"Human Best Hand" Distorts the Bidding Too Much
cloa513 replied to iandayre's topic in GIB Robot Discussion
No you can't. K♦,A♦,heart ruff, A♣- 3 spades makes and that's all. -
GIB takes the forcing part of non-forcing seriously even if it puts into the silliest bid choice. It also has many forcing descriptions written in an invisible non-readable font. That's the answer that we have had over and over and its still broken. How fundamental is its to have coding for forcing and non-forcing bids- it should have been in GIB Version 1- obviously Ginsberg couldn't programme at all. They have to do a serious investigation not just put a crappy patch in the next version. The best answer probably would be GIB is too broken- instead we will take up the offer for Bridge Baron 13 bots to be licensed for BBO.

"Human Best Hand" Distorts the Bidding Too Much
cloa513 replied to iandayre's topic in GIB Robot Discussion
I don't get you with this hand- by all rights South should just bid 4S- its only down because West is void in hearts and East has an easy entry give West AKXXXX and then a singleton heart and the hand plays better - nothing to do with South having the best hand in terms of HCP- don't get hang up about HCP- it should not a be all end all for human bidders- it may be for GIB's bidding ability. -
Really you'd risk moving from a good escape to a bad major hand. Its crappelliti.
-
The bidding is a bit optomistic but the limited definition of 3♦ is a problem- it should say 3 NT+ forcing i.e. can subside in 4♦ or 4♣ so 3♠ is straight out forcing. It really needs to have 6 spades (Dutch Texas Transfers should be extremely defined or expunged from GIB's conventions whereby 4D and 4H response to opening 1NT transfer to the next major) to continue- its hoping for either a good finesse in diamonds or some other extra tricks in other suits and good spades. North is a really powerful slam going hand- bidding 3S with south's hand is a better idea to allow North to describe his hand better- save 4S for even worse.
-
If opponents were doing preemptive raises (as they are meant to for GIB's system) and its nonvulnerable against vulnerable, then absolutely.
-
You have supposed to have five spade- read the bid description- therefore East has no spades- no problem with shape now.
-
How about void of diamonds, A of clubs and 6 good spades KQJxxx, J of hearts- I assume that's enough for GIB to open.
-
North has way more it should have over your bidding sequence. Its more annoying that West passes the second time- its a clear cut 3♠. The failure in play is all your own fault- clear cut to lead spades and keep leading them.
-
Its not such a terrible double- its assumed you were following its standard- pre-emptive raise to game. Your strong standard triple raise is at strong risk of missing a slam. If your bidding like it then East is guaranteed to void in spades.
-
I offered you the chance to poll your views and you rejected- stop whining. Anyway can a freely passed hand contain 15 TP.
-
You are allowed to take out a penalty double

Its mental bidding 3♥ with that- it should be for 10+HCP and 4+♦. This is a simple 5♦ or 4♥ cue. -
I don't think 5 diamond is stoppable. As usual terrible bidding choices and bidding logic available to GIB- so it has no hope of coming to good place but 4 hearts is a bad choice (I think its really meant to show 5 hearts and 6 diamonds despite the lying abysmal bid description- its not what GIB actually thinks) since North would hopefully have chosen double with 4 hearts and 4+ clubs.

Here is my thought on double handling for one level bids. 1. The minimum to double is 10-12 HCP with a four card spade and/or 4 card heart suit as appropriate with 11 TP, can bid with 3 of other major with more HCP and of course strong has no limits on suit holding. 2. Responder bids cheapest major bid with 4 and up to 8 HCP, bidding a jump with 8-10 and bids a minor with up to 10 HCP and with no available 4 card major suit and no cover for openers suit and 4/5 cards or even 3 of a minor bid 2 of minor preferring 1S with three cards in spades. With one cover and 8-10 HCP, bid 1NT, with double cover and less than 5 cards of a minor bid 2 NT and with a five card minor and two covers bid 3NT. 3. Responder with 10+ HCP and at preferably at least 4 of the other major or 4/3 of majors, he cues the suit. 3.1 opener bids the cheapest 4 card major with the minimum hand which can be passed. 3.2 opener bids a 4+card minor with 12-14 HCP still possible to have 4 of the major- usually can't have have both free majors see below- cueing again with 22+8421 points and 444 in other suits. 3.3 opener bids 2NT with a half cover or one full cover. 3.4 opener cues the suit with a strong hand and no half cover unless he has a long suit in a major in which can bids that. 3.5 opener cue the suit at the four level with 444 in other suits or more distributional and 19-21 in 8421 points ace=8,king=3,queen=2,jack=1. Is that clear enough? Should be clear enough for GIB to handle- he can simulate to choose the level at a high level.
-
stop in ♣ is an excessive requirement- remove that one. Why not just double but I suppose that's complicated to programme in- showing likely 4 of that major with 10+HCP.
-
All the crap programming on display. West pass of double is ridiculous. North's 1♠ bid especially with its useless definition. Its pass of a strong raise with its idiotic definition.
-
I don't agree with double then bid your suit with your hand-likely to end in a difficult position even if the system allowed you could to bid it naturally. One- games is not likely with a range of 5 HCP hand in North that he passes. Two- penalty pass is unlikely.

Though it did keep you out of a making 6♥ made by South- how you bid to it is probably impossible. If it was green rather orange then it would be a goodish bid.
-
Its not a bad game- it just happened to have all the bad breaks- two less bad ones and the game is OK.
-
I assume the hand is just to demonstrate the poor state of GIB bidding and bidding explanations but you have to admit that even with North holding 8-10 HCP then South is nowhere near strong enough to bid game. North's hand is just a simple pass.
-
Probably comes from a hidden definition of the first double- must include 2 of every suit to double 1NT.
-
Given the North can't hold 4 hearts or 4 spades and make double penalty anyway then your best best is pass.
-
Only relevant to the bidding choices not the descriptions- their descriptions are sometimes too restrictive/unrepresentative.
-
Except the hand can be unbalanced and then the ranges aren't so limited e.g short clubs.
