Result -870 (after a spade lead). Couldn't Northbot have found a heart bid?

Nope, you're playing with the wrong brand of robots if you are expecting a takeout with that hand.

[DrFell]

Maybe the robot was playing with the wrong brand of human.

my sympathies. GIBBO is nuts. I wonder what the rationale for pass is. Jdonn?

There is no rationale. This is what we in the software industry call a bug - behavior different from what the implementer intended.

pass is pretty bad, but double is pretty bad too.

You think so? I reckon it was aggressive but not unreasonable.

For what it's worth, -870 was a popular score on this board, achieved at 27 out of 37 tables.

True. Sometimes you still have to double anyway.

the passers were all GIB_BBO's?

Yes, it was a robot tournament.

When you describe pass as "pretty bad" I'm reminded of a famous quote by the physicist Wolfgang Pauli who once said of a colleague's work, "This isn't right. This isn't even wrong."

Pass isn't pretty bad or even really bad. It's preposterous.

The worst you can say about the balancing double is that it's aggressive.

preposterous is right. possibly the millionth time GIBBO passes with such hands. seems to be a pretty easy bug-fix.

If it was easy, this would have been fixed years ago. As a software developer, I think it should be easy for a better designed GIB to be fixed. But we are basically stuck with the GIB that was originally designed 25 years ago.

and yet one of the stephens gets better results from old GIB on PC.

4 things.

1. Basic bots (I assume that's what OP was using. OP can correct me if I'm wrong) make frequent embarrassingly bad mistakes and BBO basically disavows fixing most of them.

2. Fixing 1 thing breaks another thing, and fixing 1 auction doesn't fix a very similar auction. This seems to be a major problem with GIB programming.

3. The old standalone GIB has the full and unlimited resources of the computer it is run on. The BBO bots have limited time sharing of network resources.

4. I'm (just) guessing the BBO bots occasionally do better than the standalone GIBs.

[jdonn]

Yes doubles and passes of doubles are bad, but I think this is more related to the badness of balancing auctions than the badness of doubles. I still think at some point balancing auctions will be worked on all at once in a major overhaul.
