Result : 3♠E-2
We know that south should cuebid 2♠ normally instead of pass. But I am surprised to see its forcing 1NT. So I would decide to make several experimental investigation of the definition on forcing 1NT.
***************** When with 3-card support :
- Hand-1
Result : 4♠E-1
Even west Gib has only 3hcp, but it responds forcing 1nt due to 6TPs with 3-card ♠ support.
3♠ says 3♠,6+hcp", obviously this is a helpless lie, where is 6hcp in its hand?
- Hand-2
Result : 4♠E-2
This hand would prove that even west Gib has only 4hcp, but it responds forcing 1nt due to 5TPs with 3-card ♠ support.
Same fortune, 3♠ is a helpless lie.
- Hand-3
This hand would prove that even west Gib has 3-card ♠ support, it can't respond due to only 4TPs.
*********************** When without 3-card ♠ support :
- Hand-4
-Hand-5
-Hand-6
Even west Gib has 5hcp,8TPs, it doesn't respond.
- Hand-7
Now you see that west Gib would respond forcing 1nt eventually with 6hcp
My conclusion :
The golden standard definition of forcing 1NT are :
- When with 3-card support, it only shows "3-♠,, 5+TPs,forcing".(It has nothing to do with HCP - TPs is preferred.)
- When without 3-card support, it only shows "3-♠, 6+HCP, forcing".(It has nothing to do with TPs - HCP is preferred.)
Existing problems :
- TPs with shapes is not necessarily more bigger than hcp in the some situations.
- The developers are a bit superstitious on Total Points evaluation.
It is appreciated if you would point out my wrong.
