Preempts have been redefined to be much more in line with what most bridge players would expect.
After an opening bid, overcall, and cuebid raise by responder (1♠ 2♣ 3♣ P), opener's bids have been given more reasonable definitions.
Support doubles will not be passed for penalty as frequently as before. Responder will rarely pass, and only with a trump stack.
After a 4 level opening bid is doubled, GIB will respond with a cuebid with much better hands.
GIB didn't have a good idea when to bid 2/1 by a passed hand rather than 1NT (P P 1♠ P, 1N on x KQxxxxx x Axxx was the most striking example). Now GIB will make a 2/1 by a passed hand when it's right.
Overcalls in opener's suit by 4th hand will be done with more suitable hands (1♦ P 1♠ 2♦).
GIB sometimes didn't find a negative double with good support for opener's minor (1♣ 1♠ 2♣ despite holding 4 hearts). Now GIB will double first to show the four cards in the other major.
GIB was confused about which major to bid first, when holding both majors, after 1♣ (1♦), such as 1♥ with 5-5 or even 6 spades and 5 hearts. Now GIB will choose whether to double and which major to bid more appropriately.
Other minor fixes and improvements.


Still no mention of any of the most commonly reported play bugs being fixed :(

I would like to commend you guys on the hard work you have done upgrading the bots! I have seen major progress!


The one area that remains quite weak is a structure after we open a strong 2 clubs.

If the bot has a positive (or sometimes, even after a 2 diamonds, waiting bid) its second call will many times be a jump to 6nt!!!



There needs to be improvement here when bot doesn't have a fit for opener's first suit. Example: 2c, 2d , 2s..6nt


Another example: I had a hand that was 0-2-6-5 with something like void, Kx, AKQxxx, AKQxx.

I opened 2 clubs, LHO bid 2 spades and bot jumped to 6nt with a stiff small spade.
Luckily the spades were 6-6, so I only went down 5. In the meantime I was cold for 7 of either minor. (Some people may say I should bid 7 diamonds myself, but I "trusted" partner and didn't know about the Heart ace.)

Please make bot "understand" that bids are forcing after a positive response, and that we are in the "slam zone" and can make natural follow-up bids.



Keep up the great work!!!

Gib doesn't "understand" bidding. It has preprogrammed responses that make it looks like it does. It has some rules, but some our silly like passing when it can't find a bid.
It doesn't understand captaincy where 1 partner is in charge. It gives value to shortness in partners suit and in NT. The list is long.
Sarcasm is a state of mind

I am all FOR upgrading GIB as appropriate.

But if you play in a PAY-mini Tourney with all robots, and your robots GIB-s/w has version 2017-upgrd-2, and the 14 player deals you are compared against all used some much older version, it is extremely unfair. And this is INDEED happening Today!

If you browse recent "Weekly Free Instant Has a Different Version" thread you will see reliable reports of this happening this week in Free Games.

Yes, I know (we know?) for functional timing and such, comparisons have to be made (at times?) with (same) deals played on an earlier occasion. But I read that BBO has announced that in these PAY Tourneys the comparisons would be withy deal played with same GIB s/w version.

WRONG!n
Today in 25cents Pay Mini 8board matchpoint 15 players, 14 times the GIB opened 2H on KJx QT9xxx QT Jx. IN 2nd seat, all Not Vul, after a Pass.

BUT MY ROBOT PASSED!

This led of course to completely different auction and what was a n unjustified disasterous resulting score for me.

Not a good situation, Folks!

More to the above. I got curious, so started checking other boards samePAY Mini Tourney from today.

Auction goes 1N p 3N.

Robot on lead has QTxxx AJx Jx Txx

On one deal the GIB leads a Spade.
On another deal it leads J of D. Same exact 1N - 3N auction.

Huge difference in the result.

Hoe can these tourneys be fair with such goings on? And we pay $

This only happens during the 2 weeks after a new GIB version is released. We need to allow time to build up a collection of tourneys that have been run with the new version, so it continues using tourneys from the previous version as the source for instant tourneys.

I play lots of instant tourneys, so I share your frustration during that fortnight.

There was a small GIB update today. Just minor tweaks, but it catches a fix to this bug.

Man, I was ready to start a thread of my own titled “Is it just me?”
While I’ve always felt that the robot tournaments have far more wild distributions and traps than you’d find in live clubs and tournaments, it seems like they have taken it to another level t this past week or so. To compound my frustration, the bots have been making the worst bids I can remember since I playing my first tournament here in mid-August.

Yesterday, while on a 70% pace I picked up a balanced 15 with two 4-card majors and 3-2 in minors. Bot responded 2C stayman I showed my hearts and bot rebid 2NT. This sequence does not promise a 4-card major since 2NT is a relay to 3C. To make sure I had it right I ran my cursor over the help bubble, and it couldn’t have been clearer: “Invite 2 3NT, no-card major – 3-h, 3-s; 9 hcp”
I passed, and the first thing I saw when dummy came down was J 10 9 6 of spades. I was starting to boil already this was nothing compared to the rest of his hand. He had A Q 10 9 x x of clubs, 2 little hearts, and a stiff diamond.
Still, the sadists that set this hand up were just getting warmed up. The bot sitting east promptly reeled off 6 diamonds and the ace of spaces, to set me 2 tricks.
Interestingly, there were several other players that got into spades, so I looked at the traveler to see how they did it. In most cases they showed their spades at 3 level after bot’s 2NT rebid. Either they had experience with this sequence before or they don’t bother reading those bid-meaning messages that you get when you run cursor over them. The hand made 4 and 5 spades. Meanwhile, it ruined a nice game for me but I wasn’t giving up...that is until board 10.
I guess I have only myself for what happened on this one, board 10, since I’d already been burned for it on 2 counts—I’ve had takeout doubles left in by robot before, and I just got burned reading the help explanation as noted above. The robot had zero defense to leave the double in, btw, but he had J 10 9 5th of diamonds to go with my KQx. The bid meaning was equally clear as the other one, reading: "Takeout double" and the symbols that followed it suggested nothing else.

One more and I’ll stop complaining:
During the last game I played today the north bot opened 1 of minor and I responded 1 heart. Bot rebid 1NT and I raised to 4NT with my balanced 19. However, glutton for punishment that I am, I read that #%^&! help bubble again before I made my call. True to form, it laid down the cutest little 4-3-3-3 twelve pointer you ever saw after taking the invite to 6 in a split second.
Down one for me. You guys all know when bot leads a spade, dummy holds A x x and you hold Q x x. That’s right, you guessed it, but you can only hope for a miracle. There was not a potential 12th trick elsewhere, so I was put out my misery early. Of course he didn’t have the king.

This “bid helper” message they have is a serious problem, and from what I’ve heard it has been happening for a long time. From a competitive standpoint I know it’s the same for everybody, but I’m not as excited as I was even a few weeks ago when I had hopes of seeing some improvement.
At the top of this thread it says:

“GIB Release Notes…A place to keep track of GIB upgrades “
After checking it out I see that the last upgrade was in 2011!!

Also, I don’t see any GIB programmers sticking their heads in here like I was told when I contacted support. It makes me wonder if they even have a staff for this department.

No, the thread was begun in 2011. That first post indicates that Version 19 was installed in October 2011. SMerriman's post from August 2017 links to the most recent announcement, stating that Version 37 was installed.

And BarMar did stick his head in here, two above your post.
