If you read the 2♠ description, it mysteriously says 3+♣. But it seems it was bid meaning spades here. I think the description could use a fix.

That being said, it's possible it is normally 3+♣ and that it just happened to get a weird sim or something where it felt it was worth bidding this even with only 2♣ so this may be incorrect.

Under the assumption that the double shows 4+♠, and that you'd never want to play spades now. 2♠ is seemingly a cue-bid in support of clubs. Why 2♠ as opposed to 2♥? I mean, that depends on your agreements, but maybe the robots are programmed to use the most expensive cue-bid possible without passing the suit they are supporting? Perhaps it was showing the spades stoppers that it held.

It's an imperfect bid, showing the strength, but you surely must know you're annihilating 2NT here. You should double.

I guess it didn't bid 2NT due to the diamond shortness. But, that's really the bid that best describes the hand in that situation, other than maybe redouble?
