IMPs, ACBL robot individual
My 6♠ bid denied holding a King outside the ♠ suit. So, looking at ♦Jxxxx, how exactly does the robot think we can avoid a ♦ loser in 7♠? Assuming I hold ♦AQ, the grand will be on a hook at best (if I hold AQ10(x)) and will be a much worse proposition if I hold AQ tight or AQx.

It's really a shame that the GIB forum doesn't have subforums for frequently repeated issues: Cappelletti, RKC, pulling/leaving doubles, inappropriate cuebids, etc. That way, the developers could tackle a group of related reports together which is probably more effective/efficient than handling one report at a time.

Why did Gib even bid 5N? Apparently it doesn't need a King so why not just bid 7♠ over 4N KC response?
Sarcasm is a state of mind

This would fit right in with BBradley's excellent idea. It's well documented over several posts that GIB often bids 5NT for Kings, then does not know what to do with that information. I've seen at least 3 hands where once GIB's partner showed a side K, it could easily count 13 tricks, but it still signed off at 6.

It is not uncommon for 5NT "king ask" bidder to remain in doubt. That is a principle not confined to GIB. In addition to asking for Kings the bid has a consultative function. By confirming that all key cards are held and that there is grand slam interest, partner is invited to bid the grand (with or without showing Kings on the way) if partner can count to 13. Indeed on occasion it could be that virtually no King-showing response would clarify the position and yet 5N is appropriate in case partner can bid 7 based on knowledge that all key cards are held.
If, having bid 5N, the response allows 5N bidder to count to 13 but still declines, as does happen with GIB occasionally, then that is a bug. But the bug is not in bidding 5N.
Given GIB's tendency to leap to slam (sometimes grand) without using Blackwood (or alternative) despite that there is room to enquire, I am nervous about discouraging it from using the tool. Provided of course that it bids to the right level on response.

I agree. I never suggested that GIB stop bidding 5NT, only that it be programmed to use the information gained appropriately.
