I found the hard way (-10 IMP), that New Minor Forcing in the sequence

1H-1S
1N-2mi

is not clear what the difference between 2C and 2D is and BBA does not explain. Some suggest it is a stopper

Please also add, that both 3H and 3S after 1N is invitational (so 2S is more like 6-9(10) - that apply to all sequences

As there is no difference between 2C and 2D GIB is only using 2C and 2D is then natural and non-forcing

Better minor, at least 3, very likely stopper.
