See Gib E's hand.
Gib E has a five cards ♥ suit and good 11hcp with exact 12TPs, as we know that the standard of major opening at one level is " Major suit opening --- 5+♥,11-21hcp,12-22TPs. " Why not opening?
So I have to make many similar hands to see what's the real definition.
Hand-1
Hand-2
My conclusion :
The real definition of major opening at one level is " 5+major,13+TPs,10+hcp ".
BTW, I have a question in my heart, hoping Gib programmers can tell me : it is easy for me to find Gib's issues and post on this forum, and it also wastes a plenty of my time,I have been wondering whether I did many damages to your Gib programmer staff.
Would you tell me?
