As dealer, vul against not, you hold: 94 / 1075 / 108642 / 743.

The bidding goes:

P P 1D 1H
P 3D* 4C P
P ?

* = mixed raise, 4+ H, 7-9 total points, forcing

Your call?

My robot partner held the above hand and passed. Why not correct to 4D?

Now that I look at the description of my 4C bid, I see that it says "4+ D, 19 HCP, rebiddable C, 22 total points." I actually had 5 diamonds and 4 clubs. So maybe that's the problem. But with 5 diamonds and 4 clubs and a big hand, am I supposed to open 1C? I had A52 / K / AK953 / AK102. Should I have bid differently? Or is this the robot's fault for leaving it in 4C?

Short answer is the robot should have corrected you to diamonds, based on its own interpretation of your bid, even if your hand was 5-4 in the minors, instead of 4-5 as it suspected. The AI for the robots is particularly lacking in basic sense in certain situations.

I think if GIB has 6 or 7 diamonds it would still have passed 4 clubs. The way to get GIB to preference diamonds is when it has a singleton or void in diamonds and 5 to 8 clubs. Of course, that's not a workable plan since you don't control what GIB holds.
