I think Argine is better, at least it is maintained :-)

Yes, I think that is the way GIB play it. That is OK with me, but I think the explanation of 2♦, should have had an upper bound on points then.

[hv=d=n&v=0&b=1&a=1hp1sp1np?]133|100[/hv] I thought that GIB was playing New Minor Forcing (https://www.bridgebu...nor_forcing.php) but I clicked on 2♦ and it was explained as: 4+♦. 2-♥, 4+♠, 8+ total points, but being unlimited I assumed it was forcing for at least one round. It was not, so probably there was missing a max on the total points. Only made 13 tricks.

It was showing 5+♥ and 5+♣. Many years ago I learned it was part of Michaels cuebid, but It am probably wrong then.

[hv=pc=n&n=sajh643daqt6cq742&d=e&v=e&b=6&a=1d2n(Michaels%2C%2012%2B%20total%20points)p3c(Preference%2C%203%2Bclubs)]133|200[/hv] I wonder how strong a hand GIB needs to bid other than 3♣ with longer ♣ than ♥. I wouold take my chances in 4♥ any day.

OK, I had never seen those before :-)

On Bridgewinners there is a post with to very strange deals with themes I haven't seen before. https://bridgewinner...make-any-sense/ On the first GIB might have changed his mind and thinking 3N would go less down that 4♠ (And the 3♣ is probably a book bid) And on the second I think it is 4th suit forcing, that is the problem, where priority to show support should be higher than showing a rebiddable suit

At trick 6 the ruffing finesse also is strange, but perhaps more understandable.

Once again I failed to check the meaning of the bidding, and just assumed that GIBs system was consistent [hv=d=w&v=0&b=8&a=pp1s1np2dp2hp3h]133|100[/hv] Now 3♥ is invitational, and I assumed that it must be 6 as 5-cards normally invite with 2N (Seen a lot of times) But GIB invited with 3♥ on this hand [hv=pc=n&n=skq9hj9654dj2ckt3]133|100[/hv] instead of just bidding 3N (either directly or after the transfer) It is also interesting that with the same hand the Bot would transfer and bid 3N if I had opened 1N

Yes, I passed 4N hoping it was right. As ♦K was offside it was 3 down and 3N is only 2 down :-) My opponent played 5♦ making

[hv=pc=n&s=saqha8daqj84caj94&d=n&v=b&b=13&a=pp2cp2d2h?]133|200[/hv] Planning to show the hand as 22-24 balanced I opened 2♣, but 2♥ was annoying, and with a single stopper 2N no longer looked like the right bid, so I passed. What I failed to realize was that Pass here is showing 25+ HCP as the bidding continued [hv=pc=n&s=saqha8daqj84caj94&d=n&v=b&b=13&a=pp2cp2d2hpp3cp?]133|200[/hv] And now I was in trouble as any bid would show 25+ - the explanation to 3♣ was just 4+♣ My opponent solved it by bidding 3♦ over 2♥ When I bid 3♦ over 3♣, GIB jumped to 4NT for aces on this hand [hv=pc=n&s=sj32ht9d9652ckq83]133|100[/hv] I will spare you for the rest :-) I did not find a way to stop in 3N or 5♦ after my pass to 2♥

The Bots even doubled 4♠ and got me in the 2000-club

But I wonder why the Bot did not bid 1N.

[hv=pc=n&s=sahkqj8dkt873c974&d=e&v=b&b=6&a=1hp2cp2hp2np3hp4hpp?]133|200[/hv] Just thinking bridge this looks too be down one, so I doubled. Now in my wildest dreams I could not see how GIB could see this as a T/O-Double, but it did, and bid 4♠. I should have checked the explanation of D before doubling. At the replay my opponent bid 2♦, and GIB went down in 3N

I got this hand [hv=pc=n&s=s6ht3dakqjt5ca863&d=w&v=n&b=12&a=ppp1dp1np?]133|200[/hv] Playing matchpoint. In 4th hand a Pass could be right, but opening 1♦ seems right here. Now 3N looks like a reasonable bid (gamble), but in MP with 15 comparisons, both pass and 2♣ could be right. On the other hand we know that EW have the majors, and at least a 9-card fit in ♠, so passing and letting them into the game seems wrong. I decided to bid 2♣ [hv=pc=n&s=s6ht3dakqjt5ca863&d=w&v=n&b=12&a=ppp1dp1np2cp2dp?]133|200[/hv] Well, again pass could be right, especially as the bots in this sequence probably won't balance, on the other hand 3♦ would show 6+♦, 4+♣ and 16-17 total points. A perfect description of the hand So the bidding continued [hv=pc=n&s=s6ht3dakqjt5ca863&d=w&v=n&b=12&a=ppp1dp1np2cp2dp3dp3np?]133|200[/hv] Having describe my hand perfectly Pass was the only option here

It is always interesting who should ask, but I have a meta-rule, that after 3N followed by some slamgoing bid like 4♥ here, then 4N is no interest. You could play 4♠ as kickback for ♥ and 5♦ as kickback for ♣. If partner has 3♣ the grand is 50-50 assuming we are missing the Queen, but we know he has 8 cards in major and only 5 minor cards. Based on our length in clubs he will have only 2♣ most of the time. Missing a keycard I will just bid the slam. Worst case I will have to find trump Queen. And yes he might still have the perfect hand for a grand with AQ in ♣ and ♥ and ♠K, but that is the cost of playing a natural system.

What surprises me is the discard of a ♣ from declarer at trick 2. With one ♠, 2 red aces the 6 ♣-tricks are ensuring the contract. Not taking the ♥-finesse can probably be explained with some simulation, but I could not find a distribution, where discarding the ♣ was right, not even hunting overtricks

Nope, but Double is not the right bid. Either you can double the first time - GIB define that as penalty (10+ hcp), or you can bid 3N with a ♠-stopper. You could also define double here as T/O In real bridge it is also possible to bid 2♠ at the first round showing limit+ with ♦-support.

And as many other situations, not implemented the right way [hv=pc=n&n=sqt5ht73dkq4ckj64&d=s&v=b&b=7&a=1d2d(Michaels)p3sppd(Penalty)]133|200[/hv] A penalty double on about 0 tricks Just making 11 when I lead the normal trump But I have learned yet another lesson

I think the Book bid should be 3N on this hand :-)

[hv=pc=n&n=st62ha84da62cq872&d=e&v=n&b=5&a=3hdp?]133|200[/hv] Does the bot needs stoppers in all suits to bid 3N here? 4♣ was not a winner.
