I guess this one has been beaten to death (even in worse cases where the robot had a major fit), but as we continue to pay for it

minimum takeout response in minor repeated, with 4 cards explained as 5

If that's worst what N. Bot did to you, you have a charming life

I think this is quite dissimilar to other topics about rebidding suits, actually. It's not rebidding the suit for normal reasons - it's bidding it based on simulations only:

- it thinks the opponents will never double (GIB's book doubles are hopeless)
- in fact in most cases it thinks East will bid game (even though the humans that came before were just about to pass out 2NT)

While it "knows" West has shown 12-14 HCP and East exactly 12 HCP (rubbish database definition), it also knows it holds 7 and South holds near opening values too.. those don't add up, so it trusts you more than the opponents and expects a nice score defending game.
