Thank you very much for the detailed responses! I like the 3N non-slammy, and other suggested 4-level responses. The actual hand was: ♠T9xxx ♥QT9xx ♦x ♣xx Gwnn you're probably correct that the undiscussed 4♥ bid was dangerous. I was playing with an ex-Australian rep, and he presumed I had roughly Kxxx,Kxxx,xx,Axx and so bid 6♠, two off. I thought my bid was a two-way shot, thinking that partner probably had the big balanced hand, but on the off-chance he didn't, I wanted to make sure RHO's next decision was at the 4-level (many partnerships pass a 2♦ multi initially with 16+ for better or worse).
