Well I passed the first time. I had a friend make a plug for 3♣ but I'm too balanced and too weak, in my opinion.
So partner reopens.
Where is the line? In trying to come up with a hand where I would bid 3♣ now, I kept getting hands where I would have responded 2♣ before. Doesn't mean that this is a 3♣ bid, probably I should just bid 2♣; but, IS there a hand that would bid 3♣ this way?
(P)-P-(P)-1♣
(1♥)-?-(P)-1NT
(P)-?
