Icelandair’s chess engine was equally brutal (well maybe only slightly less brutal). I played a couple of rounds on medium difficulty only to realize I didn’t stand a chance. I played a few more on beginner, and still lost all my game by blundering some tactics to the engine. Just before landing in Iceland I manage to get one game to the endgame, where the bot finally starts feeling like a beginner (well an advanced beginner) and I got one victory in.
