Fortune favors the brave, except in BBO.

 

It's long since been reported that one of the updates reduced the range of a 1NT rebid after a take-out double to 12-14 HCP. This silliness opened a gap between an immediate 1 NT overcall and double followed by a 2NT rebid (21-23, if I recall). On this hand, as so often on BBO, it paid to underbid. Those who doubled and rebid 1NT or overcalled 1NT directly with their 20-count did fine. Those who overbid very slightly by doubling and rebidding 2NT ended up in the soup - begging the question as to when this gap will be addressed.

I agree. This egregious recent programming error should be BBO's top priority to fix. I'll leave it at that, and hope they act quickly.

First double then rebid-1nt only shows 12+TPs,so I guess it may be a bug?
