https://tinyurl.com/22earn64 Anyone have a plausible explanation for this?

https://tinyurl.com/2jfxaz9n I realize I should have made the contract but this has to be a database bug, yes? I'm going to have to make five clubs to justify not bidding game.

GIB has pandemic fatigue. It's been eating way too much takeout and has decided, "No more takeout!" https://tinyurl.com/2dpplg6k

Are you saying that the robot bids differently when it has a robot partner? Because in OP's example, the robot passed its partner's 2S bid.

I wouldn't preempt with this hand. Too much defense. But given your preamble, I'm going with 2S.

Why pass? I'm reminded of a question often asked of Richard Dawkins. "What if you're wrong?" His usual response is "What if YOU'RE wrong?" Both passing and bidding have obvious risks associated with them. What are the possible risks of passing? 1. You might miss game if the hand gets passed out. I suspect, though I'm not sure, that simulations will show game is unlikely when this happens. 2. You might go down, undoubled, in a 5-1 fit when you can make some other part score. However, when playing five card majors, your partner's MINIMUM number of spades is 5. When you hold a singleton spade, I'm pretty sure partner's average number of spades is closer to six than it is to five. What are the possible risks of bidding 1NT? 1. Your partner may have a strong hand and jump the level of the bidding into a contract your side cannot make. There's a non-zero chance you will be doubled if you get too high. 2. You give up the chance of being able to defend. The answer to whether or not to bid is anything but obvious.

The robot bidding changes once in a while. Whether it is improving is debatable.

When the hand is displayed, it had switched me to be declarer but I was actually South. I made a two suited takeout double and the robot, holding four hearts, opted to bid 1NT without a spade stopper.

It's mostly that the level of play online (not just in free tournaments) is abysmal. This results in a greater standard deviation of results. Combine that with the few number of boards and you end up with what you see.

South opened at all the other tables?

I expect the robot to bid 3H after 2N, like any sensible player would do.
