Occasionally I find myself completely baffled by a robot’s choice of bid. I’m not talking about the challenging-to-program scenarios where judgement would help, but actions that are mystifying in any universe. I thought it might be helpful to the robot programmers to post these auctions, so that they can iron out bugs: https://tinyurl.com/2oaf43zc Contributions welcome.

I've played and read about bridge for ten years, but I was stumped by this seemingly basic question from a friend: [hv=d=w&v=0&b=8&a=1cppd2cpp2np]133|100[/hv] Are North's calls all natural here? If system is on - would it still be on if North had volunteered 2♦ directly over 2♣? [hv=d=w&v=0&b=8&a=1cppd2c2dp2np]133|100[/hv] Thanks.
