MP, robot duplicate, best hand South, Traveller 6570-1373749321-69025440
Nothing strange about the bidding as shown above, which was repeated at several tables.
The only reason I bring it up is because some bright spark decided to open the South hand 1C, and it went uncontested 1C-1S-2S-All pass.
Now I am a simple soul, but I rate the North hand to be stronger after 1C-1S-2S than after 1D-1S-2S. Not stronger by a prince's ransom, but CERTAINLY not weaker.
So if GIB rates the hand worth a game try after a 1D opener how does it conclude that it is not worth a game try after a 1C opener?
