Doubling even a strong 1NT for penalties is a fairly common occurrence.

So i was somewhat surprised to find what my 2S bid meant to GIB was not showing any bridge logic.

My left hand Robot opponent started the bidding:

!NT double pass 2S
all pass.

My Robot partner penalty double apparently promised 16+ HCP.

I wanted to play in 2S but my 2S bid apparently meant:
11- HCP; twice rebiddable S' 12- total points

Surely there are two problems here:

I am unlikely to hold 10 HCP and if I did hold 9 or 10 points I would not be making a signoff in 2S.

The descriptions of the meaning of the Robot double and the my 2S bid are not mutually consistent.

Which one or both need correction for this reasonably common situation?

Ari recently increased the requirements for the double. Maybe he didn't update the responses to adjust for this.

I think the generaly idea is that if you pull the double you don't have enough to bid game.
