From the WBC-1000 Some errors are really strange, and this deal had a few, but also some interesting aspects. You get: [hv=pc=n&s=shakq986daj3caj64&d=s&v=0&b=11&a=1h1s4h4s?]133|200[/hv] What now? 4♥ is a preemptive raise with 4+♥. Human no 1. bid 5♥, and was doubled by west. After the lead ♠T you get this dummy [hv=pc=n&n=sq8hjt5432d876c52]133|100[/hv] It seems you will have to find KQ in either minor in East. You have only 2 entries in dummy, but playing ♣ first creates extra entries, but declarer played a ♣ from hand and went down. In the replay the human had higher ambitions and jumped to 6♥, also doubled, but this time West lead a trump, and focus was on the East bot, that had to find a discard a trick 1 from [hv=pc=n&e=saj7643hdt42ckqt7]133|100[/hv] Discarding a ♠ looks easy for us, but the Bot discard ♣T, and here declarer found the only way to make 6♥.

I played ♥10 to the J, and Wests King. The Bot switched to a ♦ and got a ♣-ruf, One down - nice defense. My opponent played a small ♥ to the Ace and continued ♥, where the bot used ♥K and continued ♥, 10 tricks and 12 IMP out. The play of the cards gives 2 different simulations, but the bot knows the same about the hands in the 2 situations, yet East had one more discard against my opponent, but getting the ruff seems the be best chance to defeat the contract.

After the ♣ lead I played ♥J and mis guessed the ♥s. With ♠s 5-0 there was no way home. But again I was outplayed by my opponent as declarer played a ♠ to the King at trick 2. Unblocked ♦AK, ruffed a ♣, and dropped a ♥ on ♦Q. Now when declarer played ♥J from dummy East flew the ♥A, and declarer had 10 tricks, and I lost 10 Imps. Perhaps it is a good rule to postpone guesses to the latest moment as bots is having trouble finding the best defense, even knowing more about the hands. I will be back for next tournament :-)

Getting a ruff, and finding partners entry in ♦. Now after getting the second ruff even a beginner should be able to count the hand Partner has ♣KQ and ♦AK. Now perhaps partner could have ♥Ace (if 1-3-4-5 and 16 HCP), so we might need to play 2 times ♥ before trying to promote a trump trick, but none of my simulations resulted in playing the ♥7 as the robot did, and gave the contract.

2♦ is the strong hand, I assume the seats are switched to make you declarer. (6♠ was the par contract)

Our hero here bid 1♦, and North bid a fine 2♦. South bid an invitational 2N. But the interesting bid is Norths 3♣, that according to the explanation denies a stopper in ♣, but nothing else as the 2♦ did limit the hand. 3♣ is forcing to 3N, but is the bot searching for a major contract?

Now it is known, that South must have 2 ♦ and a ♠ left, so why discard ♠A?

This will be my last post here about GIB. The level of play is just to low.

At this point West is known to be void in ♥ and void in ♣. There is seen from Easts point 4 missing cards, 2♠, ♣9 (Must be at declarers hand) and ♦J (could be at either hand, but as human we know it is at partner, but ignore that). Playing a small ♠ is just a no win play - I have tried to find a simulation, that could justify the play, but I failed. Was it 2 humans I would have given some blame to West for not throwing ♦J in the 3-card ending.

You are right, I better stop posting. At the todays Zenith daylong (Advanced robots) I saw so many errors, that should be corrected first. Perhaps I will return when Argine goes public, there is at least some developers trying to improve it

You are missing my point. The error is BBO by offering such a bad bot. I understand the different versions, and also understand that BBO (hopefully not intentional) have made the freeware version worse by "improving" the bidding. For me that is a bug - if not a software bug - then a marketing bug. The two deals I have shown are both played with the no-pay BOT, and even in a no-pay version they should bid the same. If I disable simulation on the last board it will pass, but as I wrote it actually bid 5♣ in the free daylong, that as far as I know isn't using the advanced robots - but I might be wrong My error is (still) having the energy to report these kind of errors, errors that basically is destroying the fun for thousands of players. Back in 2019 the last time they released a new version Diana wrote So I expect the effort was made to improve GIB

Well, I hope we can agree it is an error passing on the hand given Then feel free to judge where the error is: In the bidding database Missing simulation BBO offering an bot worse than free GIB released 10 years ago My expectations that the bot is better than a beginner other It is not important where the error is, just someone would fix it :-)

I have reported this before, but did not have the board, where it happened Look at GIB's lead at trick 5 - playing the 9 is just to fool partner [hv=url=https://www.bridgebase.com/tools/handviewer.html?lin=st||pn|Thorvald,~~v3fakebot,~~v3fakebot,~~v3fakebot|md|4SK432HJ4DAKT75CA5,SA8HAKQT63D9C9642,SQT95H87D862CKT73,SJ76H952DQJ43CQJ8|sv|b|rh||ah|Board%2010|mb|P|mb|1N|an|notrump%20opener.%20Could%20have%205M.%20--%202-5%20!C;%202-5%20!D;%202-5%20!H;%202-5%20!S;%2015-17%20HCP;%2018-%20total%20points|mb|3H|an|strong%20rebiddable%20!H;%2014-16%20total%20points|mb|P|mb|P|mb|P|pc|H8|pc|H2|pc|H4|pc|HT|pc|HA|pc|H7|pc|H5|pc|HJ|pc|C4|pc|C7|pc|CQ|pc|CA|pc|S2|pc|S8|pc|SQ|pc|S6|pc|S9|pc|S7|pc|S3|pc|SA|pc|C9|pc|CK|pc|C8|pc|C5|pc|D6|pc|D3|pc|DT|pc|D9|pc|SK|pc|H6|pc|ST|pc|SJ|pc|C6|pc|C3|pc|CJ|pc|D5|pc|D4|pc|DK|pc|H3|pc|D2|pc|C2|pc|CT|pc|H9|pc|D7|pc|DQ|pc|DA|pc|HQ|pc|D8|pc|HK|pc|S5|pc|DJ|pc|S4|]399|300[/hv]

The explanation does match the original hand, so I assume there could be a difference in the explanation and the actual rule for selecting 5♣ Looking at the rules in the free bot there are the following for bidding 5♣ database search: 1S.2N.4S.5C -> 6 -- 5C..4 .S... ..... ..... ...... 1025 (59): ~b==#1~@05~.>24-#0(2,13)~@09+~((h=.)|1)~#g~#28(b)-h>a+e-2~ -- 5C..4 .S... 8.... ..... ...... 1034 (58): ~b==#1&(b)+k>a+e-2+13+#3-#13~ -- 5C..4 .S... ..... ..... ...... 292 (44): ~b==#1~@05~.+#0(2,13)[#17(5),30]~ -- 5C..4 .S... ..... ..... ...... 295 (30): ~b==#1~@05~.+#0(2,13)>=#17(5)~ -- 5C..4 .S... ..... ..... ...... 297 (5): @05~.+#0(2,13)>=#17(5)~@09+~.>6-#0(2,b)~#b -- 5C..4 .S... ..... ..... ...... 296 (4): @05~.+#0(2,13)>=#17(5)~@09+~.>6-#0(2,b)~#b -- 3+ C and the bot will bid 5♣ with both hands, but the BOT at BBO will only bid 5♣ with the last hand

Try giving the bot all 13 ♠, and the rules will make the book bid 4♠ in any position
