I do not understand the bidding at all.
1-Partner passed 1NT, so it does not look like he/she has a big hand.
2-It would sound reasonable for Partner to assume that South's hand may provide one trick (just bid 1NT), may be one and a half! Now suddenly, partner has found 5+ defensive tricks? where are these coming from? Did the 2D bidder go crazy?
East's bid isn't very safe but some people would surely make it, and he is down 5. Why should you let him get away? Obviously that is better than expected, but there is no reason that even if the hand is more favorable for them they couldn't be down 2, or 3, or for that matter 1. Partner doesn't need 5 rock solid tricks to double, just good defense and good diamonds and assuming some help from our hand. Even when they make it it's not doubled into game, -180 is lose 3 imps against the same contract, no big deal at imps.
Please let me know about any questions or interest or bug reports about GIB.
