GIB Release Notes - updated with each new version

Recommended Posts

Any chance you might program them to actually lead the suit you open when they are on lead?

GIB's playing code contains very few rules, it's almost all done on the basis of simulations based on the bidding.

 

I find that it does often lead my suit, unless it has a holding in another suit that it thinks is better. Unfortunately, it often thinks that leading a doubleton of declarer's first suit is a good lead; it seems to be quite optimistic about being able to get a ruff before declarer can draw trumps.

V22 released Wednesday April 18

 

Main Changes:


  •  
  • A 1NT overcall in sandwich position (eg. 1C-P-1H-1N)) is now natural (15-17) by an unpassed hand, unusual otherwise.
  • GIB will be more eager in making weak 2 Major openings.

Some other Changes:


  •  
  • Tweaked some explanations to improve accuracy.
  • GIB will no longer consider passing in Lebensohl after a new suit bid at 3rd level from partner (i.e. 1N – 2H – 3D – pass – ?).
  • Fixed issue where GIB would cuebid or bid NT with a natural suit, instead of making a natural forcing bid (i.e. 1D - 1S - pass - 3H).
  • 4th seat Double is now ignored and opener's rebid will be interpreted as natural (even if it is in one of the two suits promised by Double). However over a 4th seat sandwich NT, opener's rebid in one of the suits promised by the sandwich NT will be interpreted as a cuebid.
  • Example:
  • 1D – pass – 1H – Double (showing 4+S 4+C). Now 2C shows natural clubs.
  • 1C – pass – 1S – Double (showing 4+H 4+D). Now 2H show natural reverse and strong hand.
  • Pass - 1D – pass – 1S – 1NT (Sandwich NT by passed hand, showing 5+C and 5+H). Now 2C/2H will be cuebid showing 4+S and strong opening hand.
  • Fixed a bug where 2NT was incorrectly used to ask for the second suit after a Michaels cuebid promising both majors is made.
  • GIB's evaluation logic for making a 2C opening bid has been improved for unbalanced hands that cannot be opened 2nt, but are too good for a jump rebid in the opening suit.
  • After a 2NT opening and a transfer, GIB will now show another new suit only if he holds a better hand. Otherwise he will pass or bid 3NT.
  • You can expect GIB to be more consistent as both opener and responder in inverted minor sequences. With stoppers in all unbid suits, GIB will bid NT. With an unbalanced hand, GIB will now bid the closest new unbid suit to indicate a stopper there.
  • After a 2C opening, GIB responder who is able to make a positive response will also show his distribution better. Eg: 2C - 2H - 2S - ? Now GIB responder will bid his 2nd suit if he has one instead of just shooting for slam immediately.
  • GIB will be smarter after an invitational 2NT; he'll either rebid opener’s suit, or accept the invite.
  • Opener's responses after a cuebid showing limit raise have been improved.
  • GIB will now take losers into account when opening preemptive 4M in 1st and 2nd seat.
  • GIB used to rush into 3NT after a Stayman sequence with 8-9 HCP. Newly improved GIB will be smarter about using invitational 2NT first.

It's a little more liberal about the quality of the suit. Since neither the notes nor the CC goes into this level of detail, no changes are needed.

 

Turning GIB rules into an FD card is totally impactical. GIB's rules are based on pattern matching, FD is exact bidding sequences.

GIB's convention card says "normally good 6-card suit" and the systems notes say "Disciplined, with honors in the suit". Are you not able to define "a little more liberal" so that we know what does or does not qualify?

I don't understand this one. Is it opener or responder who bids the invitational 2NT in the sequences you're talking about? Does this mean that you've added "rebid opener's suit" as an option in addition to passing or bidding 3N, or that there are only two choices, neither of which is pass?

Responder's 2NT as invite and therefore how again Responder treats the rebiding one of mentioned suits previously.

 

In example:

 

1 - 1

2 - 2N

3 - to be clear NF and GIB won't simulate over this as trying to guess for "hidden" reserves.

 

etc.

Opener bids its cheapest stopper, regardless of strength. But responder only shows his stopper, or bid 2NT with both suits stopped (as in this case) with enough for game.

