Pard dealt as North and opened 1N (15-17). RHO overcalled 2C (alerted as natural). Sitting with the 7-4-1-1 hand and not playing doubles as stolen bids, I ventured a "confusing" 3H and we ended up in 4H, making 7 when they did not find the spade lead. My question is : How would people show such a hand and bid it to slam? Also what would 3C over 2C mean here?
TIA!
