In a daily tournament, I was 3rd hand and the bidding went 3♠(4♣)4♠(X);p(p). I had a decent hand and thought we would make it so I decided to redouble. GIB inexplicably pulled the redouble to 5♣. The explanation is that the bid shows a first round control (it happened to be a void). This is a terrible bid. There is only one scenario where playing a redoubled contract is worse than bidding on - 7♠ vs. 4♠XX nonvulnerable. As if +1480 vs. +1510 makes much difference in any form of scoring! Of course the hand only makes 4♠ so this was about an 18 IMP swing. Ouch.

GIB should never pull a redouble that shows values.

I've looked at all of the pinned posts and can't work out how to create a simple diagram so here is the link to the hand as played.

Obviously not something the most novice human would ever do. Part of the problem is defining the XX by point count. Of course it means I think we will make! But it is still hard to imagine why GIB does anything but pass.

Good reply.
I think all the main problems are defining the xx by TPs count. This meant it was xx TP count explanation caused the disaster.
Now I would take this issue to enlarge its ranges.
Hand-1 Here is Slar's hand.

Hand-2 Here is a normal Gibs sequences.

Hand-3 Here is my hand to enlarge this issue.

Obviously, if without worse x/xx TP count explanations, there are not such rediculous stories.

Of course, this may be a weak area for Gib.
