While playing 2 over 1 where a responders bid of 2 in a new suit shows 13 or more points (we open with 12 points) and is game forcing then a 1NT response to a Major opening by partner would show upto 12 points (is that right?)
And to a 1 of a minor opening bid it would show upto 10 points.
So, the bidding goes:
N E S W 1H/S P 1NT P ... 1NT bid shows up to 12 points and is one round forcing ?
1d/c P 1NT P ... 1NT bid shows up to 10 points and is NOT forcing ?
How do you tell when a responder is using a 6-9 point non-forcing 1NT versus a 6-12 point forcing 1NT?
