Terrible board

First of all I don't understand how South can calculate 2H being better than playing against 2D

Then I see no reason for West to bid Twice on such a bad suit

Then I do not like bidding 1N on a 17 count with a singleton, but also noted that the 2C rebid here is limited to 14 HCP

This could be a plan

Now we also have a problem in this sequence

2D could be right and match the explanation
But Why is West now doubling on a bad suit?

After the strength cuebid I have no doubt that North should drive to game, but no.

And it is getting worse

And finally how I noticed this board as this is from BBO playing with GIB

where 3C is forcing

1N because currently 2C means 6+C.
W double means 6+D.
Next BBA
