https://tinyurl.com/yjkkj2hy robot claims 5c denies heart ace. Yet? So easy not to make this mistake , must be bug.

https://tinyurl.com/yebfx389 It is very very simple. You know a bid is forcing, so you don’t pass.

https://tinyurl.com/yh4krbkh BTW *I* am the hand with clubs, not robot. After 2S, the bidding should be 100% over? What in the world is 3H ? If robot truly had an invitation hand, then should use NMF.

The partner of the robot really thinks it would bid 3C with 4 clubs and 6 spades, so there is very little chance it will take it out of 3SX. I, however, know the robot better in this situation. It would *never ever* bid 3C with this holding. In fact, I would dare say there is no holding whatsoever that this bidding sequence should ever happen. No player would ever bypass a 5 card spade suit at the 2 level, to bid a club suit at the 3 level.

https://tinyurl.com/yguyqw92 Bidding over 2h is questionable, bidding over 3h is of course insane, and description of 3s is wrong. If bidding is to believed then robot will have 6 clubs and 5 spades. I knew it was totally effed so I doubled.

https://tinyurl.com/yeylcrgp Robot is supposed to escape with 5H or 5S once 5D has screwed the pooch?

https://tinyurl.com/y6xvs2v2 MP's One of the free competitive robot individuals This is so amazingly bad as to be considered a bug

Yes I know I could overcome any lead double dummy. However, the lead was impossible for its GIB partner to decipher with any certainty. Some things are simply so easy, why tinker? If I have JT9x, always lead the jack.

I think there is no human alive that would lead a low club in this auction, for exactly what happened.

Knowing gib I would say 2d. 2s also possible with gib along the lines of “bid my best suit”

I would like to add, it was robot that bid 2s, not me. :)

Perhaps utterly deranged. Bbo forums robot tourney. https://tinyurl.com/y9eqd8b7 2s!? Lack of double of 1n!? 2s even more incomprehensible since I am known to not even hold 3s What is the matter with 3D if it feels it simply has to bid?

More Robot tips: Bid game far more aggressively than normal when you hold a long suit. Their insanely passive leads tend to make this a winning action. The robots almost always switch suits. If you let them hold the first trick, they seem to switch about 80% of the time.

Robot tip: Do double their cold 3N, if they have anywhere at all to run. They *will* run.

I knew this. This is why I doubled *them* on the cold 3N

If there is a logical alternative, gib robots seem to Always believe the double. https://www.bridgebase.com/tools/handviewer.html?bbo=y&lin=pn%7Cgoffster%2CRobot%2CRobot%2CRobot%7Cst%7C%7Cmd%7C2SAK98HQ2DQJ83CQJ8%2CSQJ64HK4D954CAT96%2CS7532HJ873D62C732%2CSTHAT965DAKT7CK54%7Csv%7C0%7Cah%7CBoard%208%7Cmb%7CP%7Cmb%7CP%7Cmb%7C1H%7Can%7CMajor%20suit%20opening%20--%205%2B%20%21H%3B%2011-21%20HCP%3B%2012-22%20total%20points%7Cmb%7CD%7Can%7CTakeout%20double%20--%203-5%20%21C%3B%203-5%20%21D%3B%202-%20%21H%3B%203-4%20%21S%3B%2012%2B%20total%20points%7Cmb%7C1S%7Can%7CFree%20bid%3B%20new%20suit%20--%204%2B%20%21S%3B%2011-%20HCP%3B%208-12%20total%20points%7Cmb%7CP%7Cmb%7C2D%7Can%7COpener%20two%20rebid%20--%203-%20%21C%3B%204%2B%20%21D%3B%205%2B%20%21H%3B%202-%20%21S%3B%2011-16%20HCP%3B%2012-18%20total%20points%7Cmb%7CP%7Cmb%7C2N%7Can%7CBalanced%20invite%20--%204-5%20%21S%3B%2010-11%20HCP%3B%2012-%20total%20points%7Cmb%7CP%7Cmb%7C3N%7Can%7C3-%20%21C%3B%204%2B%20%21D%3B%205%2B%20%21H%3B%202-%20%21S%3B%2014-16%20HCP%3B%2018-%20total%20points%7Cmb%7CD%7Can%7C3-5%20%21C%3B%203-5%20%21D%3B%202-%20%21H%3B%203-4%20%21S%3B%2012-20%20total%20points%7Cmb%7C4H%7Can%7C3%2B%20%21H%3B%204-5%20%21S%3B%2010-11%20HCP%3B%2011-12%20total%20points%7Cmb%7CP%7Cmb%7CP%7Cmb%7CP%7Cpc%7CSA%7Cpc%7CS6%7Cpc%7CS2%7Cpc%7CST%7Cpc%7CDQ%7Cpc%7CD4%7Cpc%7CD2%7Cpc%7CDA%7Cpc%7CH5%7Cpc%7CH2%7Cpc%7CHK%7Cpc%7CH3%7Cpc%7CSQ%7Cpc%7CS3%7Cpc%7CD7%7Cpc%7CSK%7Cpc%7CHQ%7Cpc%7CH4%7Cpc%7CH8%7Cpc%7CHA%7Cpc%7CHT%7Cpc%7CD3%7Cpc%7CC6%7Cpc%7CHJ%7Cpc%7CD6%7Cpc%7CDK%7Cpc%7CD8%7Cpc%7CD9%7Cpc%7CH9%7Cpc%7CS8%7Cpc%7CS4%7Cpc%7CH7%7Cpc%7CH6%7Cpc%7CS9%7Cpc%7CD5%7Cpc%7CC2%7Cpc%7CCK%7Cpc%7CC8%7Cpc%7CC9%7Cpc%7CC7%7Cpc%7CC4%7Cpc%7CCJ%7Cpc%7CCA%7Cpc%7CC3%7Cpc%7CSJ%7Cpc%7CS7%7Cpc%7CC5%7Cpc%7CDJ%7Cpc%7CCT%7Cpc%7CS5%7Cpc%7CDT%7Cpc%7CCQ%7C

The proper algorithm would say (at IMPS) "Can I guarantee the contract with no assumptions" and play that way. falling back to "Can I guarantee the contract with assumptions" if it cannot.

This was IMPS

https://tinyurl.com/yyrvs6c7 The 2S bidder will *always* have a strong *distributional* hand. Having 5 diamonds and 4S would be the barest of minimums, and perhaps even then, 6-5 is more likely.

https://tinyurl.com/y6lvlpau Not an advanced robot. It realized I should have had solid 7 card diamond suit. I realize the human's bid was inaccurate, but robot should still have been able to count at least 12 tricks assuming a 7 card suit (4 majors, one club ruff, solid 7 diamonds) Does the non-advanced robot do any sort of random sampling to see whether it should bid more?

I did modify this post with a url. I think it is clear to anyone that this is a bug. This is not about achieving the optimal result. There needs to be some sort of fallback logic in GIB when it is in a 100% forcing situation where it does not pass. i.e. I always rebid any agreed suit. I bid NT. I bid a new suit. I rebid a suit. Anything except pass.
