NEVER DOUBLE for penalty. Bot will consistently override your double with an impossibly stupid bid.

I'd like an explanation from one of our experts why ROBOT bid a 4 card heart suit 9XXX in response to a double of opponents opening bid of 1 club when holding a five card diamond suit Q10XXX??????? I'm waiting.

Are you saying that each player is given a different set of 4 hands......that my four hands are different from every other player on line? Don't think so.

Done that....70,000+.

The law of averages does not apply in BBO? I am certain that it does.

Then you are also saying that 55,000 individuals played the exact same hands on that same day and 51,000 of them scored better than an average result???? PREPOSTEROUS!

NO, I am not talking about "just play bridge." I am referring to "bridge 4."

There are 4000 reported players. You play 4 hands with results that would be considered average in any duplicate session yet your BBO rank is 51,000. Do you have in incognito table with 51,000 players, or what?

Doubt that you would be quite so cavalier if it was your $40.00. Best wishes

Apparently GIBs do not understand each other or are a victim of their overloaded convention card.....what a revelation!

Let's all be honest. A GIB defensive opening lead is 6 to 5 to lose a trick. This is the one area that for years has screamed for significant change (that never comes). After a routine garbage opening lead Gib's subsequent defensive play improves.

That being said, it obviously didn't work very well.

This cannot be that difficult a fix. Can't speak for others but I am fed up with the insane choice of Bot leads that consistantly cost tricks.

so the short answer is that Bot's defensive opening leads will remain UGH and costing a defensive trick more than 25% of the time that a bid suit is not BOT's chosen opening lead.

The topic of Bot's defensive opening leads has arisen many times yet each new iteration produces the same insane lead selections. When partner has bid during an auction it should be taken as a clue to partnership defensive strength yet is consistently overlooked by Bot. Yes, there are Bot holdings that clearly call for a lead other than partner's suit yet Bot relies on doubleton or singleton first, high card sequence second, a trump lead third, then maybeeeeeeee.....partners suit. I am sick of it!!!!!!!!!

In five years I have never doubled at the two level without partner bot bidding over my double. On the other hand, when playing vs two bots, it is not unusual for opponent bots to pass after a two level double resulting in at least a down two result. Another unusually strange play based on bot's clairvoyance..... east bot rising with an ace capturing south's singleton king with no bidding or dummy holding to suggest an unusual distribution.

If Robot were a real person it is doubtful that he/she/it could play more than half dozen hands before being physically attacked by his/her/its partner. While his/her/its bidding is often questionable, his/her/its opening leads are absolutely off the wall terrible.

Over the course of 100 defensive hands Robot failed to lead partner's bid suit 77 times. Of the 77 times, 5 were K A, 5 were three card sequences, 6 were top of nothing, 6 were singletons and 27 were doubletons. 42 of these 77 leads resulted in a net loss of 1 or more tricks. The 23 leads of partner's suit resulted in a net defensive trick loss 4 times. Robot is a p-poor defensive leader!

What constitutes a biddable suit in robot world?
