In game #4047, hand 4, the bidding went Gib 1D - P - 2H strong with 6 and 17+ pts. Gib rebid 3D and I bid 4C which was explained as a splinter with D support. Gib simply jumped to 5D which to me is a sign-off with no interest in slam. Why couldn't he bid RKC since he did have the A of Clubs, my splinter. We missed 7. Am I supposed to guess whether to bid slam or not? At best we would be in 6D. I would have to assume Gib did not have the A of Cs.
Another problem was hand#6. Gib was in 3NT making 9 tricks when he was cold for 11 tricks. With a H lead he had 6Ds, 4Hs and the A of Cs. I realize he plays the same with all partners but that is really bad bridge. Can't Gib be programmed to take all his tricks. He does it all the time.

This is a recurring issue; in a game-forcing situation GIB sometimes (I can't figure out when) thinks jumping to 5m shows extras whereas bidding 4m would have been a minimum.

This is somewhat bogus. After seeing the 4-2 heart split, GIB played for diamonds to be 3-1 instead of 2-2. No, GIB doesn't handle his transportation very well, but it's not clear that it's right to cash 6 diamonds.

GIB seems to make splinter bids, and understand splinter bids in the essence that it shows shortness, so it won't leave you in the splinter and takes you back to the trump suit. But it doesn't seem to consistently evaluate its hands well opposite the spl to see how much they get better or worse. Does the eval engine assume *small* stiff opposite, not honor? Do the database definitions of the cue bids adjust to cue on minimum hands without wastage in the splinter suit? I think not.
Also, I once splinter 1d-3h, GIB decides QJ tight of hearts is a stopper for 3nt!
This is driving me a little nuts, GIB often thinks 5m is 20/22+ total points or something, even after it has shown strength by opening bidding or making invitational cue raise or something and limited its hand, then it wants to bid slam if I bid 5m. I want 5m if m are trumps to bar GIB from bidding again if its hand has already limited itself, no more simulations w/o extras! Though I encounter it more on auctions different from this hand, where the diamond bidder is still unlimited.
As for the 3nt play problem, I'd say time controls are too fast; my home GIB plays it beautifully, taking losing diamond hook first as it should to protect against spade attack, but *without* cashing DA, and also *without* cashing all the hearts. If this was a tourney, I thought tourney bots were supposed to be the "advanced" bots and handle this board OK? Or are they set so fast that Gibson kicks in even later than on home version GIB?
