Thanks for reporting. I think it's a typo bug caused in v26. Fixed in v28. GIB won't speculate with that double.

Would be addressed, but currently: XX is 17+ and not yet GF if partner is min. bidding in their suit ( promised 4+ ) is 19+ and GF. Bidding minor is natural, just 4+ instead of 3+ with no intervene.

Thanks for reporting. Pulling from partner's suit with fit ( as West did here) to obscure other suit is fixed in next v28.

2♣(or opening cuebid) promises only 3+cards and 10+ points, so it might be good bid to "lie" little partner. Especially for 1♦ overcall where GIB won't move from NT as after promised major fit. GIB would bid 2Major if has any major and it's not that weak. I.e. hand like: Qxxx.Ax.AQxxx.xx would rebid 2♠ over 2♣ and would pass over 3N next round. For the displayed hand, GIB would rebid 2♦ over 2♣ and would pass again over 3N. 2N instead of 2♣ shows balanced hand ( not denying 4th major as shows 2-4 ) and it's 12-14HCP. One over one overcall starts from 8+HCP so it's kind of none-forcing. Partner could raise or pass with adequate points.

Thanks for reporting. Fixed in next version v28. So North ( in this hand ) won't rebid opened major pretending its longer 6+ especially with the weak hand here. Currently 2♥ for GIB is cuebid as West has already showed hearts ( natural length 4+ ). Book bid for GIB is pass with North hand as no good bid ( no minor to bid to proceed ). West has promised 3+ in both minors but 3+ is length which GIB could/would ignore while 4+ and you are reaching level to declare where you would be likely defend if pass. Also after 2♥ partner with 22(45) or worse 1255 will be kind hard, while pass would let partner pick better contract. Or if East decides to run away it would be good for N/S in all cases assuming South doesn't have fit in the opened major. With no double 2♥ comes automatically, but here double should help and change somehow the picture.

Thanks for reporting. Fixed in v28.

Over 2♠, 3♣ could let partner bids something to help you. 3♥ would show something like 3442 or 4♣ would show 3244. Otherwise splintering in partner's suit before knowing some shape might force him to bid 4♥ and to emerge to slam which you don't want to. Especially if he is 3343. Over 4♣ you could bid 4♦ cue, getting 4♥ cue and so on, but with 12-13HCP you need at least king in hearts and queen of spades or certainly ♦A and , otherwise to find partner with nothing in ♠, ♦AK and ♥A might not help that much although good controls as you would face 40% or less slam where you need to resolve clubs and trumps well.

Supposedly should show. Does it happen while watching running play in tourney/table/vugraph or it happens under My Results/ My Table Other table ? If occurs again, please make a screenshot and send us on support@bridgebase.com.

Thanks for reporting. Explanation for lengths fixed along the way for opener in v28.

Thanks for reporting. Fixed in next v28.

Thanks for reporting. Fixed in v28.

Thanks for reporting. What was the auction up to this moment? If the blackwood was over spades then 5♥ for GIB could be ask for queen of trumps and 6♥ to be Queen+♥K? Currently GIB shouldn't consider moving over appointed contract. It's subordinate to 4NT player and would only answer, not move up. The only exception (still currently) is that if the blackwood is over suit X, GIB would pass only on 5,6,7 in that suit X or in 6NT. Otherwise it will move to closest call to correct. Very likely in next version v28 human-player would be allowed to ask GIB in particular suit ( although it might be in contradiction with what GIB expects ) and to select contract in his suit where player has shown already enough cards. I.e. 1♠ - 2♣/2♦ 2♠ - 3♦/3♣ 4NT ( over second minor ) - 5 something 5 something ( ? for queen/king) - 5/6 something 6♠/7♠ which GIB would pass, instead of as currently shift to 7 in the minor ot 7NT.

Thanks for reporting. Followons after 2NT rebid would be revised in v28. For each side.

Thanks for reporting it. Probably some wrongly cached information pulled. Would be investigated about, but meanings put seems to be ok. I.e. 2♥ - Secondary support -- 3-5 C; 2-4 D; 3 H; 2-3 S; 12-13 HCP 2N - No support nor new major -- 3-5 C; 2-4 D; 2 H; 2-3 S; 12-13 HCP

Thanks for reporting. Cuebiding as second round rebid in opponent's overcall and active partner would be revised in next v28. So that bug would have appropriate fix. And better explanation also.

