I was rather annoyed that GIB couldn't leave 3nt in on this hand. Maybe if 3nt were more tightly defined it can find the pass?
- why is only limited to 3-H? Shouldn't it be 1-2 hearts?
- why 15-22 hcp, makes no sense? Maybe 12-17 hcp?
Somehow it should be excluding hands that would choose 4h over 3h. and simulate on that basis.
