The defensive "skills" of the inept GIBBO robots are on display here.

First, instead of making a NORMAL heart lead, East does what the GIBBO robots stupidly LOVE to do: he leads an ENEMY suit, in this case diamonds.

Second, even if he is GOING to lead a diamond (which is stupid to begin with), he would be better off leading the 5 (since they play fourth best) than SQUANDERING the 10 (and giving declarer a ROAD MAP of how to play the diamond suit). Did the clown in the East actually think he was leading from a USEFUL sequence (109 EMPTY fifth!) in an ENEMY suit? It was easy for declarer to cover with the jack, forcing West's queen, which North won with the king...and later lead low to dummy's 8, successfully hooking the 9 - all thanks to the ineffably STUPID lead.

Third: After East wins his club ace, he cashes the spade ace. His partner West follows with what East can see is his LOWEST spade (the 5). Does East therefore shift to a heart? Of COURSE he doesn't, because HE is a...GIBBO robot...and they either don't signal or they IGNORE signals. Consequently, the hopeless "defenders" NEVER got the heart trick to which they were entitled. Why not? Because not only did they FAIL to cash it, but with their spade plays they established a spade trick for declarer to PITCH his losing heart on.

As is so often the case, their "defence" was an unmitigated disaster...possibly because they are clueless at bridge.

The definition of 3H begins with the ridiculous words "Correct back". Had North bid TWO hearts rather than THREE hearts, these words would have been useless, unnecessary, annoying, and insulting just like (sadly!) many (TOO many!) GIB definitions.

Since he actually bid THREE hearts, however, the words are also incorrect, because the bid is not a "correct back" - it is a JUMP PREFERENCE...an invitational bid showing three hearts.

This hand has an unlucky layout for the GIBBO robot DECLARING 3D, so he can't make the hand and has to go down one.

BUT...being a GIBBO robot, the "declarer" found a way to go down TWO.

Playing with GIBBO robots, I often wonder: Does A.I. stand for artificial intelligence or artificial ignorance?

[benellis58]

Here's a good example of the bidding "judgment" of the astonishingly clueless GIBBO robots.

Everyone is vul. West deals and opens 1S. North, the "HERO" of this post, has KJ1073, 872, Q7, 1096, and passes. East bids a forcing 1NT. South bids 2H.

West passes. Our "HERO", North, passes. East bids 2S. South passes.

West passes. Our "HERO", North is in the passout seat...but why would this "HERO" ever want to defend with "only" KJ1073 in spades...BEHIND the person who OPENED 1S? Why indeed? ESPECIALLY when he has such a truly MAGNIFICENT hand in support of hearts...at the THREE level.

I.D.I.O.T.!

Regarding post #904 immediately above: You know, for some strange reason, I'm beginning to think the "I" stands for the SECOND possibility, not the first.

GIBBO robot "logic": West can't bid FOUR spades over South's 4H (why NOT?), but when East doubles, West now majestically leaps to SIX spades.

Lead diamonds but don't EVER continue them, GIBBO. Oh no, it would be TERRIBLE to continue a suit...well, at least in the BIZARRO WORLD you seem to live in.

A fellow BBO player sent me the hand linked below and gave me permission to post it. He wrote: "5C not 5D. I make it for 68% but I should have made 6 for 99%."

I am pleased that I was sent this hand because it is an excellent example of how astoundingly bad the GIB definitions and the GIBBO robots are. They both rot!

Due to the 3-3 heart break and the onside king of clubs, both 7NT and 7D are ice cold for North-South, but realistically speaking North-South (not having seen all the cards) would want to be in the excellent contract of 6D, where they would happen to make an overtrick. I think the human's bidding was fine, so if fault is to be laid for not reaching 6D, it is ALL due to the robot. No surprise there!

But the atrocity goes much further than not reaching 6D. Thanks to the total cluelessness of the GIBBO robot in the North, the final contract was (only) at the five level...but in...CLUBS! Let's examine the monumental stupidity that led to this joke of a contract in a 4-2 fit.

Look at the stupid, incorrect GIB definition of South's 4C: "5+ clubs; 4+ diamonds...". With EQUAL length in the minors, with four or more (i.e: 4-4, 5-5, or 6-6), the GIBBO robots always open 1D. (With 3-3 they open 1C.) But with UNEQUAL minor suit length of at least four, they always open the LONGER minor. Thus, on this auction where the human South opened 1D and later bid 4C, he COULD have had EQUAL length in the minors...or he could have had longer DIAMONDS (as in practice he did), but he could NOT have had longer clubs. Thus, when GIB states that South has "5+ clubs" but "only" "4+ diamonds", it is completely WRONG. It would be better to have NO definition than to have an incorrect piece of GRABAGE such as this.

