A splinter disaster

---

Now for GIB 4♣ is natural, but as it does not deny the 5-card ♥, I really don't get the Pass, but I assume it is because BEN never had been trained with that sequence.

[TwoOneBEN]

Annoying that BEN is not bidding the same each time

---

23 players saw BEN bid the very strange 2♥

---

One lucky player got the more natural 2♠ and scored 100%.

Also worth noting the failure to cover ♠9 at trick 7.

[TwoOneBEN]

Testing two different models from BEN in the wild I noticed this strange situation.

Just to clarify: I am using the Open Source version of BEN as participant in the BEN and Freinds daily, so there are 4 BEN's but one (south) is not controlled by BBO
e

---

Down 1 and a fine score of 64%

---

Using the new bidding model all was the same until trick 6, where BEN suddenly found a much better plan.

Making an overtrick and a score of 1.2%

Please remove the randomness in the BBO-BEN

[TwoOneBEN]

I am not sure anyone still read this thread :-)

But this is interesting, because BEN haven't been trained in the default GIB system

---

Explanation is correct, but BBO-BEN just passed.

And yes, the south hand is not good enough for 4♥, but I will discuss that with the open source version of BEN.

It is refreshing not to have Best Hand deals. Closer to real bridge. Still needs some work though

Interested in playing w Ben in 8 board invite tourney.

Post in the Ben on BBO BBO Forums thread to be added to the tournament

If you are interested in playing with the Open Source version of BEN (Not the BBO version) I might be able to set it up.

As a start feel free to challenge the Robot on BBO (Name is TwoOneBEN). In a challenge you will play 3 GIB-robots, and the compare with your opponent. Then you can get an impression of the strength and especially weaknesses of the robot.

Is this a bidding misunderstanding? https://tinyurl.com/ytepqw8f

Very unlucky hand where ♣A was in the wrong hand. And very unsporting of you to double.

[smerriman]

Auction seems to scream for a low club lead.

(I'm still trying to figure out how I scored more than 50% on this hand, though )

Interesting that 26 times North opened a 4th hand 2♦, and one time the Robot in West did not balance with 3♥

Inconsistent bidding.

South open 1N once, and 1♥ 38 times

As far as I can see we got two different defences but bidding and play was identical up the point

And a couple of days ago, a 1.7% board for me because the defense differed at my table only.

It seems Ben and lorserker have met the same fate as GIB and jdonn

[diana_eva]

Nope, we're still alive and following

[lorserker]

Updated the robot in Ben & Friends.
If you run into oddities, please raise them.

I'm not sure if this is a Ben error or a BBO error, but I'm currently stuck on the first board of the Goulash with Ben Daily.

I've bid to what I assume will be the final contract, but instead of passing out the Ben sitting East hangs. After a bit the table closes with an "An error has occurred...GIB Ask Failed: ERROR(2): Robot Error" message. Reopening the table leads to the same issue.

The goulash game was mis-configured, sorry about that. We removed it and we'll post it again tomorrow.

Thanks for letting us know.

I am excited to try Ben out

[smerriman]

While Ben's improved scores in tournaments when playing with itself are impressive, has any work been put towards Ben playing with a human?

That is, as I believe I touched on in an early page of this thread, the most crucial aspect of a human playing with a robot is that it's consistent and understandable. Given it has learnt everything from neural networks and differs from GIB in some areas, I'm still no closer to figuring out when a bid for Ben means exactly what it does for GIB and when it doesn't, implications from when it leads a particular card (e.g. its choice from AKx), whether it signals, how it will interpret cards I play, etc.

Just a little. The only thing i changed is that Ben will now consistently make the same move in identical situations. Because many people gave the feedback that it should do that.

I will try to do more in the future.
Defensive carding is an area which wasn't addressed at all yet.
Bidding system - it is identical to GIB, but different bids can be made in unclear situations (decisions). Rarely, a sequence can come up where it really doesn't know how to bid and makes up something (there are examples in this thread). I think that in the future Ben will have its own explanations instead of leaning on GIB to explain its bids.

About predictability and consistency I am a bit biased. I like a little randomness, because even when I am playing with my regular partner I am not 100% sure that he has what I think he has and that he would always do the same action. I think it is normal to take some reserve when you play. The robotic consistency which allows you to make inferences which are totally certain, are a bit unappealing to me.

Although I have some starting points how I may optimize Ben for humans, future directions will depend on feedback, because the whole topic is subjective and unclear what exactly the goal is.
