Actually since v23 it was reduced to 11+TP for all new suits introduced on level 2. It used to be only for lower suits than opened suit before. If level is 3, points requires are 14+. Since v25, level 3 is reduced so it needs 13+TP for new suit. Level 2 is still 11+TP. Here there was another reason not to bid regular 2♥ bid. Fixed for next version(v26). Following the bidding in displayed hand, over your expected 3♦ reply on 2♥, GIB would bid 3NT after.

Sorry for the inconvenience and the impression you've got based on that inconsistency. Fixed in next version when GIB used to mislead sometimes in raises after two-suits overcalls.

If was 2NT, retransfer had a bug.

3♣ - !Superaccept; doubleton; support -- 2 ♣; 2-5 ♦; 4-5 ♥; 2-5 ♠; 17 HCP; 18- total points Actually, you're expected to use 3♦ as retransfer, then pass or raise to 4 in the major if game was your intention. 4♦ pass here is bug of course, but due no real definition. It will be addressed for change/improvement/definition, which could be either high retransfer or splinter in example or something other as well.

Fixed for v26. 3♣ here means: Invitational with support -- 4+ ♣; 4+ ♠; 10-12 total points

Thanks for reporting. Fixed for next version(v26).

Changed to match same as without intervention. Uncontested, 1♥ - 1♠ 4♦ - !Splinter -- 1- ♦; 5+ ♥; 4+ ♠; 21- HCP; 19-22 total points

Thanks for reporting. It was fixed in current version. 4♦/4♥ after 2NT and supper accept are explained as retransfer. Here now 4♥ shows - !Retransfer -- 5+ ♠

Double of 1NT says 4+♥. So 2♥ call here is taken by GIB as GF with spades and diamonds support. 2♥ - -- 4+ ♦; 4+ ♠; 13+ total points; forcing to 3N

Thanks for reporting. It was fixed in v25(current at the moment). It was caused by a bug, crossing invite of 2NT opening with 2N/3N rebid(after 2♣) as here.

That's the plan of the change, but anyway at the moment based on the 10+TP 3minor over 2NT is still GF (for current version of GIB). GIB wont likely pass this. So after 3minor South-human could decide to pass, but South-GIB(supposedly North-GIB opener 1NT) would continue to 3NT.

Thanks. Fixed.

1Major - 3Major(uncontested) - 4+fit and 10-12TP, could be passed hand as also fits 10-12TP. With 3 cards and 10-12 GIB goes through 1NT expecting to jump after, showing it. If contested, 3Major could vary.

Thanks for reporting this. Several changes done according to this. Tweaked 2N/3N explanations so 2N showing min, 3N showing max. GIB will recognize ( but won't bid of course itself ) 4N/5N jumps over 2♠ or 5N jump after 4♠. They will be just maxes + stopper after cuebid in Splinter major. Also fixed underlying bug where 4N over 2♠ used to be blackwood(♠).

3♠ needs good spades and 10+TP. GIB has the TP, but spades are bad. 1NT 2♥/2♠ Double is 9HCP, higher continuation is 10+TP so adjusted here Double to be also 10+TP and at least 9HCP, as that's the min of invite or to pass partner's suit on level 3. That applies for all 1N 3x cases. So with the hand in the example North would pass.

5♥-> -- 2-5 ♣; 2-5 ♦; 5- ♥; 2-5 ♠; 20-21 HCP; biddable ♥ Book bid on 5♥ is actually pass - to play with 3-4 cards fit in invitee's hand. 5NT seems like escape plan for misclicks, but are we sure it's misclick? GIB would proceed with 6NT or Pass after such 4NT invite, so simulation led to 6N here. Supposedly there are just two answers on 4NT. If 5♣/♦/♥/♠ are additional invites or aces answers you might go down even with all aces in hand. 5NT wasn't really defined, but added just in case when fit seems impossible like in the example if player picked 5♠. GIB would return to 5NT.

Thanks for reporting. Limited to 18-TP as otherwise initial call has to be at least Double (or at least for GIB currently). Therefore, 18TP is your max later.

It used to overcross explanations with 1N opening. Fixed so 3N says 5-9HCP ( after 2N opener ). 10-11HCP GIB is supposed to invite for slam (15-16HCP if opener 1N).

It has been edited in v25. Now it says -- 2+ ♥; 11- HCP; 12- total points

Thanks for reporting. It's fixed (v26), so it will carry the meaning. 1N - -- 9+ HCP; 12- total points; stop in ♥; stop in ♠

Removed 4TP requirement as could be done with flat hand. Applied in the new Jan version (v25).

Supposedly improved in new version. Would pass ( after simulation, as book bid is even 4♦ Law 10 trumps ) rarely.

Not happy, it will be fixed to when opener rebids his minor to be 5+, but i was telling GIB would compete even with 4+. But hopefully it won't have that chance to wonder next version as should be 5+.

Book bid is 5♣, but Double comes after simulation. It will be investigated, although not very clear situation with 6th minor and almost balanced hand. Partner could expect with ♦Axx/Kxx and get 800 where 5♣ to be passed out for 600 or luckily 620 with void diamond leader. Anyway it be addressed for more closer hand to expectation of double.

Even now, knowing you shown only 4+ it would compete with 3♣, but it needs 8TP. Has 7TP now.
