1N is generally 9-11ish as a response to an overcall in this partnership. Two questions on this hand.
1). 2N would be the lower two unbid suits, and you've agreed only to do that with good playing hands at this vulnerability. With those partnership agreements forced on you, do you agree with 1♥?
2). Having been forced to have this auction up to this point, what would you bid now?
(1♦)-1♥-(p)-1N,
(p)-2♣-(p)-2♥,
(p)-?
