Zenith Daylong Robots

[shyams]

I don't play the above tournament all the time so I might be completely wrong here.

 

My hunch is that the advanced Robots on Zenith Daylong have a slightly different take on bidding and cardplay --- especially bidding.

 

a. Have any of the other frequent players noticed anything unusual about these bots?

b. Can anyone from BBO shed light on this? Perhaps their sampling size is different even if the code isn't?

 

Any inputs appreciated.

They are advanced robots. In free games and robot subs we use basic robots.

 

All daylongs have same robots, adv for the pay games, basic for the free ones. So whatever the Zenith uses will be identical in say ACBL Daylongs.

 

Daylong and challenge robots also run on different machines than robots that are rented, but the program is the same.

 

I can't think of other differences.

 

What have you noticed different?

Thank you, Diana.

 

I don't have any concrete examples to quote; I will aim to make a note of anything going forward.

A friend sent me a hand that he played in the last Forum tourney that made 4S-1 (for 73.7%) we both bid it differently but when I put the hand on the teaching table after rejoining Prime, the Prime robots bid it completely differently.

If the Forum robots are advanced, does that mean that the Prime GIB is not?

[hv=pc=n&s=skhat3dak9874c542&d=n&v=0&b=1&a=1sp2dp2sp3dp3sp4sppp]133|200|

As bid by my friend - he was so impressed by Norths (3X) rebiddable spades he bid 4 - and made 4S-1[/hv]

 

[hv=pc=n&s=skhat3dak9874c542&d=n&v=0&b=1&a=1sp2dp2sp3dp3nppp]133|200|

Here's what happened when I put a robot in the South seat. (http://bit.ly/RobotForum4S) [/hv]

 

[hv=pc=n&s=skhat3dak9874c542&d=n&v=0&b=1&a=1sp3ntp4sppp]133|200|

Here's what happened to me.[/hv]

It's an impressive traveller. someone made 6S-1, 6 people made 4S (after the same bidding made by my friend) and a few clever people stopped after North bid 2S.

A few people made 3NT - and made - pretty good since DD it only makes 1NT.

Interesting hand since despite having a combined 25HCP, no game is available.

Here is an example from yesterday's Zenith tournament:

https://tinyurl.com/yfaytcoy

 

Let us ignore my (South's) silly jump to 4♠. While it may affect the choice of opening leads, there should be no impact once the South hand is exposed as dummy.

 

After the first 8 tricks have been played, the situation is (North to lead):

[hv=pc=n&s=shk52dact&w=shqjtdcj7&n=s7ha963dc&e=sh74dt2cq]399|300[/hv]

 

When I led the ♠7 from the North hand, East GIB knows the exact layout in both minors and can guess the possible layouts in hearts. Here, East chose to discard the ♣Q --- which, IMO, is completely illogical. I also don't recall encountering such an error in other adv. robot tournaments (e.g. Robot Rebate 55%)

 

The robot's play can be right (in the sense of equivalent to any red suit discard) only if its sampling set shows all hands where North holds ♥AQxx or ♥AJxx --- which double dummy assures 13 tricks. In all other situations, the club discard is the only way to allow declarer to score a 3rd overtrick.

 

This foolish discard enabled me to score 76% on the board instead of the 42% that I deserved for my bidding atrocity.

I often bid this way in Best hand tournaments where I know that I have the most HCP points.

In FTF bridge, if I don't think that we're going further - say after competition - I apply the 'rule of 13' viz., if HCP+trumps is >= 13 bid 4 in partners opening of 1 major.

The problem with the Zenith and non-competitive auctions is that partner could have a big hand.

This one is a good example. Slightly better, and it should be in slam.

GIB thinks you are bidding on the LoTT with long spades and little else.

After the ♣K is led 12 tricks are cold.

In the endgame that you show it makes no difference what is discarded. East knows the club holding and the cards are all the same as far as it's concerned.

Or are you making a different point?

Interesting.

 

Same hand replayed with adv robots at a teaching table: https://tinyurl.com/yh2re57k

 

We'll check what was different for the daylong robots.

Or are you making a different point?

 

Yes, I am. The discard of the club Queen at that critical juncture allows me to squeeze West and score the 13th trick. 4♠ +2 scored 42%, 4♠+3 scored 76%

Good defense by GIB East to keep the 2 long diamonds to avoid the potential endplays and maintain safe exit cards. Declarer was afraid to try an endplay which shows what a good strategy it was.

Isn't this the same point that I have been trying to make (for months)?

Take a hand bid and played in any Daylong (advanced robots).

Enter the Prime area and set up a teaching table (also supposed to be advanced robots) and the bidding/play is often different.

Not randomly different (suggesting a feature in the program) but consistently different (suggesting two different versions of the software).

This discrepancy makes a mockery of the scoring in the Prime Club which is meant to be an Area where you are playing with Advanced GIB.

You might be playing with Prime GIB but half the field are playing with sub-Prime GIB.

When I take a hand played by advanced robots in Prime and then try to work out what I did wrong using the robots on the teaching table in Prime they commonly do things completely (and consistently) differently.

I tried this hand on a few settings of my old DOS GIB program that I have tinkered with for many years ...I am not getting past 4S but I am getting some indication that GIB is considering a move forward

All output of my settings is posted above with no edits

 

This DOS program comes with the commercial GIB which Matt Ginsberg gave me for free back in the day or last century

There is also a crippled version which came along with the old Windows client BBO but it did not have all the switches

 

 

Thanks

OK, here is another example - a seemingly innocuous one. I post it here because something is not right about West's first action. Board 5 from my set of yesterday (link here).

 

West holds ♠-- ♥76 ♦AKQ9743 ♣A542. North as dealer opens 1♠, partner passes, South raises to 2♠. What should West do?

 

I am relying on my hunch and my past experience with advanced Robots to say that an advanced robot would bid 3♦. The Zenith robot chose to double with the West hand!

 

I found it so strange that I was planning to post here immediately (i.e. before I played Board 6) but then I decided to wait for everyone to finish.