Thanks for reporting. It was rare fluctuation, but caused due not quite correct explanation of 3NT rebid. Showing some 5- in both majors. Fixed in v28. So GIB would stay calm and won't simulate over blurred 4major responses after.

Thanks for reporting. Truly GIB knows you don't have ♣A. But 4♦ shows first control in diamonds ( void as GIB has the Ace), and 19+TP. With 13TP in GIB it's almost 99% slam area with super-fit displayed (10 cards here for sure). Having as minimum not more than ♥AJ and ♠A, nothing in diamonds ( as you claimed 1st control which looks like void), these minimum 19TP should represent something like KJ in clubs. Skipping 4♣ call currently means for GIB you don't have Ace, but doesn't refuse having KQJ in that suit. Very likely cuebidding in approved GF situation would be improved in next version - v28. But meantime GIB would rely on aces and won't deduce it might be singleton.

Thanks for reporting. It will be addressed for improvement of the natural 2M ( part of Cappelletti) overcall and followons by both sides. Currently GIB would bid 3♥ here with lack of certain stopper(xxxx,xxx,Qx Jxx), but with certain stopper + length in OM could be tricky as Double doesn't yet promise 4 cards as fit so 3NT could be the contract to make.

Thanks for reporting. Few tweaks for next v28. 3NT shouldn't be limited to 3 cards in other major. Book bid by responder was 3♥, but according to 3- limit for 2NT simulation probably neglected that call. Anyway now it would be close to below meaning 2♣ - 2♥ 2N - No support -- 2-4 ♣; 2-4 ♦; 1-2 ♥; 2-4 ♠; 22+ HCP; 23+ total points Similar with 2♠ positive reply. Book bid by responder also strengthen, so it won't miss to introduce 5+ 4+ shape and opener strong two could decide how to continue and in which suit. As for the displayed hand, 3H would come by responder 100%.

Thanks for reporting. It will be addressed for review and improvement of each side ( opener and responder ) bids.

Thanks for reporting. Sequences will be addressed for review/polish/improvement. Probably not all would be included in v27, especially those with followons like Minor Stayman cuebids after on level four.

Thanks for reporting it. It's a bug, which seems quite permanently happening in that sequent 1♠-2♥. It's fixed in next v27 coming soon.

TOX as any other rules are not described manually per auction. Used combinations about suit ranks, new suit, passed hands, behavior of opponents and promised lengths by opponents in some suit. In some cases explanations are inherited in some shouldn't be. Just because there is some globalization for automated logic sometimes some sequence even seems simple could be not captured. Not passing TOX(once,twice) was meant it won't pass with lack of trumps. Penalty passes are of course kept. But it won't pass with shapes which are rather inappropriate and partner would disagree with it.

Would be avoided in next v27. Having 5+ spades and fit in hearts with invitational hand would go through 1♠ then 3♥.

Thanks for reporting. Re Board 1. It was something slipped just in auction 1minor - X - p - 1♥- * - 2other minor. Fixed in next (v27). It doesn't happen in cases when partner bids 1♦,1♠ or 1NT. Re Board 2. It's a new sequence where after rebidding opening, new suit is 3+. Although seminatural ( only if used after rebidding minor opening and new suit comes at level 2. Level 3 is 4+), GIB raises with 4 cards. Cuebidding up is not yet described fully, hopefully it will be done in v28. Re board 3. v27 carries some fixes about cases like this. GIB won't be passing TOX over preempts raises directly or doubled again. Similar auctions are: 2♦ - Double - 3♦ - Pass * - Double - * - ? 2♥ - Pass - 3♥ - Double * - ? etc. Just not to be missed your auctions in time, i've copied then here with not-expiring link. Re Board 9: 2♣ doesn't promise 5♦ yet as opener could have 2♠3♥4♦4♣ and its forced to bid. However 3- would be fixed to 2- as 5+ needs 3 cards for fit so opener should deny them.
