In GIB world X and then jump to 3N is like a 29 count, which on this auction isn't that unreasonble... give S a bare minimum 2♦ and N a yarb. Even opposite a human bidder your 3N bid is about 4 kings light. I would consider it a bug if GIB _didn't_ slam here. It has 5 more HCP and 2 more spades than promised.

Opener doesn't just go jumping around for no reason. 1c-1h-1s-2s is much easier than 1c-2c-2s-3s and also reveals less about dummys hand. Uncontested auctions aren't as common as they used to be, either. We're much better off after 1c-(p)-1h-(3s) than after 1c-(p)-1h(5+)-3s. Knowing responder is limited really helps opener not do something foolish - and conversely knowning that responder is 12+ will make it easier to find competitive slams.

Having played them extensively, I've ultimately decided that the classical Precision asking bids are just a big loser. You gain marginal utility of infrequent slam hands, but are worse off whenever you end up in only game, which is most of the time. I've become a big fan of the Meckwill Lite structure, which there have been a couple of books written about recently. A few different variants, but the core idea is that as an unpassed responder 1♥ is all (or virtually all) 8-11 hands, and then 1S+ show 12+ hands. Continuations are typically natural. This has two main advantages - the delineation in strength is in and of itself quite useful, and on the most common hand types, opener, rather than responder, is the one showing shape, which is more useful and harder for the opponents to interfere with.

It's bad club player standard, but I don't think it's good bridge.

From the ACBL alert chart, under not alertable, "Any 2♦ response to a strong artificial 2♣ opening"

Because it puts the guess on the opponents, and it means you don't score up 170. I expect 4♥ to have at least play opposite most random hands partner has.

99.999% west for not making a perfectly normal 4♥ opening. Over that E has a much easier time identifying that we have control issues. Even more so if Namyats is on the card. If this isn't a 4♥ opening, what is?

Textbook 3♠ bid.

An easy improvement is available here: 3♣ = Any 5 bagger, now 3♦ is a range ask: 3♥ = min, 3♠ = med 3NT = max 3♦ = 6, minimum 3♥ = 6, med 3♠ = 6, max 3NT = 6, AKQxxx

You should be opening all balanced 14s and some balanced 13s 1NT playing with GIB, because GIB bids so much better on those sequences.

Maybe both saw that they had missed grand and thus played for a Jxxx trump split, and hooked the 10.

As the saying goes, if you smell crap everywhere you go, maybe check the bottom of your shoes.

GIB essentially does not play penalty doubles. If you have made a takeout double at any point in the auction later doubles are NEVER, EVER EVER penalty to GIB.

Any time you accept an invite with a minimum you have to be prepared to go down. This isn't to defend GIB, which is horrible, but as problems with GIB goes I'm having a hard time drumming up much sympathy over this one.

Playing with the robots, as a newer player, will harm your game. They don't play like real bridge players.

Complaining about double dummy analysis being "unrealistic" is like complaining that 2+2=4. It is what it is, by definition.

That is truly a bizarre treatment. The closest thing to standard here is that 2NT-3♠ is a relay to 3NT with some sort of minor-suited slam hand.

I would start by making an accurate description of my hand and opening 2NT (Or even 2!C-2x-2NT)

3♠ does NOT, repeat NOT, promise any extras. It's a mandatory shape showing bid. I'd continue with a cue of 4♦, which doesn't promise extras either, although it would hint that partners splinter wasn't bad news. (Unlike a hand were you held something like ♠ KQJ where you have a lot of points tied up in a suit that isn't very helpful).

What'd south do? At least here in ACBL-land the most common defense to 2♣ - (banana) is: Pass = GF, X=Bust So how is S's pass taking advantage of UI? It's the 100% clear systemic bid.

I'd rebid 5♦ and not 4. Shows a hand with 0 quick tricks, with a great fit. Perfect picture bid. 4♦ would invite a cuebidding sequence.

Rebid 3♦ rather than 3♥. Show 4 more cards in your hand, not just 1, especially with the ♥ not being great for play opposite shortness.
