Strange interpretation of auction

[fhacker]

My robot partner opened 1D and I responded 1H. Opposing robot overcalled 1S. Partner robot doubled to show 3 card support. After opponent's pass, I decided to ask for key cards.

My robot partner passed 4N. I was stunned to read that the robot thought I had 4+ hearts and 6+ points.

That's definitely an accurate description of your hand :P but that's what happens when you don't check the meaning of bids before making them :) Of course, sometimes the online description and GIB's interpretation isn't the same and you end up in a different ridiculous contract. There's no way to get these right every time.

I also would have thought that 4NT is asking for keycards, for what else could it be, but sometimes GIB just isn't programmed that way. I recomment to make a habit of always checking the bid before clicking it. In some cases as this one, you have to confirm the fit before you can ask for keycards. 3 cards opposite five was not considered a sufficient fit in this case by GIB. In order to confirm the fit, you can often overcall opponents' suit. In this case 2♠ still shows only 4+ ♥ but 3♠ shows 5+ ♥. 3♠ is your bid! Opener would probably bid 4♥ (or cue bid) upon which you can ask for keycards with 4NT.
