playing in NT instead of the known Major suit fit

I have been asked to post (within reason) clear bidding errors in Robot tournaments, so here is another ...

Clearly, the Robot should bid 4 over 3 instead of 3NT (because of the known 8+ card Major suit fit). The description (which you can confirm if you must insist on clicking on the picture) describes the 3NT bid as showing 4 s and no more than 3 s. If that is what the Robot actually held, then I would definitely agree with the 3NT bid. Here, however, the Robot holds 4 s and only 2 s.

 

I hope that GIB does not peek, since 3NT is cold against any defense and 4 can be defeated with any reasonable defense, but that is the only rationale that I can imagine for the Robot's 3NT bid.

Yes, Steve, playing Results, you certainly belong in 3NT instead of 4. In a tournament, I would be rewarding such good fortune by assigning a Monitor to watch that Pair.

 

This hand was reported to try to have an apparent programming error corrected.
