Explanation and bidding won't fit.
Bug ?

And, why didn't West go ahead and bid 2♠?

Looks like glitches on the road. 3♥ promises just 6TP, and GIB has 8TP, so it needed to consider some more active continuations, like 3♣,3♦, 4♥ etc. It went wrong here so it will be investigated for fix.

After it was released from the obligation to bid its suit by South bidding 2♥, none-forcing 2♠ would require bigger minimum of points.

Why should that be? West was the one who created the "obligation" by bidding 2♣. Bidding 2♣ shows a willingness to bid his suit at the lowest available level; I don't see what has changed by the time the bidding gets back around to him.

Maybe it's because opener showed a maximum?

That certainly could be why. Should it matter? (That's an honest question, not an argument.)

My guess is that this auction isn't in its database, and it resorted to simulations, and decided it wasn't a good idea to bid with a minimum hand and a poor suit.

3♥ with such a sequence should require more than 6-7 TP- that's a pass.

Not bidding 2♠ from West is definitely a big mistake but yea there are crazier stuff going on in Gibland (e.g. the 3♣ bid).

West hand is not so powerful so fight with when 2♥ is given.

6th ( which is promised by default), but in general not so good suit if partner has singleton.

If we review on closed hands, not on open, there are some thoughts.

Partner is passed hand, so how if you're East will distinguish invitational hand from part-score fighting hand?

Also, when you gave forcing bid, like conventional overcall or Double, and when your partner bids the forced bid ( which kind of limited ) or has no desire or chance to bid at all and you bid again, what hand should be that?

That's was what i meant about West is released to give a call. 2♥ gives West option to review its hand once again. Bidding 2♣ here or giving Double is not automatic trigger to explain again your hand on next round if you don't have extras to do so.

East has also option to give active bid like biding his own suit, or 2NT invite, so 2♦ shouldn't be counted as 8+HCP and 3+fit elsewhere, right?

so a hand like ♠AKTxxx ♥x ♦Axx ♣QJx looks much better to compete with over 2♥.

Or having at least 7th spade.

OTOH, 3♣ is certainly a glitch, which could be fixed.

Let's agree to disagree. I think more of fighting for a partscores (especially when partner is a passed hand and they opened 1NT) than you do, apparently. I also think less of trying for game in these situations. Cheers.

edit: I admit that my "definitely a big mistake" was an overbid.
