I have played with robots quite a lot and usually find their bidding reasonable. This is my first post to this forum, so hope this is appropriate content. If not, apologies in advance. A hand come up today that I think shows a bug in the bidding database or algorithm. In 4th seat with 4 Q75 AK765 AJ83, the auction was: P P P 1D P 1H 1NT X (sandwich NT and support X) 2S P P 3C GIB explains 3C in this auction as showing 5+D, 3H, 5+S, 21- HCP. I think it should be 5+D, 3H, 4+C, 21- HCP. I didn't check before bidding 3C and the rest of the auction is not pretty. I realize my 3C is pushy but I didn't want to sell out with a singleton S, though double might have been a better bid. http://tinyurl.com/y8sazzdx
