Fixed NT rebid in next update.

This should be fixed for next updated and GIB not to miss to double 6N/7N with 2/1 Aces.

It will be investigated for fix. Hopefully it will be part of next update.

Currently that sequence it's not defined for GIB.

Hand 1 - pull out and description of 3NT are fixed in next update.

GIB counts only 8TP as doesn't add TP in ♦.

biddable, rebiddable, twice rebiddable, strong rebiddable, solid, etc are terms usually coming to say this suit has specific quality along the length. otherwise the length will be given directly with X+. But running from 2♦ and explanation of 2♦ will be reviewed for fix.

It's a bug. It will be fixed.

1M-4M will be changed for the next update. Basically, if there is none-jump overcall ( including X as well ), 4M will be preemptive. If there is preemptive overcall, bidding 3M without jump will be something like 7-10, 4M 11-12. So the displayed hand according to this new way, will definitely bid 4M ( 4♥ here ).

5♠ is not forcing. It's not well described in this sequence, but it carries 5- 8421 in the trump. So it's asking for the trump quality to bid 6. If it asks to bid 7, it would use 5NT instead. It will be addressed for improvement in GF and slam sequences.

4♣ wasn't lie. GIB consider HSST just as it was used. With natural honor contained bid. It can't be used with xx or xxx. It requires at least queen in it. Anyway, GIB doesn't have support in HSST of course, but seems couldn't just close to 4♥ with longer trumps and side A and K. However, HSST is about to be removed in the next GIB update. It will be replaced with regular cuebids, showing Aces and afterward kings for the denied Aces suits.

Currently it's 4♥ - Free jump raise -- 3+ ♥; 11- HCP; 11-12 total points ( 11/13 from unpassed hand) But it worth adjusting for the 3♥ - Free jump raise -- 4+ ♥; 8- HCP; 7+ total points

Seems unclear who should step into blackwood first. After GF and such suit-jump, would be also reasonable, ♠ settled for cuebidding and 4♣ to be 1+/2+♠ and A♣, etc. Opener wishers to claim that's our suit, so 4NT from the responder could be too quick. 3♠ might need some more honors in the suit, thou, as you nearly claim you would resist on void in partner to make game in this suit. Book bid for North is 4NT actually.

Right, but South is human. I've seen many players passing with opening hand and then overbid or bidding game. GIB is not able to "reveal" such bluffs and therefore to place 14-15HCP in these hands. Similar here. South is using weak overcalls bids.

The continuations will be addressed. 3♣ is easy to be prevented with West's hand, but it should have more accurate meaning than 4+♣ as in theory it covers some meanings if it's 17-22TP. Bidding one of the both South's suits is 19-22TP, so needs to be improved for sure as both mean some strong hand.

Fixed for next update not to go through bad bids like 2♥, which limits the hand in the lower range.

Probably some issue with the fetch from DB, but the explanations are existing: 2♦ - Aggressive weak jump overcall -- 6+ ♦; 9- HCP; 3+ total points 3♦ - !? -- 9- HCP; strong rebiddable ♦; 11+ total points; 6+ relay points

Fixed in next update. Description is correct, bid isn't.

Thanks for reporting. It will be fixed.

It's fixed for the next update. It was due inappropriate simulation. Explanation will correspond to the hand.

Others 1NT rebids seem fixed. Maybe 1♥-1♠-1N slipped. Fixed in next update to show - -- 2-3 ♣; 2-3 ♦; 5 ♥; 2-3 ♠; 12-14 HCP

I mean that: 1♣ - 2♦ - 2♥ - Free bid -- rebiddable ♥; 11+ total points 1♦ - 3♣ - 3♠ - Free bid -- rebiddable ♠; 14+ total points Since V23 the new suit after overcalls which used to be higher then rebidded opening requires 11+ instead of former 14+. But if the responder first bid is at 3rd level ( with no jump ) 14+ remains as expectation.

It will be addressed in coming or next after update.

It happened due simulation. Fixed for next update not to go in down ranges as did here with 2♦. So GIB has couple of choices, not strictly one NMF. Like NMF or making 3♦ with top invite 12TP range showing two-suits.

Thanks for reporting it. The issue is fixed for the next update. GIB will give the corresponding bid with that hand 2NT - 2-5 ♣; 2-5 ♦; 2-4 ♥; 2-4 ♠; 21-23 HCP; stop in ♣ That's leads in the particular hand to 3NT by West after. Rebid of 1NT is 19-20HCP based on the fact 1NT direct overcall is 15-18HCP.
