GIB seems to have a problem with the diamond suit. Numerous times GIB will open 1 diamond and I will respond 2 clubs. GIB then bids 2 diamonds. Holding 4 diamonds I will then support diamonds only to land in a high level diamond contract when GIB started with only 3 diamonds. One time GIB bid diamonds 3 times with 3. Just now, the opponent opened a diamond, GIB bid 2 clubs, this was followed by 2 diamonds. I then made the mistake of bidding 3 diamonds which was passed out.
