetised directly, but it can presumably come in handy elsewhere, or be sold to the highest bidder. But then I haven't looked into who exactly is funding lichess, nor do I ever wish to. Just a thought.