Next we see how completely stupid the GIBBO robots are when North, over South's 4C, bids five...CLUBS! What a complete I.D.I.O.T.! South's has shown either equal length in the minors or longer diamonds than clubs, yet North is contracting for the minor (clubs) that COULD be the shorter one (and in practice IS the shorter one on this random hand). Furthermore, North is making this call - in CLUBS - when he himself has...FOUR (!!!!!) diamonds and ONLY (!!!!!) TWO clubs! I've seen cockroaches with greater intelligence!

And...the M.O.R.O.N.I.C. GIBBO robot isn't even following his own GIB definition, which states: "3+ clubs...". Yet some people STILL say "The GIBBO robots are better than most human players". You know what? I think NOT! This hand offers FURTHER evidence of what I have often said, which is that I have never...ever...seen even a single human player as unutterably incompetent at bridge as the GIBBO robots, and even the WORST human player I ever encountered was better than these incompetent clowns.

To be fair to the GIBBO robot in the North, he IS jammed and in a difficult position, but...3NT??? Gaah!!!! BOTH opponents have bid spades, and the auction shows that they have at LEAST nine spades between them...yet BOZO in the North is bidding 3NT (!!!!!) with his "stopper" of Q5 doubleton!!!

Questionable lead by West immediately creates an otherwise unobtainable diamond winner for South AND sets up a Morton's Fork on West. Neither would actually matter since South has FOUR clubs, but when West ducks the heart, the combination of the free diamond winner and the threat of Morton's Fork allows South to take all 13 tricks.

This is the same hand from post #910 immediately above, but from another table. I am showing it here because it reveals the utter absurdity of something I have long criticized: the absolutely ludicrous 2C system of the GIBBO robots...and in particular the TRULY hopeless way they use a 2NT response to a 2C opener. I have detailed in the past the numerous ways this is blindingly stupid, so I won't give the details again, but you can see for yourselves what an unworkable joke the 2NT response is. Pure GARBAGE.

This thread is about exposing the atrocities of the GIBBO robots. but let's face it: human bridge players also make many mistakes.

But apart from the robots making more mistakes and stupider mistakes, there is a key difference:

When a human makes a mistake, it could be - just like the robots - because he is not good enough to realize the correct bridge bid or play. However, it could also be because he breaks discipline, or because he is tired, feeling unwell, or not paying sufficient attention. None of these are GOOD...but they DO indicate that many of the human's mistakes are caused by NON-bridge factors. A GIBBO robot, however, does NOT ever feel tired, does NOT ever feel unwell, and is ALWAYS paying attention...so the GIBBO robot errors are ALWAYS due to a lack of BRIDGE ABILITY.

I have mentioned a few times that most days I play some "Hearts-Style Challenges" for variety. I play matches of 4 boards in the free "Challenge" section, and on each I bid 7NT at my first opportunity. If doubled, I redouble. Then I try to take as FEW tricks as possible. Down 13 is a perfect result.

These games have no effect on any humans, as I am playing with a robot and against two robots. Absolutely NOTHING is at stake for me or anyone else. It's just for fun.

The GIBBO robots here, as everywhere, are absolutely atrocious. Unbeknownst to them, I am trying to LOSE as many tricks as possible, while they are - as always - trying to WIN as many as possible (although you'd never guess that from their monumentally stupid plays - just like in bridge).

Watch how these flamboyantly ignorant fools play the diamond suit in the first four tricks.

Diamonds are first played at trick two, when I, South, lead my stiff king. West plays a normal 3 from Q63. Trying to LOSE tricks, I call for dummy North's jack from J9742. East wins his ace from A1085. At trick three, he shifts to a low spade, won by West's queen.

At trick four, West's remaining diamonds are the Q6 (and the queen is now high, as the ace and king were both played at trick two). West bizarrely leads the diamond 6. Dummy North has the 9742 remaining. Knowing that the EW "defenders" still have BOTH of the two HIGHEST remaining diamonds (the queen and the 10), I call for dummy North's 9. East, with 1085 remaining, plays his...FIVE!

To be fair, I think that these are not the so-called "advanced" robots, so maybe the so0called (!) "advanced" ones would not be THIS laughingly, HORRENDOUSLY bad...although the so-called "advanced" robots ARE usually horrendously bad anyway!
