If you're playing bergen raises, where a 3m bid promises 4 card support and a certain point range, while a double raise is weak, how would you bid this?
The problem is, this is a 6 card limit raise. If partner has something like
♠ Ax
♥ AKxxx
♦ QJx
♣ xx
Then you want to play in 4♥.
If partner has roughly
♠ Qxx
♥ AJxxx
♦ Qxx
♣ Kx
Then he'll want to pass quickly.
If partner has a bigger hand like
♠ Qxxx
♥ AKxxxx
♦ AQx
♣ -
Then he'll make a slam try. (yes, I gave both sides 12 card fits)
So how do I invite with this support? Do I lie about my trump count?
