Even vulnerable I think most of us will bid 3♣.
2♣=5+♣, 11-15 HCP, 12+ total points
And now 3♣ is defined as 6+♣, 15- HCP and 17+ total points
Now partner has the following hand
and bids 3♦ showing 7+ HCP and 8 total points.
I bid 3N just hoping for the best and went down 6 vulnerable - ouch
Now in the replay (It was a robot challenge) my opponent did even worse
Only way out is 4♣
I think that in this sequence North should have at least (9)10 HCP / Total points to GF
