GIB plays 4NT on the first round as RKCB, 5C shows 0 or 3 key cards in diamonds, and it doesn't understand you sometimes want to play in a different suit.

Bingo - for all the complaints BBO gets about GIB playing strong jump shifts, it makes hands like this one quite easy.
Please let me know about any questions or interest or bug reports about GIB.
