spotlight7 Posted June 11, 2020 Report Share Posted June 11, 2020 Can anyone tell me what went wrong here? https://tinyurl.com/yarao9pn You were lucky and stayed out of a non making five club game. A nice plus vs 2HXed. Partner should not have passed, however, sometimes bad decisions turn into a good result. 1 Quote Link to comment Share on other sites More sharing options...
DrFell Posted June 11, 2020 Author Report Share Posted June 11, 2020 How do you propose I should beat 2H? And I don't understand why we would be at risk of playing 5C. I think we should play 2S or 3C (unless they bid on in H of course). 1 Quote Link to comment Share on other sites More sharing options...
smerriman Posted June 11, 2020 Report Share Posted June 11, 2020 I think spotlight7 might have been taking a leaf out of johnu's book with sarcasm, given 2♥x is making +2. Basic GIB responds 3♣ - perhaps the advanced bot fluked a set of simulations where passing works out better, but it really just seems like a stuff up on the robot's end.

This was a $0.39 Daylong; I don't know whether they use advanced robots? Quote Link to comment Share on other sites More sharing options...
johnu Posted June 11, 2020 Report Share Posted June 11, 2020 This was a $0.39 Daylong; I don't know whether they use advanced robots?The general rule if you are paying to play (except if you are specifically renting basic robots), you get advanced robots. If it is free, then you get basic robots unless it is a special event. Quote Link to comment Share on other sites More sharing options...
helene_t Posted June 11, 2020 Report Share Posted June 11, 2020 GIB often pass low-level doubles when humans wouldn't. Since their decisions are based on sims, they probably get it right more often than most humans would. This one didn't work but if you never double opps into a making game, you don't double enough.

zhasbeen Posted June 13, 2020 Report Share Posted June 13, 2020 Can anyone tell me what went wrong here? https://tinyurl.com/yarao9pn You got Gibbed. It says support double, right there in the definition. A good question about advanced robots. I don't know what they use for .39 games but I suspect they are basic. A couple times I rented a robot for .25 to play in pairs games against people. I'm virtually certain they were basic since their declarer play was terrible. The one part of the game that advanced robots are well above average in is declarer play. Quote Link to comment Share on other sites More sharing options...
smerriman Posted June 13, 2020 Report Share Posted June 13, 2020 While it's hard to know the exact simulations GIB uses (eg it wouldn't bid 2♥ with *every* single hand that matches the description above), I've done a few rough simulations and 2♥x goes down a surprisingly large proportion of the time. So even though it seems insane to humans, and may well still be insane, I'm no longer too surprised that a limited set of simulations could well tell GIB to pass. 1 Quote Link to comment Share on other sites More sharing options...
