Here I'm clearly looking for second round control in diamonds and the bot goes to slam without one. Sure I could just close my eyes and bid 6 but I would never do that with a human partner.
In the other hand (which I can't find at the moment) I went to Blackwood. The robot bid 5♣ showing 0 or 3 key cards and 0 was still plausible on the bidding. I sign off but the robot actually had 3 and failed to correct. I've had this scenario come up before from the other direction and the bot signed off, knowing that I would raise if I had the extra key cards.
