Auction proceeds ... 2D 2N. Then responder bids 3N, which according to its description 3-8 HCP which is what I would expect. Actually I would hope for a bit more than 3 as one-sided 3N contracts on minimum points are often tricky.
However very surprised to see robot has only 1 HCP and no easy entries. Contract goes down 2.
Robot must pass 2N surely?
3NT explanation says "2-5C; 2-5D; 2-4H; 2-4S; 3-8 HCP"
Big image follows....
