Now as you can see it,we are free to deceive the robot, and don't have to worry about punishment in basic GIB.http://www.bridgebase.com/forums/public/style_emoticons/default/laugh.gif

I see a lot of people opening 1NT with small singletons. Utterly senseless.

I don’t think that you should dismiss the tactic with such scorn.

I believe that you are applying "real world" background conditions to a different environment in which different theoretical market forces are at play.

One of those factors, for example, is that three players at the table will place 100% trust that you will have no singleton or void, and of those three, twice as many are opponents as are on your side.

 

The measure of the senselessness of the tactic is its actual success rate. The prevalence of the practice is a reflection of a high perceived success rate. Perhaps not an entirely accurate perception, but I think a different success rate than that to which you would be accustomed in a human field.

What's with the ♥Q lead though? I could understand if GIB led the ace, but who leads Q from AQx?

[johnu]

The key detail of the hand is "Basic" GIB, and Basic GIBs randomly do inexplicable things. The BBO response has basically been to play in games with advanced robots if you aren't happy with the Basic GIBs since they are what they are, Basic.

The club switch is even more bizarre after South bid clubs in the auction. Even the auction was not a lie, there is no reason not to continue with hearts- South with 2 hearts is probably dead meat.

Indeed, and what's up with east's ♥4? I wonder what that was supposed to mean.

[1eyedjack]

I am just surprised that GIB has taken the trouble to assign a formal definition to the 3C bid

GIB defensive carding woefully inadequate. relies on simulations. why not get help from partner? I think 4♥ shows count, attitude more useful and give ten so p knows is high card

that said switching after Q♥ holds is very bizarre surely you place partner with K♥ even without a signal

[johnu]

Several people have said that GIB gives count. I haven't kept any kind of long term statistics, but my impression is that GIB plays random spot cards. IIRC, GIB doesn't give count if there is some other priority, if so, it does it all the time for no reason I can see. Having seen GIB randomly play 2nd hand high with valuable spot cards for no reason except to insure that declarer won't misplay the suit, I'm not convinced that count happens more than about 1/2 the time (ie random). I think I'll start reviewing a few sessions next year and see whether I'm totally off base about GIB signals.

When I bid at random again,I found GIB make more and more stronger,very good.For example:

GIB started to fight back,defeat me and GIB is no longer any chance for us,I congratulate GIB.

FOUND IN GIB notes system notes

" When it's following to partner's opening lead, it will give an attitude signal:

 

•High spot card with an Ace or King

•High spot card with a Queen behind dummy's Ace or King

•Low in any other situation

 

 

 

 

When it's trying to win the trick in third hand, it will play the lowest of equals. Otherwise, when following suit it gives standard count signals (high = even); an exception is when it's forced to play equivalent cards in a doubleton, it will randomize them because of "restricted choice". "

 

so at lead against suit it tries to give attitude, but from the notes if lead leads from AK GIB doesn't encourage with Q

anyway these notes have not been updated in a while but GIB has been updated multiple times so who knows if they still hold true.

 

maybe gives count in NT if it cant win the trick!?
