This hand is provided by a member of my bridge club.

Even though 4 is inappropriate,7 is also too wide of the mark.

7 says "5+,13+TPs",it only own 12hcp with 12TPs in fact,never 13+TPs.

Let us review, yet again, how GIB counts total points...

 

First, count high card points: A=4, K=3, Q=2, J=1

Then, count distribution points: Void=3, Singleton=2, Doubleton=1

Finally, add total points plus distribution points, and subtract one for every suit in which you have counted both high card points and distribution points. For example:[hv=pc=n&n=sah5432d5432c5432]133|100[/hv]To count this hand: 4 for A + 2 for singleton - 1 for counting twice = 5

 

So, in OP's hand, North gets: 12 HCP + 2 for singleton - 1 for counting twice = 13 total points

 

But yes, 7 is absurd.

single Ace= 5 ?

Max hardy had ever said that this is very very absurd to overestimate its value,and actually approximately equal to 3,I think you know its value in your heart.

Mr. Goren said it was worth 6, and I still believe him. But the bigger message is that since it seems unlikely that there will be a revamping of GIB's point counting routine anytime soon, players should know how that routine works.

I think the idea is that if you value x-xxxx-xxxx-xxxx as worth 2 total points in say a heart contract, for the spade ruffing value, it's not unreasonable to value A-xxxx-xxxx-xxxx as 5 total points, for the ace and the ruffing value combined. I don't have a problem with this. x-Axxx-xxxx-xxxx is 6.

 

Where I think GIB underevaluates is mainly when it possesses good 6 and 7 card suits where it should add a bit more for those rather than just counting 1 point for doubleton, 2 for singleton etc.

thank you, I accept its having 13 total points now.
