Default bid for North is to raise due Law to 3♣. After likely simulation it decided not to bid it at the moment. East simulated too not to pass but to bid, 2♦ ( promising 6+ ) is not that bad as with promised 6+♥, the level might become not so competive with lousy hand. Anyway, Double from each E and W is penalty, not t/o so E can't use the double here as E already declined the chance to have penalty length in clubs. So both North and East simulated a bit, and North simulated twice , second time pass is likely after devaluate the ♦Kx as it would be in dummy's.

GIB considers supper accepts as the supper accept call shouldn't take the re-transfer call. Retransfer calls are the same sub-transfer call one level up. The supper accepts shows max hand with doubleton somewhere or if you bid NT it shows max 4333 hand with 4 cards in the transferred major. Same applies for 1NT/2NT opening. If GIB does heart transfer using ♦'s call, if player rebid 3♦ is maximum and natural and doubleton in hearts as you didn't accept with minimum nor with 4333 maximum. Main idea is always the transferred major to be played from NT's opener side. Which doesn't left holes in revealing the opener's hand distribution. Bidding 3 in the major shows doubleton in the left suit which can't be bidded naturally ( it's diamonds for heart transfer and hearts for spade transfer ). It doesn't justify of course the 25+TP, it's separate thing which has to be a bug which will be addressed to be fixed.

Actually without 2♣ GIB rebid is 3♥ as invite. 2♣ just triggered a bug, fixed so it will be able to use same call instead of hiding the support.

It passed due bad rule allowed to be used. Fixed so GIB won't pass 5NT, it will bid at least 6 in the suit.

3♠ is the call which match the hand properly. will be fixed to be more accurate when picking the Limit raise after opps overcall.

It will pass.

Explanation seems ok, just GIB used a hole and slipped. Fixed so you could rely on 3 cards , not couple of spades.

Not an easy hand to rebid without to lie a bit, but seems 1NT is less harmful. Supposedly fixed not to pass with similar hands.

It took actually wrong bid. 2NT denies 5card support. It should have bid 3♣ instead of 2NT. It's fixed.

For GIB it's 5+♦ and 13+TP, supposedly having 4th major due the Stayman.

Did you bid like slam invite or like invite for game if GIB was on the max 12TP?

It will be reviewed for fix.

For typical auctions GIB checks what opponent bid and the shown lengths. Vulnerability also matters for its pair, opponents etc. 3♦ is definitely bug. It will be checked for fix.

Book bid is pass, waiting with good length for penalty. Anyway, fixed so won't double with 3 spades as turn out here.

these overcalls after 1NT ( by responder as in the example ) are adjusted in next update. It will be limited to 18 as with any 19+ Double is supposedly to be given. So having this the 2♦ will be 13-18TP and as more you bid, the top will be 18TP. Respectively 3♦ later will mean 16-18, the next 4♦ will be 18TP. Therefore North won't be so ambitious to join.

Although GIB could do mistakes, there is no such thing as penalizing partner for something. Main idea which GIB follows is to help partner to emerge, not to sink. If second looks to happen, it's likely a bug occur, unpredicted rare sequence where GIB simulated incorrectly or another issue but usually GIB will try to give you the best result it thinks it could be achieved. So you could accept that if something is wrong, it wasn't yet amended (some things sooner, some not so soon), but not planned to pull you down.

3rd level openings weren't affected since the last V22. So V21 also opens 3♦ here. However, it will be reviewed if there is a hole allowing weak weak openings.

there was a bug with the explanations. Fixed for new update. It will show now -- 3-5 ♣; 2- ♦; 4 ♥; 3-4 ♠; 12+ total points So based on this, North will consider only 4♥ and won't misbid 4♠.

GIB needs 14T-17TP to bid freely 3♥. It might be not too high requirement, just here they are 13. If the queen of clubs was queen of hearts 3H would be easy coming.

It was a bug. Fixed for next update.

Probably, but 4NT followed by 5♥ won't likely solve hearts losers danger. Could be ♦+♠. 5♣ looks like last try and if player bids 5♥, GIB would be happy to bid 6♥. And over 5♦ could bid 5♠ so still one more chance if opener has ♥+♦ to push once more.

3♥ might be not the supperaccept you wish to show ( doubleton ♦). 2♠ shows same but doubleton ♠ which could be more interesting for the opposite hand.

There was a bug. Fixed now. So this will show invitation 6+ and 10-12TP. Therefore West could consider pass or raise to 4♥.

3NT looks like bug. It will be investigated. As GIB doesn't have chance to use retransfer to stop after supper-accept, could just pass 3♥ here.

It's a bug. It will be fixed.
