Why does the robot think it is a good idea to pass my 1♠ bid, which nearly always shows only 4 (because I didn't open it), with a singleton?!

[smerriman]

A better question is why you did you bid 1♠ with this hand?!

I think that folks have tried to explain this before, but the robots are bad
They are very very bad

However, even for the robots, passing 1♠ is an atrocious bid

FWIW, I think that you'll find life much easier if you rebid 2NT with that sort of hand rather than 1♠

If you want an actual answer to your question, it passed because:

a) you're using the free version, which has half of the important bidding logic disabled

b) like you personally, the free version considers HCP and total points of the utmost importance, and will never change its rules. It requires 6 HCP to bid 1NT, and 4 clubs to bid 2♣, and its system for responding to 1 level bids is broken so it doesn't realise this is unplayable until it's too late. No matter how many times people have said this is unplayable, it continues to play it anyway

But 1♠ seems very odd to me, and if you were using the full version, GIB will probably correct you to a 3-3 club fit expecting you to have longer clubs.

Because I have 4 ♠ and the robot hasn't denied a ♠ fit yet.

I don't skip major suits before rebidding NT.

Why didn't the robot bid 1♦?

Players are divided as to whether to skip spades when making a 1nt rebid.

I challenge you to find a *single* reference which agrees with you when it comes to a 2nt rebid. Continue to have bad rules, continue to get bad scores.

As for not bidding 1♦, I said this earlier - GIB follows rules blindly, and skips diamonds to show a 4 card heart suit. A very common agreement, but it hasn't been programmed to follow up appropriately.

The hand is sufficiently weak that the bit doesn't expect to be able to show both suits.

Its is prioritizing showing the more useful one

You have 18hcp - this is a 2nt rebid
