Noooo... What was fixed is that GIB will lead its Ace if it has one, not play its Ace when led to B-)

Another thing that needs to be fixed - after the 3S jump, 4NT should be BW for Spades. Mind you it was this player's own fault for not checking the description. Too bad he was rewarded for it instead.

South wants to ask RKC(D): the cards he's interested in are A, K and A. He had a brain cramp after asking the question, but he asked the right question.

Dummy GIB told me about this hand. He was relieved you didn't unblock !DQ under the A - he was very worried about how much a beer claim in 7N XX making would cost.

This was my only human adversary in the competition. I settled in a sensible 6N+1 on the same defence. I cashed A at trick 2 and claimed 13, expecting at least to halve the board.

Not quite so ridiculous to duck at my table, but still pretty bad, especially at MP.

May I add, what a complete waste of time and resources it was to program GIB to lead an Ace against 7N, when half the time it is his partner with the Ace? It betrays to my mind a lack of understanding why it is so bad, which is that (at least at MP scoring) GIB's philosophy seems to be simply to maximise its expected number of tricks without placing any premium on the value of defeating the contract. It is a policy that might have some legs at lower levels, but not at the 7 level, and not where they have bid the contract to make. If instead of wasting time hard coding it to lead an Ace they instead coded it to beat the contract regardless of later consequences for number of undertricks, and only then revert to the policy of maximising undertricks, then this might not happen.

I wonder if GIB has trouble generating hands for South? It seems like on the auction it's easy to construct lots of hands where south has KC, 3 diamonds, 6-7 spades 2 hearts would be 13. So I think they have to get into the hand dealing algorithm so it becomes more obvious that taking the ace is critical.

I wonder also if East should be doubling 7nt. How will his partner know to lead clubs?

I suspect not, I think he just didn't look at the description and thought 4NT was RKC for S, or straight BW.

But that's not the point. Don't you think it SHOULD be for Spades? If you find all the Aces you can then ask for Kings.
