(2♠)-3NT:when i hold 20HCPs and a balanced hand with ♠ stopper ,what i overcall after 2♠ preempt? i think 3NT only. total 32HCPs means the natural 4NT bidder's hand is between 19-21Hcps,so it's not practical. (2♠)-x-(p)-3♠ (p) --4♠ this is (1444/16HCPs+) or (20HCPs/balanced/without ♠ stopper).4minor is forcing now,so 4NT is the blackwood.for example: A KQx KQJxxxx KX When i hold this hand,i can't bid 4♦ since my need for partner is Aces ONLY,and i am afraid his 5♦ raise when he hold as below: Jxx AJx Axx QJxx Of course i can raise slam opposite this hand,but when i change ♥ k to ♣ace: A Qxx KQxxxxx AK did you think is it enough for your raise small slam? how to handle when i hold a 20hcps and 5-5both minors?(EG:AK x AKxxx AQxxx ).i deem it isn't 4NT,4♦ then 5/6♣ ,or 5♠ leap directly. sorry for my edit 2times
