Shaking and Trembling - because I don't have 14-16 "points" - I pass the redouble. Lesson: double right away 'cos later this sequence becomes 14-16

Note w/o dK lead is down 2 possibly.

I had already started calculating +2xx or even +3xx vulnerable. But it was 0.5 cents so I took a chance.

Related to a previous post where GIBBO had passed a redouble and was the right bid.

Weird that the delayed double should show that much, should be lower range. It's probably having a hard time constructing hands for N/S, not accounting for light 3rd seat opener and might be over-rating pass based on an unrealistic sample. Also an issue is that it doesn't have a scrambling 2nt available to show equal length in the minors, it probably realizes that getting to a 4-3 fit might be fairly frequent and bad and thus might make the risk of passing 2H look better since 3m also minus. I wonder what it would choose if it could bid 2nt to get to an 8 cd fit reliably.

that sequence always has been 14-16 "points". i.e. your gib passes next hand bids you pass and 2 of same by lefty. pass, pass, double is 14-16. if you bid a 4 card suit now your partner gib is forgiving.

weird the balancing takeout double is stronger than direct take out double. though GIB's direct or delayed takeout doubles are quite bad. i have stopped doubling opps if my gib makes a takeout double.

How is this wierd?
Almost every balancing sequence where in normal bridge all you need is 13 cards and shortage in opps trump suit, Gib says this shows a big hand.
In most of these sequences it would be very rare to come close to what Gib is requiring.
