3♥ works for me, but how do you differentiate a 15 hand vs an 18 hand?
There are various structures, but the one we are using (our range is 14/15 ... 18/19)
can be found in
https://www.amazon.d...e/dp/0575061146
Basically
2C is a ask, showing a hand with a good 7 onwards
#1 2D says opener is min, i.e. 14/15
#2 answers on the 2-level are mid range, i.e. 16/17, telling something about the
major, 2NT denies certain major holdings
#3 answer on the 3-level are max range
The seq.
1C / 1D - 1H
1NT - 2S
showes exactly 4-4, 8+
Jumps to the 3 level by responder show add. distribution, usually 5-5
2NT by responder is a relay to 3C, 3C can be passed by responder, i.e. with max. and good clubs
opener has to break the xfer
after 3C, responder showes shape, 5-4.
Rebidding his suit, showes 5 in his suit and 4 clubs bidding NT showes 5332
It works, and is not overly complicate.
With kind regards
