If you play this way you can only show invitational and GF hands. IMO, it is more useful to assign one bid to competitive hands, and the other to F1 or better hands.


True. The main argument for responding with 6 points
is one must keep the bidding open for partner. In this
auction partner will get another chance. Also all those
6 point responses are on the one level.

Do you really need to bid 2 with this crap?

Qxxxx, KJx, Jxx, Jx

I would also pass this hand. 2 shows 8-11.
That doesn't mean one is required to bid with 8.
It means if he does bid he may have as little as 8.

That's a 6 card suit.
Notice that I stated with a 5 card suit.

Should add that the valuation model utilizes
both trumps and HCP.
E(tricks) = trumps + (HCP-20)/3 + e

And can be improved by considering skewness/flatness
E(tricks) = trumps + (HCP-20)/3 + SF + e