 

Georgi, why did you make this require 13+? And the rule for 2 has 13+ HCP in its criteria, and shows "forcing to 3NT", but doesn't show 13+ HCP. Since GIB mostly ignores the "forcing to" part of the specification, saying it's forcing to 3NT doesn't mean much.

Is it not standard to bid 2NT with both suits stopped and not enough for game and to bid 3NT with both suits stopped and enough for game?

That's how I play it. That's why I asked Georgi why he wrote the new rules this way, to require GF strength for both 2{SP] and 2NT.

What will be the difference between

 

1minor - 2NT invite 11-12

 

1minor - 2minor

2something - 2NT invite 11-12

 

Why would you pass through invite with same idea? Just to show 4+ fit in the minor?

Yes. The second auction leaves open the possibility of playing some number of the agreed minor.

GIB upgraded - Version 24

Say hi to GIB version 24, October 16, 2012! Main Changes:

  • GIB is now less eager to play in a 5-2 or 4-3 major game. It will prefer 3NT instead.
  • GIB is now more conservative after the 1N-P-2S (Minor suit stayman) auction.
  • Fourth seat preempts have been "beefed up" - they are now made with 10-12 HCP and appropriate length and suit quality.
  • GIB no longer uses "Help Suit Slam Try". This has been replaced with regular cue bids.
  • GIB now treats partner's new suit responses to a preempt as fully forcing.
  • GIB now uses "third suit forcing" after opener's minor rebid. Eg: 1C-P-1S-P-2C-2D/2H. 2D/2H here would be semi natural (3+), game forcing.

As usual, a bunch of bug fixes and tweaks also go into this release. This upgrade is only for those using the new BBO client (web version). Those of you using the old client for Rental Robots, please upgrade to enjoy the new GIB features immediately - an upgrade package for the old client Rental Robots will take a while more to prepare. All Tournament Robots, however, have been upgraded, whichever version of BBO you use.

 

We hope you enjoy the new improved robot. This is the 4th upgrade for GIB we've pushed out this year, and the 11th in the past 2 years. We will continue to strive for excellence in our robot. Every robot report you send in is read, so please keep sending in those bugs reports and suggestions. To participate in discussions with us, please visit BBO's GIB forum.

 

To play with the GIB, either

  • Rent them at $1/week (Basic Robot) or $1/day (Advanced Robot) or
  • Join a robot tourney or
  • Wait for the 1st of every month where all BBOers get to play with robot free for the day

Given that, "3 of top 5 honors" should be removed from the description.

GIB upgraded - Version 25

GIB sends New Year greetings to all BBOers with a new version - Version 25, released Jan 3 2013, is here! Main Changes:

  • If a seven card trump fit is suspected in the majors, GIB will consider passing more often instead of insisting on a raise.
  • Changed the 1S meaning in 1C-1D-1H-1S - this is now artificial and game forcing. 1C-1D-1H-2S is now game forcing with spades.
  • GIB used to be happy bidding a new suit with a minimum hand after partner jumps over a takeout double. Now it'll only bid a new suit with game forcing values.
  • GIB will be smarter about responding with 5+5+ Majors after partner opens 1NT; Transfer and then showing other major will now be 10+ HCP. If opponents interfere with 2C, GIB will now prioritize using X to stayman with invitational values.
  • A lot of bugs were fixed in this release. No actual insects were harmed.

All robot used in tournaments are always upgraded. This upgrade is only for those using the new BBO client (web version). Those of you using the old client for Rental Robots, please upgrade to enjoy the new GIB features.

 

We hope you enjoy the new improved robot. This is the 1st upgrade for GIB we've pushed out this year, and the 12th since 2011. We will continue to strive for excellence in our robot. Every robot report you send in is read, so please keep sending in those bugs reports and suggestions.

Are we running v.28 yet? Not seen any announcement about it. Some months ago I put in a request that the GIB version number be interrogatable by the user in session, which received some positive feedback from other users but no comment from those in authority. I expect that it is something that should be in the "suggestions for the software" forum rather than robot forum, as it may have less to do with GIB programming than interface stuff.
