I noticed a bid that I can't seem to figure out. Free robot tourney, MPs. Consider this:

And then this:

What's the big difference that makes it so slam is worth checking for after 2nt opening but not after 2c opening? The 3c shows the same thing in both cases. And 4s shows 3+ spades in both cases. So what are the differences? Well the 2nt is necessarily balanced and has fewer total points. Both of which should be considered worse at going for 6s.

responder is showing a bigger hand making a free bid over 2♣ than 2N so doesn't feel compelled to bid on.

still Gib shouldn't be looking for slam opposite a 2N opening just cause it has extras, it doesn't have enough for slam.
